Messaging - Send link button with RCS

This page walks you step-by-step through how to use Telesign Messaging to send an RCS message to an end-user that includes a link button to a URL of your choice.

Before you begin

Make sure you have the following before you start:

  • Transaction Callback Service: You need to have this set up so Telesign can send you delivery status updates for your Messaging requests. See Messaging - Callback service for more details.
  • RCS account details: Before sending a message using RCS, you first need to work with our Customer Support Team to set up an RCS account for you. See Set up RCS for your account for more details.



Currently RCS is not supported by iOS devices. We recommend either ensuring your end users have supported devices or including a fallback channel for iOS users.


  1. Send a POST /v1/omnichannel request. Include the following param values:
channelsarray of channel objectsAdd channel objects to the array in the order you want the service to try the channels.yes
channels[0]{"channel":"rcs"}Include rcs as the first channel.yes
channels[0].fallback_timeA time in seconds.Specify the time to wait before cascading to the next

message.rcs.parameters.url_idAn identifier.A unique ID for this link.yes
message.rcs.parameters.url_textSome text.Text to display inside the link button.yes

  1. If the send in RCS format is successful, your end-user receives a message on their device that looks like this.

RCS Message

  1. If the send in RCS format fails, the service tries to send the next specified backup channel (if any).

SMS Backup

  1. Updates on the status of this message are sent to the callback URL for your Transaction Callback Service. The general callback schema common to both this and other products is described on Transaction Callback Service. Modifications to the callback schema for this product are described on Messaging - Callback service. Search for these callbacks based on the reference ID in the response to your original Messaging request. Each callback payload includes an object with the status of the send for each channel that is tried.

Callback Example

GET /callback_endpoint HTTP/1.1
  "reference_id": "35C8B5D509BC10689196FED2AD551B8A",
  "external_id": "null",
  "status": {
    "code": 3000,
    "description": "Delivered",
    "last_channel": "sms",
    "updated_on": "2020-05-04 22:07:01:226"
  "channel_status": [
    {"rcs": {
      "code": 3056,
      "description": "Message failed to deliver in specified fallback time",
      "reference_id": "65C77D4A6C5C09085694EFB6C554D2BF",
      "updated_on": "2020-05-04 22:05:00.325"
    {"sms": {
      "code": 3000,
      "description": "Delivered",
      "reference_id": "65C77D4A6C5C09085694EFB6C558B4C7",
      "updated_on": "2020-05-04 22:07:01:226"



In addition to the reference ID for the Messaging transaction itself, the delivery status payload also includes a reference ID for the message-send on each channel. These can be useful for troubleshooting purposes.
