Send an SMS

In this code snippet you will see how to send an SMS using the Messages API.

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

Delivery receipts

The webhook used for the delivery receipt will depend on the type of authentication used:

Authentication type used	Webhook used for delivery receipt
Basic Auth	account-level webhook is used for delivery receipt.
JWT Auth	application-level webhook is used for delivery receipt / status.

Reception of delivery receipts depends on availability of network support.

Example

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

Key	Description
`VONAGE_APPLICATION_ID`	The Vonage Application ID.
`FROM_NUMBER`	The phone number you are sending the message from.
`TO_NUMBER`	The phone number you are sending the message to.

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