Introduction

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.

Refer to the Mediator products page for quick start guides and video tutorials. These hold walk-through instructions on configuring Mediator endpoints, creating bindings, performing dialouts, and looking up DIDs.

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 the App. Click Run in Postman to import this collection to the Postman app.

Credentials

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.

API requests require authentication. To obtain a CarrierX account and gain credentials, please submit a request through our Contact Us page. The Core API uses a bearer token, and the endpoint APIs (Conference, FlexML, and Mediator) use a login and password.

Prior to making requests, a Mediator Application Endpoint needs to be created. See the Configure an Application Endpoint quick start guide for step-by-step instructions on creating an endpoint.

Each of the application endpoints has different login and password values. Entering the Core API token credentials instead of the endpoint-specific credentials when working with the Conference, FlexML, or Mediator APIs will return the error unauthorized.

Requests

API requests require authentication. Refer to the section above for more information about obtaining login credentials. Endpoint credentials are passed using HTTP basic authentication. Pagination and filtering parameters are passed as part of the query URL. Object fields and values are added to the request body.

The Conference API has the following base URL:

https://api.carrierx.com/mediator/v1

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

Responses

All responses are returned in the JSON format with a status code. For common errors returned, refer to the HTTP Errors section.

Pagination

This request returns Call objects starting with the second record available, and returns a maximum of 4 records. 

curl -X GET \
'https://api.carrierx.com/conference/v1/calls?offset=2&limit=4' \
-u '[your_user_name]:[your_password]'

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

{
  "count": 0,
  "has_more": false,
  "items": [],
  "limit": 4,
  "offset": 2,
  "pagination": {
      "previous": "https://api.carrierx.com/conference/v1/calls?limit=4&offset=0"
  },
  "total": 0
}

The three optional parameters for pagination are: offset, limit, and order. GET requests use these three parameters to dictate how many items should be skipped in the response, the amount of records to return, and in what order the results should appear.

offset determines the amount of items that are skipped in the response. If there are five records and the offset value is 2, the response will not include the first two records. Instead, it will return records for items three through five. The default value for offset is 0, meaning that the first existing item will appear first.

The parameter limit determines how many items are returned in the response. The default limit is 10, meaning that a maximum of ten items will be returned. If the number of items that exist exceeds the limit value, the has_more value in the response will be set to true. Responses also have a total field, which is the total amount of results that match the search criteria. Note that the field total will be null on objects that are uncountable, such as SMS messages.

The last parameter of pagination is order. There are two values accepted for this parameter, asc and desc. asc is short for ascending and is the default order. Enter the field name to be ordered followed by either asc or desc. For example, name desc will return names sorted in reverse-alphabetical order. Since the default is asc, entering just name will sort the results by name in alphabetical order.

The JSON response for a successful query using the pagination parameters offset, limit, and order will include a pagination parameter. The value of pagination will be empty if there are no more records existing outside of the queried parameters. If there are existing records outside of the query, the pagination value will include next or previous URLs. These URLs can be used to obtain the remainder of the records available without modifying the original query. Simply construct another GET request with the URL provided in this field.

Pagination Quick Reference

Parameter Data Type Description
offset integer The amount of items skipped in the response. 0 is the default value. This parameter and value are added to the query URL.
limit integer The number of items to be shown in the response. The value entered should not exceed 1000. 10 is the default value. This parameter and value are added to the query URL.
order string The name of the field to be ordered followed by the order of the response data, either asc or desc. The field to be ordered is listed first, followed by the order value. For example: binding_sid desc. asc is the default order. This parameter and values are added to the query URL.

Result Filtering

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

curl -X GET \
"https://api.carrierx.com/core/v2/endpoints?filter=type+eq+'conference'" \
-u '[your_user_name]:[your_password]'

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 parameter filter is used to restrict or customize the JSON response. Operators can be combined for more specific searches, and are added to the query URL.

Result Filtering Quick Reference

Operator Definition Example
eq equal to. This search looks for exactly the value entered. In the example, results will have the exact value "my_mediator" for the name field. name eq "my_mediator"
gt greater than. This search returns records where the value is exceeded for the field listed. For example, records are returned where the value of maximum_ttl is greater than 40000. maximum_ttl gt 40000
ge greater than or equal to. This search returns records where the value is greater than or equal to the field listed. For example, records are returned where the value of wait_origination_did_ttl is greater than or equal to 70000. wait_origination_did_ttl ge 70000
ilike same functionality as like but case insensitive. name like "AccOUnt%"
in the current value of the specified field must be contained within the specified list. The following example will return records that have a status value of either "active" or "suspended". status in ("active", "suspended")
lt less than. This search returns records where the value is less than the field listed. For example, records are returned where maximum_ttl is less than 10000. maximum_ttl lt 10000
le less than or equal to. This search returns records where the value is less than or equal to the field listed. For example, records are returned where wait_origination_did_ttl is less than or equal to 90000. wait_origination_did_ttl le 90000
like contains the value indicated in the string passed. % can be added anywhere as part of the string to indicate that there can exist text before or after the string parts. In the example, the command looks for a name starting with "Account". This form of search is case sensitive. Note that this method of search will also work: name like "A%t", and this search will yield records with name values beginning with A and ending in t. name like "Account%"
ne not equal to. This search returns records that do not include the value "my_mediator" for the name field. name ne "my_mediator"
notin not in. The current value of the specified field must not be in the specified list. The following example will return records that do not have a status value of "active". status notin ("active")

Field Filtering

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

curl -X GET \
'https://api.carrierx.com/mediator/v1/bindings?exclude_fields=properties' \
-u '[your_user_name]:[your_password]'

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

{
    "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",
            "transformations": [],
            "type": "conference",
            "voip_token": null
        }
    ],
    "limit": 1000,
    "offset": 0,
    "pagination": {},
    "total": 1
}

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

Parameter Data Type Description
include_fields string The comma separated list of fields to be included in the response. The fields depend on the object. See the Object section for that object to see which fields return.
exclude_fields string The comma separated list of fields to be excluded from the response. The fields depend on the object. See the Object section for that object to see which fields return.

HTTP Errors

The Conference API uses the following HTTP error codes:

Error Code Message Description
400 Bad Request The request could not be understood by the server due to malformed syntax. The client should not repeat the request without modifications.
400 No JSON object could be decoded Generally an indicator that there is a syntax error.
401 Unauthorized The request requires user authentication.
401 Bad credentials The request requires correct user authentication.
403 Forbidden The server understood the request, but is refusing to fulfill it. Authorization will not help and the request should not be repeated.
404 Not Found The requested resource was not found on the server.
404 Cannot find item by SID The SID number does not exist. Verify that the SID has been entered correctly. Note that calls can expire.
415 Unsupported media type Ensure that the header includes support for the content type JSON.
500 Internal server error The server encountered an unexpected condition which prevented it from fulfilling the request.

API Reference

The Mediator API has three objects: Bindings, Dialouts, and DIDs. 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.

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 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 goes over the parts of the Binding object. This is the JSON response that gets returned when a request is successful. In this section, there is also information about the optional fields that can be added to further customize bindings.

Attribute Data Type Description
binding_sid string The binding secure ID. This ID can be used to reference and target a specific Binding object.
account_sid string The account secure ID.
attributes nested object The optional fields and values added to a binding. The built-in attributes are listed in the table below.
date_created string The date that the binding was created.
destination_did string This phone number will be reached after the origination_did has called and the redirect_did has forwarded the call. This is the only required field to create a binding. This field accepts phone numbers in E.164 format.
dtmf string If this field is filled, the dtmf sequence will be executed after dialing the destination_did. For example, this field can be set to automatically enter the access code to a meeting, (i.e., “,,,,1357” , which means wait two seconds, then enter “1”, “3”, “5”, “7”). Note that each comma inserted into a dtmf string denotes pausing for .5 seconds.
maximum_ttl integer The number of seconds that the binding will remain active. 3600 is the default value. The value -1 creates an indefinite binding.
name string The name of the binding. If a name is not explicitly assigned to the binding, the value will be set to N/A. Note that this is a friendly name used for internal reference.
origination_did string The calling phone number assigned to the Binding object. If the field is left blank, the binding will apply to calls from any incoming phone numbers. Entering a phone number into the field means that the binding instance will only apply to that specific caller. This field accepts phone numbers in E.164 format.
redirect_did string The DID in this field will be forwarded to the destination_did. DIDs are rented through CarrierX.
wait_origination_did_ttl integer The number of seconds during which an origination_did can be assigned if it has not already been assigned to the Binding object. As long as the origination_did is not yet set (at either the creation of the object or through PATCH or PUT requests), the first incoming phone number will be bound. Enter -1 to disable this feature, and allow the binding to apply to all incoming calls if no origination_did is set. 300 is the default value.

attributes

Below are the additional fields that can be added to further customize bindings. All of these attributes are optional. Custom fields and values can also be added in the same fashion as the other binding attributes are. Add these attributes as a nested object.

Attribute Data Type Description
announce URL The audio file that plays to the caller before they are connected to the second party. File types accepted are wav and mp3.
cnam string The CNAM for outbound calls. Note that this may not be preserved for calls terminated through the PSTN.
fix_anonymous_cid boolean The value of this field will determine whether or not a blocked or unavailable caller ID will be replaced with the redirect_did. This field is similar to hide_origination_did but targets blocked phone numbers only. The value true means that blocked phone numbers will be displayed as the redirect_did phone number.
hide_origination_did boolean The value of this field will determine whether or not to hide the caller’s phone number. Instead, the redirect_did phone number will appear on the caller ID. true is the default value. The value true means that the redirect_did will be displayed instead of the origination_did as the caller. To be able to change the value of this field from true to false, please email support@carrierx.com.
ringback string This field is used to customize what the caller hears while waiting for the destination_did to answer. The value false will disable ringing for the caller, so the caller will hear silence until the destination_did answers. By passing the value moh, the caller will hear hold music. Assigning passthrough as the ringback value defers what the caller hears to the destination_did's behavior.
sip_header_* string The values in this field will be sent as extra SIP headers, added to the SIP invite. The header name must start with X-.

Create Binding

The following POST request creates a new binding. 

curl -X POST \
'https://api.carrierx.com/mediator/v1/bindings' \
-H 'Content-Type: application/json' \
--data-binary '{"destination_did":"15162065338", "attributes": {"ringback":"moh"}}' \
-u '[your_user_name]:[your_password]'

A successful request will return a 200 response code with a serialized copy of the Binding object.

{
  "body": {
    "account_sid": "13e156f7-0d21-4ba6-9e32-c56dc2c6098f",
    "attributes": {},
    "binding_sid": "05561bef-ce48-4823-a847-bf10f7837a42",
    "date_created": "2018-10-09T22:47:56.609Z",
    "destination_did": "15162065338",
    "dtmf": null,
    "maximum_ttl": -1,
    "name": "N/A",
    "origination_did": null,
    "redirect_did": "15162065346",
    "wait_origination_did_ttl": -1
  },
  "status": 200
}

This request creates a new Binding object. destination_did is the only field required to establish a binding. When creating a binding without a binding_did designated, an available DID on the account will be assigned as the binding_did. The request will 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. 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.

Method URL
POST /bindings

Body 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.

Attribute Data Type Description
account_sid string The secure ID of the account to which the dialout belongs.
attributes nested object The optional fields and values added to a dialout. The attributes are listed in the table below. Note that custom fields can be added in the same manner as the built-in attributes.
date_created string The date that the dialout was created.
delay integer The delay before both parties are contacted, in seconds. 0 is the default value.
dialout_sid string The dialout secure ID.
redirect_did string The DID that dials out the stage_one_destination_did and stage_two_destination_did
stage_one_destination_did string The first DID to dial out to.
stage_two_destination_did string The second DID to dial out to.

attributes

Below are the additional binding 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.

Attribute Data Type Description
sip_header_* string The values in this field will be sent as extra SIP headers, added to the SIP invite. The header name must start with X-.
hide_origination_did boolean The value of this field will determine whether or not to hide the caller’s phone number. Instead, the redirect_did phone number will appear on the caller ID. true is the default value. The value true means that the redirect_did will be displayed instead of the origination_did as the caller. To be able to change the value of this field from true to false, please email support@carrierx.com.
fix_anonymous_cid boolean The value of this field will determine whether or not a blocked or unavailable caller ID will be replaced with the redirect_did. The value true means that blocked phone numbers will be displayed as the redirect_did phone number.
announce URL The audio file that plays to stage_one_destination_did before they are connected to the stage_two_destination_did. File formats accepted are wav and mp3.
cnam string The CNAM for outbound calls. Note that this may not be preserved for calls terminated through the PSTN.
ringback string This field dictates what stage_one_destination_did will hear while stage_two_destination_did is being dialed. The value false will disable ringing for stage_one_destination_did, so they will hear silence until brought into the call when stage_two_destination_did answers. By passing the value moh, stage_one_destination_did will hear hold music. Assigning passthrough as the ringback value defers what stage_one_destination_did hears to the behavior of stage_two_destination_did.
use_call_confirmation URL When stage_one_destination_did answers, the use_call_confirmation sound file will play. The default value is null. If the URL is set to an invalid value, the default file will play. A URL can be entered to overwrite the default URL.

Create Dialout

The following POST request creates a new dialout. 

curl -X POST \
'https://api.carrierx.com/mediator/v1/dialouts' \
-H 'Content-Type: application/json' \
--data-binary '{"stage_one_destination_did":"15162065339", "stage_two_destination_did":"15162065338", "redirect_did":"15162065340", "attributes": {"ringback":"false"}}' \
-u '[your_user_name]:[your_password]'

A successful request will return a 200 response code with a serialized copy of the Dialout object.

{
  "body": {
      "account_sid": "13e156f7-0d21-4ba6-9e32-c56dc2c6098f",
      "attributes": {
          "hide_origination_did": "true"
      },
      "date_created": "2018-10-09T20:40:57.675Z",
      "delay": 0,
      "dialout_sid": "15e93c0c-a0eb-4c5d-9b92-f8fd60b2def6",
      "redirect_did": "15162065337",
      "stage_one_destination_did": "15162065339",
      "stage_two_destination_did": "15162065338"
  },
  "status": 200
}

This request creates a new 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.

Method URL
POST /dialouts

Body Arguments

JSON representation of the fields and values of the dialout to be created. Fields required to create a dialout are stage_one_destination_did, stage_two_destination_did, and redirect_did.

To view all fields that appear in the Dialout object, see the Dialout Object.
