Mediator API Reference

The hosted Mediator Application Endpoint acts as an intermediary between phone numbers. The service has two primary abilities, bindings and dialouts.

• With bindings, incoming calls are routed through CarrierX to a destination phone number.

• In dialouts, the CarrierX system makes outgoing calls to two different parties, who are then brought into a call together.

Using the REST API

This section describes how to obtain credentials to use the API, what types of requests the system recognizes, and the format of the responses. It also holds reference information about pagination, filtering, and callbacks.

Using Postman

This documentation contains cURL commands that you will run in your terminal. Rather than use these commands, you can explore the API using Postman, a stand-alone client with a user-friendly interface. Postman is widely used for API development and allows you to test requests.

You will need to download the Postman client to your computer. To do so, visit the Postman website and click Download. Click Run in Postman to import this collection to the Postman app.

Main Conventions

The following conventions are used in the sections, which contain the tables with objects attributes, their types, and descriptions:

Authentication

The following curl command will return a list of all of the endpoints of the CarrierX account associated with the login credentials. Use your Core API token in the query below. The endpoint login and password values are listed in the returned JSON object.

curl -X GET \
'https://api.carrierx.com/core/v2/endpoints' \
-H 'Authorization: Bearer 5ebc03d6-8b2b-44ad-bf65-72d4f1491dda'

The credentials of a specific endpoint are found in the properties attribute of the nested object. Locate the login and password values.

All CarrierX API requests require authentication. The first step to using CarrierX API is obtaining a CarrierX account and gaining credentials. To do so, please submit a request through our Contact Us page.

Currently, CarrierX API requests use two types of authentication:

• Bearer token, used by the requests to the Core API.
• Basic HTTP authentication with login and password, used by the requests to the endpoint APIs (Conference, FlexML, and Mediator).

Prior to making requests, you need to create a Mediator application endpoint. Refer to the Mediator Endpoint quick start guide for step-by-step instructions on creating a Mediator endpoint.

Requests

Sample request to create Conference endpoint

curl -X POST \
'https://api.carrierx.com/core/v2/endpoints' \
-H 'Content-Type: application/json' \
--data-binary '{"name":"my_conf", "type":"conference"}' \
-H 'Authorization: Bearer 5ebc03d6-8b2b-44ad-bf65-72d4f1491dda'

The requests in CarrierX API are made using the standard REST notation, typical for web services.

A simplest request will have the following structure:

• The request URL to which the request will be sent. The URL will be different for the Core API methods and for the main endpoint-related requests (conference, FlexML, mediator).
• The request method or the verb used for the REST over HTTP request.
• One or several headers or user/password authentication.
  • At least one header—-H 'Authorization: Bearer 5ebc03d6-8b2b-44ad-bf65-72d4f1491dda'—is required to access the Core API.
  • For the requests to the conference, FlexML, or mediator endpoints, CarrierX uses the basic HTTP authentication with login and password (cURL -u option).

  Refer to the Authentication section for more details on this.

All the above elements are required for all CarrierX API requests.

Other request may have additional structure elements which include:

• Path arguments are required with some methods to access specific objects (GET the object by secure ID, PATCH/PUT, and DELETE objects).
• Body payload is required with POST and PATCH/PUT. Even if the object method does not require any body arguments (e.g., POST for some objects), the payload must still include an empty object (--data-binary '{}').
  
• Query arguments may be either optional or required for some requests. Refer to the objects sections below to see which object methods require the presence of the query arguments. The optional query arguments available with some GET requests include pagination, result filtering, and field filtering.
• Form data is required with some POST methods, e.g., uploading a file to the container using multipart/form-data content type.

Request URL

The usual path to the API objects includes the base URL to the API used with the object (Core API base URL for the objects used throughout the CarrierX products, or specific API base URLs used for FlexML, Mediator, or Conference), and the path to the object collections and the object items.

If the action targets the specific object, the path to it will include the object secure ID (SID), which allows to distinguish the targeted object from the other ones in the same collection.

The system only accepts HTTPS requests, and not HTTP requests.

Request Methods

CarrierX API uses five main verbs (methods) of REST over HTTP for the requests: POST, GET, PUT, PATCH, and DELETE. These methods are used to create the objects, get the information about the objects, modify the objects, and delete them.

CarrierX partners need to have special permissions (or scopes) to use API methods on various objects. Refer to the available_scopes table for the complete list of the scopes that define the partner’s permissions on objects and collections.

POST

Sample POST request that creates a trunk

curl -X POST \
'https://api.carrierx.com/core/v2/trunk_groups/138ed522-6633-405b-b58d-55eb0d262e32/trunks' \
-H 'Content-Type: application/json' \
--data-binary '{}' \
-H 'Authorization: Bearer 5ebc03d6-8b2b-44ad-bf65-72d4f1491dda'

The POST method is used to create new objects. When you create a new object, you usually need to specify at least some of the attributes for the object to be created in the request payload.

The successful POST request will return a 200 response with the serialized JSON copy of the created object.

GET

Sample GET request that returns the currently logged-in partner

curl -X GET \
'https://api.carrierx.com/core/v2/oauth/whoami' \
-H 'Authorization: Bearer 5ebc03d6-8b2b-44ad-bf65-72d4f1491dda'

The GET method is used to view the information about the existing objects and their collections.

Generic GET requests return the list of all the objects (or collections) available for the request sent. Most of such GET requests can be used together with Pagination, Result Filtering, and Field Filtering.

GET requests aimed at a specific object require to use the object secure ID to be included as a part of the request path, and return the information about the specified object only. Most of such GET requests can be used together with Field Filtering.

The successful GET request will return a 200 response with the serialized JSON copy of the requested objects (or specific object).

PATCH/PUT

Sample PATCH request that modifies or adds a new name record of the nested attributes object

curl -X PATCH \
'https://api.carrierx.com/core/v2/partners/aeda835c-6627-4f4c-ac73-9edcae95640b' \
-H 'Content-Type: application/json' \
--data-binary '{"attributes":{"name":"New Partner Name"}}' \
-H 'Authorization: Bearer 5ebc03d6-8b2b-44ad-bf65-72d4f1491dda'

Response The serialized JSON copy of the created object together with the nested object

{
    "attributes": {
        "name": "New Partner Name"
    },
    ...,
    "partner_sid": "ed437757-001d-4ecc-aa5a-efdf5e50dba0"
}

Sample PATCH request that adds a new name2 record of the nested attributes object of the same Partner object

curl -X PATCH \
'https://api.carrierx.com/core/v2/partners/aeda835c-6627-4f4c-ac73-9edcae95640b' \
-H 'Content-Type: application/json' \
--data-binary '{"attributes":{"name2":"New Partner Name 2"}}' \
-H 'Authorization: Bearer 5ebc03d6-8b2b-44ad-bf65-72d4f1491dda'

Response The serialized JSON copy of the created object together with the modified nested object

{
    "attributes": {
        "name": "New Partner Name"
        "name2": "New Partner Name 2"
    },
    ...,
    "partner_sid": "ed437757-001d-4ecc-aa5a-efdf5e50dba0"
}

Sample PATCH request that modifies the entire nested attributes object of the same Partner object

curl -X PATCH \
'https://api.carrierx.com/core/v2/partners/aeda835c-6627-4f4c-ac73-9edcae95640b?nested_objects=replace' \
-H 'Content-Type: application/json' \
--data-binary '{"attributes":{"name3":"New Partner Name 3"}}' \
-H 'Authorization: Bearer 5ebc03d6-8b2b-44ad-bf65-72d4f1491dda'

Response The serialized JSON copy of the created object together with the nested object

{
    "attributes": {
        "name3": "New Partner Name 3"
    },
    ...,
    "partner_sid": "ed437757-001d-4ecc-aa5a-efdf5e50dba0"
}

The PATCH/PUT methods are both used to modify the existing objects and their attributes. The difference between them is explained below.

PATCH is used to modify only some of the object attributes and does not require to send the entire object in the request payload. Only the attributes and their values that need to be modified can be sent in the request body.

Objects can have a complex structure and can contain other objects as part of them, i.e., nested inside them. When you use PATCH and want to modify the nested objects, PATCH follows the below rules to define what must be updated and how:

1. If the existing nested object contains the same record (by key), the existing record will be replaced with the new value, provided in the PATCH request. The other nested object records will remain unmodified.

2. If the existing nested object does not contain the same record, a new record will be added to the object. The other nested object records will remain unmodified.

3. If the existing nested object contains the same record and the value of the incoming record is null, then the existing record will be removed. The other nested object records will remain unmodified.

4. If the PATCH request contains nested_objects=replace as a query attribute, the whole nested object will be replaced with a new one (i.e., all the old records and their values will be removed and only the new ones will be added).

PUT is used to modify the complete object and require to send the entire object (together with the nested objects, if there are any) in the request payload.

Both PATCH and PUT requests are aimed at a specific object and require the object secure ID as a part of the request path.

The successful PATCH/PUT request will return a 200 response with the serialized JSON copy of the modified object.

DELETE

Sample DELETE request that deletes an endpoint

curl -X DELETE \
'https://api.carrierx.com/core/v2/endpoints/1a34c5e9-3a09-4de5-b553-5f6a9ef202ac' \
-H 'Authorization: Bearer 5ebc03d6-8b2b-44ad-bf65-72d4f1491dda'

The DELETE method is used to delete the object targeted by its secure ID.

The successful DELETE request will return a 204 response code with an empty body.

Rate Limiting

Currently, CarrierX applies no rate limiting to the partners requests to CarrierX API.

Responses

All responses return conventional HTTP status codes. Most of the responses (GET, POST, PATCH/PUT) also return objects in the JSON format.

CarrierX API allows cross-origin (CORS) requests and data transfers.

HTTP Status Codes

Typical 200 status code in the response

HTTP/2 200
Access-Control-Allow-Origin: *
Access-Control-Expose-Headers: Access-Control-Allow-Origin,Access-Control-Allow-Methods,Access-Control-Allow-Credentials,Content-Disposition,Access-Control-Allow-Headers
Content-Length: 1333
Content-Type: application/json
Date: Wed, 22 Sep 2021 08:23:06 GMT
Server: nginx
Strict-Transport-Security: max-age=31536000; includeSubDomains
Vary: accept-encoding

The Mediator API uses the following HTTP status codes:

Sample 400 status code when the JSON sent in the request body has errors in its syntax:

{
    "body": {
        "message": "cannot parse json. Check json for validity",
        "errors": null
    },
    "status": 400
}

Sample 401 status code when trying to send a request without authentication:

{
  "message": "authentication required",
  "errors": [
    {
      "field": "cause",
      "message": "authentication required",
      "reference_sid": null
    }
  ]
}

Sample 403 status code when trying to access resources you do not have enough permission for:

{
    "message": "permission denied",
    "errors": [
        {
            "field": "cause",
            "message": "permission denied",
            "reference_sid": null
        }
    ]
}

Sample 404 status code when trying to access a non-existent object (e.g., a token with an incorrect SID):

{
    "message": "no item error",
    "errors": [
        {
            "field": null,
            "message": "cannot find token",
            "reference_sid": null
        }
    ]
}

The above status codes are common for all requests.

There are some error codes specific for certain requests only. They are described in the topics dedicated to these requests (e.g., error 422: Container Object Specific Errors).

Response Objects

Typical formatted JSON object in the response

{
    "callback_url": null,
    "did_group_sid": "41e21049-e5eb-433c-a93d-d57417b1863c",
    "name": "N/A",
    "partner_sid": "e00430c3-a7d0-4666-ab5c-f7202448382f"
}

Successful requests return objects in the JSON format with application/json set as Content-Type. The object keys and values depend on the request and the object returned, and are described in the corresponding object sections.

Normally, the system returns the object fields unordered and unformatted. To view the object fields ordered alphabetically and “pretty-formatted” in the response to the command-line requests (e.g., cURL), use the jq command-line JSON processor or similar tools.

With jq, the request will look like this:

curl -X GET 'https://api.carrierx.com/core/v2/oauth/whoami' -H 'Authorization: Bearer 5ebc03d6-8b2b-44ad-bf65-72d4f1491dda' | jq -S

Pagination

This request returns Country objects sorting them descending by the common_name attritute, starting with the second record available, and returns a maximum of two records.

curl -X GET \
'https://api.carrierx.com/core/v2/countries?offset=2&limit=2&order=common_name+desc' \
-H 'Authorization: Bearer 5ebc03d6-8b2b-44ad-bf65-72d4f1491dda'

To view records not included in the response, make a request to the URL value of the previous or the next key.

{
  "count": 2,
  "has_more": true,
  "items": [
    {
      "capital": "Sana'a",
      "common_name": "Yemen",
      "dialing_prefix": "967",
      "domain": "ye",
      "iso_3166_alpha_2": "YE",
      "iso_3166_alpha_3": "YEM",
      "iso_3166_numeric": 887,
      "mcc": "421",
      "official_name": "Republic of Yemen",
      "region": "Asia",
      "subregion": "Western Asia"
    },
    {
      "capital": "El Aaiún",
      "common_name": "Western Sahara",
      "dialing_prefix": null,
      "domain": "eh",
      "iso_3166_alpha_2": "EH",
      "iso_3166_alpha_3": "ESH",
      "iso_3166_numeric": 732,
      "mcc": null,
      "official_name": "Sahrawi Arab Democratic Republic",
      "region": "Africa",
      "subregion": "Northern Africa"
    }
  ],
  "limit": 2,
  "offset": 2,
  "pagination": {
    "next": "https://api.carrierx.com/core/v2/countries?limit=2&order=common_name+desc&offset=4",
    "previous": "https://api.carrierx.com/core/v2/countries?limit=2&order=common_name+desc&offset=0"
  },
  "total": 251
}

You can use the pagination to limit the number of the objects returned in the response and sort them by the object attributes.

The pagination is available for the GET requests which return the lists of the objects without targeting them by secure IDs.

The pagination parameters include:

limit

An integer parameter that determines how many items are returned in the response. The entered value cannot exceed 1000.

The default value is 10, meaning that a maximum of ten items will be returned.

order

A string parameter that allows to sort the returned objects. Three values are accepted for this parameter:

• attribute name + asc to sort the items in the response in the ascending or alphabetical order (default order).
• attribute name + desc to sort the items in the response in the descending or reverse-alphabetical order.
• shuffle to randomize the order of the items in the response.

offset

An integer parameter that determines the amount of items that are skipped in the response.

The default value is 0, meaning that the first existing item will appear first.

after/ before

This request returns a maximum of one record of SMS Detail Record objects following the object with the b6d574ea-b11f-41fd-a25f-602e7b28807f secure ID.

curl -X GET \
'https://api.carrierx.com/core/v2/sms/message_drs?after=b6d574ea-b11f-41fd-a25f-602e7b28807f&limit=1' \
-H 'Authorization: Bearer 5ebc03d6-8b2b-44ad-bf65-72d4f1491dda'

To view records not included in the response, make a request to the URL value of the previous key.

    },
    "total": null
}

For some objects (e.g., Call Detail Record or SMS Detail Record objects), the system will not return their total number. This can happen as the number dynamically changes in large quantities and can become not relevant by the time of the next request.

In this case, instead of using the standard pagination offset (which is rather difficult to calculate as the system does not return the total number of objects), you can use the after or before query arguments. With these arguments, the system will return the objects which precede or follow the entered object secure ID. This might be useful if you want to receive an exact range of the objects and know the secure IDs of the records which start and end this range.

Currently, CarrierX supports the pagination that uses the after and before arguments for the following objects and methods:

Request Parameters Combinations

You can use the following combinations of the pagination parameters:

• limit, offset, order: https://api.carrierx.com/core/v2/countries?limit=2&offset=2&order=common_name+desc

• after, limit, order: https://api.carrierx.com/core/v2/calls/call_drs?after=bb2aacd2-23d3-418e-9ec0-2fc45c5f9d76&limit=1&order=date_stop+asc

• before, limit, order: https://api.carrierx.com/core/v2/calls/call_drs?before=56fb6b94-811e-4952-b242-4e06f4e95b7e&limit=1&order=date_stop+desc

• after, before, limit, order: https://api.carrierx.com/core/v2/sms/message_drs?after=012e1d6a-75ac-43ec-bacc-68f1ef1c60a3&before=b6d574ea-b11f-41fd-a25f-602e7b28807f&limit=100&order=date_insert+desc

If you omit any of the parameters from the response, their default values will be used (if there are any).

Pagination Response

The JSON response for a successful query using the pagination parameters will include the following attributes:

Result Filtering

This GET request returns Endpoint objects that meet the filter criteria. In this case, we are narrowing the results to the conference endpoint type.

curl -X GET \
'https://api.carrierx.com/core/v2/endpoints?filter=type+eq+conference' \
-H 'Authorization: Bearer 5ebc03d6-8b2b-44ad-bf65-72d4f1491dda'

The following response includes all of the endpoints that fit the filter criteria.

{
    "count": 1,
    "has_more": false,
    "items": [
        {
            "addresses": [],
            "attributes": {},
            "capacity": 0,
            "endpoint_sid": "613325f8-bbb8-4599-b477-1b4fef3d017c",
            "name": "my_example_conference",
            "partner_sid": "6nelo9p3-3eef-4f75-8f48-fb98e99908be",
            "properties": {
                "account_sid": "bdrU77AFb-Y1sDwqqxkeb.M3LP7hSKYg",
                "api_url": "https://api.carrierx.com/conference/v1",
                "container_sid": "null",
                "login": "username",
                "password": "password"
            },
            "transformations": [],
            "type": "conference",
            "voip_token": null
        }
    ],
    "limit": 1000,
    "offset": 0,
    "pagination": {},
    "total": 1
}

The filter parameter is added to the query URL to restrict or customize the results of a JSON response by certain parameters (e.g., name, capabilities, state, country_code, etc.).

The structure of result filtering is as follows: filter=object_attribute filter_operator value. You can also use the and operator to combine several filters for more specific searches. For example, for a DID object we could apply the following filter: filter=state eq "NY" and phonenumber like "%555%".

Filter values can also be put inside single or double quotes. This is not necessary when the filter value is just a single word like USA. However, if your filter value consists of more than one word, the quotes are required. For example, name eq "filter value name".

Result Filtering Quick Reference

Field Filtering

In the following, we request Endpoint objects without the properties field.

curl -X GET \
'https://api.carrierx.com/core/v2/endpoints?exclude_fields=properties' \
-H 'Authorization: Bearer 5ebc03d6-8b2b-44ad-bf65-72d4f1491dda'

The following response excludes the properties field from returned Endpoint objects.

There are two parameters associated with field filtering: include_fields, and exclude_fields. By default, the fields included in JSON responses are specific to the request made. These returned fields are explained in the Object section for that object.

Refer to the specific object to determine which fields can be included and excluded from the JSON responses.

include_fields and exclude_fields accept comma-separated strings as values.

Field Filtering Quick Reference

API Reference

The Mediator API has the following sections: Bindings, Dialouts, and DIDs.

• Use the Accounts object to retrieve information about the available Mediator endpoint accounts.
• Use the Binding object to create call forwarding to specific phone numbers.
• Create and modify Dialout objects, which make calls to phone numbers.
• The DID object holds modifiable data about phone numbers rented through CarrierX.

Accounts

The Account object holds the data associated with the Mediator API. It is used to view information about the partner that is related to the Mediator endpoint.

Path Arguments

Bindings

Bindings enable call forwarding from one phone number to another. Bindings can be set to last for a specific amount of time or indefinitely. There are several types of bindings:

• Bindings that apply to all incoming callers. This type of binding can be created by setting wait_origination_did_ttl to -1 and not setting a value for origination_did.

• Bindings with one specified incoming phone number. A binding can also be restricted to a specific phone number, which means that the phone number specified will be subjected to the binding. This type of binding can be created by setting origination_did as a phone number in the E.164 format.

• Bindings with one unspecified incoming phone number. To establish a binding with an incoming phone number that is not explicitly defined at the onset, a period of time can be designated during which the first phone number that calls will be assigned to the binding. Once the binding is associated with the first incoming caller, the binding will apply only to that caller. This type of binding can be created by setting wait_origination_did_ttl to a positive number and not setting a value for origination_did.

Bindings are useful in many scenarios. For example, during a marketing campaign that lasts one week, a binding can be set up to forward calls from a rented phone number given to consumers. After the week is over, the binding will expire. The company behind the marketing campaign will not have to subject themselves to calls continuing coming in regarding that specific campaign.

Binding Object

This section describes the elements of the Binding object. These fields and values make up the JSON object that gets returned with successful requests.

In this section, there is also information about the optional fields that can be added to further customize bindings.

This request creates a Binding object.

Query Arguments

Body Arguments

JSON representation of the fields and values of the Binding object to be created.

A required field to establish a binding is destination_did.

Refer to this table to view all fields that appear in the Binding object.

Binding Variants

When creating a binding without a redirect_did specified, an available DID on the account will be assigned as the redirect_did. If no DID can be assigned for the redirect_did, the 409 error will be returned meaning that no redirect_did could be found. Verify that there are available DIDs that can be assigned as a redirect_did automatically.

The request will also fail if there is no available DID for the given origination_did.

Each binding has a maximum_ttl and wait_origination_did_ttl attribute. The maximum_ttl attribute is an optional field set to 3600 seconds by default, which can be changed to any duration of seconds. The binding will remain active until the value of this field reaches 0. After the duration of the maximum_ttl has elapsed, the binding will expire and be deleted. To extend the binding indefinitely, assign -1 as the field value for maximum_ttl.

Adding a value to origination_did will create a binding for that phone number only. If the origination_did value is not specified, the binding will apply to any incoming calling phone number. However, if the wait_origination_did_ttl field is set, the first phone number that calls in will be set as the origination_did and the binding will only apply to that phone number. If no call is received within the time period of wait_origination_did_ttl, the binding will expire and be deleted. To accept calls from any phone number before the maximum_ttl expires without binding the first phone number that calls, disable wait_origination_did_ttl by setting the field value to -1.

Path Arguments

Dialouts

Dialouts place a phone call to two phone numbers, and allow both people to speak to one another. Specifically, the redirect_did dials out to both participants in turns. Upon successfully reaching the parties, it brings them into a call together.

Dialout objects are not stored after the two parties have been connected. Only future dialouts can be searched for and modified. To schedule a future dialout, set the delay parameter to the number of seconds before the call will be set up. For example, if the delay parameter is set to 1000, the dialout will be initiated 1000 seconds from its creation.

Dialout Object

This section describes the elements of the Dialout object. These fields and values make up the JSON object that gets returned with successful requests.

In the second table in this section, there is information about the optional fields that can be added to further customize dialouts. These fields can be added when initially creating the dialout, or later using PATCH or PUT requests.

Sample Dialout object

{
    "account_sid": "13e156f7-0d21-4ba6-9e32-c56dc2c6098f",
    "attributes": {
        "hide_origination_did": "true"
    },
    "date_created": "2018-10-09T20:40:57.675Z",

    "stage_one_destination_did": "15162065339",
    "stage_two_destination_did": "15162065338"
}

Attribute Object

Below are the additional fields that can be added to further customize dialouts. All of these attributes are optional. Custom attributes can be added to the JSON object in the same method as the built-in attributes. Add these attributes as a nested object.

-u 'mediator_user_123:qwerty123'

Response 200 status code with a serialized copy of the Dialout object

        "redirect_did": "15162065340",
        "stage_one_destination_did": "15162065339",
        "stage_two_destination_did": "15162065338"
    },
    "status": 200
}

This request creates a dialout.

The common workflow is as follows. The redirect_did dials out to the stage_one_destination_did number. When that phone call is answered, the redirect_did dials the stage_two_destination_did. If the second phone call is also answered, the bridge is established between both parties. The Dialout object is deleted once the call has been set up.

The delay parameter can be set to a particular number of seconds. This is the amount of time before the redirect_did will contact the two phone numbers. If not defined, delay will be set to 0, meaning that dialing will start as soon as the Dialout object is created.

The stage_one_destination_did, stage_two_destination_did, and redirect_did parameters should be unique for each Dialout object. There cannot be two Dialout objects with the same phone numbers existing at the same time. When scheduling several dialouts, ensure each one has unique values for stage_one_destination_did, stage_two_destination_did, and redirect_did.

Additional attributes can be added to a dialout to customize the object. Refer to the Dialout object for a list of the built-in attributes available. Custom attributes can also be included in the same way as the built-in attributes.

Body Arguments

JSON representation of the fields and values of the Dialout object to be created.

Required fields to create a dialout are:

• stage_one_destination_did
• stage_two_destination_did

Refer to this table to view all fields that appear in the Dialout object.
