smartphoneEmbedded Signup Sandbox

Test with simulated WABA credentials

Use the sample WABA ID and WABA number produced by the Embedded Signup simulation. Sending here never calls the real WhatsApp API.

scienceSimulation onlySample credentials are stored locally in this browser.
Edit the documented request body, then test it in the phone preview.
