RCS capabilities of destination phones

Phone handsets can vary in their RCS capabilities. They might not support RCS at all or only support a subset of possible RCS capabilities. Telnyx API provides two convenient endpoints to query destination handset capabilities.

Single number capability query

curl -H 'Authorization: Bearer ***` \
https://api.telnyx.com/v2/messaging/rcs/capabilities/Agent007/+13135551234


{
"data": {
"record_type": "rcs.capabilities",
"phone_number": "+13125551234",
"agent_id": "Agent007",
"agent_name": "Test Agent",
"features": [
"ACTION_CREATE_CALENDAR_EVENT",
"ACTION_DIAL",
"ACTION_OPEN_URL",
"ACTION_OPEN_URL_IN_WEBVIEW",
"ACTION_SHARE_LOCATION",
"ACTION_VIEW_LOCATION",
"RICHCARD_CAROUSEL",
"RICHCARD_STANDALONE"
],
"status": "Success"
}
}

The URL must have two in-path parameters:

  • RCS agent ID (Agent007 in this example)
  • Phone number (+13125551234 in this example).

Here's a list of possible capabilities:

  • ACTION_COMPOSE
  • ACTION_CREATE_CALENDAR_EVENT
  • ACTION_DIAL
  • ACTION_OPEN_URL
  • ACTION_OPEN_URL_IN_WEBVIEW
  • ACTION_SHARE_LOCATION
  • ACTION_VIEW_LOCATION
  • RICHCARD_CAROUSEL
  • RICHCARD_STANDALONE
  • GENERIC_RCS_FEATURE

Sometimes we are able to determine that a given destination is RCS-enabled, but we cannot determine exactly which features are supported. In such cases we return only GENERIC_RCS_FEATURE:

{
"data": {
"record_type": "rcs.capabilities",
"phone_number": "+13125551234",
"agent_id": "Agent007",
"agent_name": "Test Agent",
"features": [
"GENERIC_RCS_FEATURE"
],
"status": "Success"
}
}

If the destination is not RCS-enabled we return empty or null features:


{
"data": {
"record_type": "rcs.capabilities",
"phone_number": "+13125551234",
"agent_id": "Agent007",
"agent_name": "Test Agent",
"features": null,
"status": "RCS is disabled or agent is not provisioned for the carrier"
}
}

Bulk number query

It is possible to query for RCS capabilities for up to 100 numbers:

curl  -X POST -H 'Authorization: Bearer ***' \
-H 'Content-Type: application/json' \
https://api.telnyx.com/v2/messaging/rcs/bulk_capabilities \
-d'{
"agent_id": "Agent007",
"phone_numbers": ["+13125551234", "+18655551234"]
}'

{
"data": [
{
"record_type": "rcs.capabilities",
"phone_number": "+18655551234",
"agent_id": "Agent007",
"agent_name": "Test Agent",
"features": [
"GENERIC_RCS_FEATURE"
]
},
{
"record_type": "rcs.capabilities",
"phone_number": "+13125551234",
"agent_id": "Agent007",
"agent_name": "Test Agent",
"features": [
"ACTION_CREATE_CALENDAR_EVENT",
"ACTION_DIAL",
"ACTION_OPEN_URL",
"ACTION_OPEN_URL_IN_WEBVIEW",
"ACTION_SHARE_LOCATION",
"ACTION_VIEW_LOCATION",
"RICHCARD_CAROUSEL",
"RICHCARD_STANDALONE"
]
}
]
}

Please note that RCS capability query can be slow.
