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 |
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. |
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.
