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

Find the description for all variables used in each code snippet below:

Key	Description
`VONAGE_APPLICATION_ID`	The Vonage Application ID.
`VONAGE_APPLICATION_PRIVATE_KEY_PATH`	Private key path.
`VONAGE_PRIVATE_KEY_PATH`	Private key path.
`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.
`WHATSAPP_NUMBER`	The WhatsApp number that has been allocated to you by Vonage. For sandbox testing the number is 14157386102.
`VONAGE_WHATSAPP_NUMBER`	Refer to `WHATSAPP_NUMBER` above.
`VONAGE_NUMBER`	Refer to `WHATSAPP_NUMBER` above.
`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.
