Before you begin

What are Code Snippets?

Code snippets are short pieces of code you can reuse in your own applications. The code snippets utilize code from the Vonage Node Code Snippets and Vonage Curl Code Snippets repositories.

Please read this information carefully, so you can best use the code snippets.


  1. Create a Vonage API Account
  2. Install Node JS - required for using the Vonage Command Line Interface (CLI).
  3. Install the Vonage CLI
  4. Install or update the Beta version of the Node Server SDK - only required if using Node.
  5. Configure webhooks.
  6. Know how to write a webhook server
  7. Know how to test your webhook server locally

Replaceable variables

Generic replaceable

The following replaceable information depends on the library and specific call:

Key Description
VONAGE_API_KEY Your Vonage API key (see it on your dashboard).
VONAGE_API_SECRET Your Vonage API secret (also available on your dashboard).
VONAGE_APPLICATION_ID The Vonage Application ID.


All phone numbers are in E.164 format.

Key Description
VONAGE_NUMBER Your Vonage Number. E.g. 447700900000
TO_NUMBER Replace with the number you are sending to. E.g. 447700900001
FROM_NUMBER Replace with number you are sending from. E.g. 447700900002

Specific replaceable/variables

Some code snippets have more specialized variables, such as Facebook Page IDs, that will need to be replaced by actual values. Where required, these are specified on a per-code snippet basis.


The main ones you will meet here are:

  • /webhooks/inbound-message - You will receive a callback here when Vonage receives a message.
  • /webhooks/message-status - You will receive a callback here when Vonage receives a message status update.

If you are testing locally using Ngrok you will set your webhook URLs in the Vonage Application object using a format similar to the following examples:


Change demo in the above with whatever Ngrok generates for you, unless you have paid for a reusable URL.
