Sandbox
Paste a key, pick a template, send a real message. Every request on this page is made by your browser straight to the API, so what you see working here is exactly what your backend has to send.
Your API key
Held in this tab and nowhere else. Not stored, not sent anywhere but the API.
Send from
Which of your WhatsApp numbers the message leaves from.
Choose a template
Only approved templates can be sent. This list is the same one GET /v1/templates returns.
Fill it in
The variables, the file if the header needs one, and who it goes to.
Send it
One request, one message, one credit.
