Send a Text Message

In this code snippet you will see how to send a Viber message using the Messages API.

NOTE: It is important that you read this information about Viber accounts and messaging before trying this code snippet.

For a step-by-step guide to this topic, you can read our tutorial Sending Viber Service messages with the Messages API.

Example

Ensure the following variables are set to your required values using any convenient method:

Key	Description
`BASE_URL`	For production use the base URL is `https://api.nexmo.com/`. For sandbox testing the base URL is `https://messages-sandbox.nexmo.com/`.
`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.
`VONAGE_APPLICATION_ID`	The Vonage Application ID.
`VIBER_SERVICE_MESSAGE_ID`	Your Viber Service Message ID. For sandbox testing this is 16273.
`TO_NUMBER`	Replace with the number you are sending to. E.g. `447700900001`

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