Send a RCS Suggested Action (View a Location) Message

In this code snippet you learn how to send a RCS Suggested Action message using the custom message type of the Messages API RCS channel. This message will prompt the recipient to view a location in their device's default map application.

For more information on RCS Messaging see Understanding RCS messaging
For a detailed guide on the custom message type see RCS Custom Messages

Example

Find the description for all variables used in each code snippet below:

Key	Description
`VONAGE_APPLICATION_ID`	The Vonage Application ID.
`VONAGE_PRIVATE_KEY_PATH`	Private key path.
`MESSAGES_API_URL`	There are two versions of the API, each with their own endpoints. For production the previous Messages API endpoint was `https://api.nexmo.com/v0.1/messages`, the new one is `https://api.nexmo.com/v1/messages`. For sandbox testing the Messages API endpoint is `https://messages-sandbox.nexmo.com/v0.1/messages` or `https://messages-sandbox.nexmo.com/v1/messages`, depending on which version you have set in the sandbox dashboard.
`JWT`	Used to authenticate your request. See Authentication for more information, including how to generate a JWT.
`TO_NUMBER`	The number you are sending the RCS message to in E.164 format. For example `447700900000`.
`RCS_SENDER_ID`	The sender ID for the RCS message.

NOTE: Don't use a leading + or 00 when entering a phone number, start with the country code, for example 447700900000.
