Send a Video Message

In this code snippet you learn how to send a video message through WhatsApp using the Messages API. For WhatsApp the maximum outbound media size is 64MB.

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`	For production use the Messages API endpoint is `https://api.nexmo.com/v0.1/messages`. For sandbox testing the Messages API endpoint is `https://messages-sandbox.nexmo.com/v0.1/messages`.
`WHATSAPP_NUMBER`	The WhatsApp number that has been allocated to you by Vonage. For sandbox testing the number is 14157386170.
`TO_NUMBER`	Replace with the number you are sending to. E.g. `447700900001`
`VIDEO_URL`	The link to the video to send. WhatsApp supports `.mp4` and `.3gpp`. Note, only `H.264` video codec and `AAC` audio codecs are supported.
`VIDEO_CAPTION`	The text describing the video being sent.
