Send a Location

In this code snippet you learn how to send a location to WhatsApp using the Messages API. This uses Vonage's Custom object feature. Further information on the specific message format can be found in the WhatsApp developers Location message documentation.

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`

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