Developer workflow
No code requiredCompose requests against the real partner API, inspect the exact payload and response, and graduate selected WhatsApp scenarios to controlled live delivery.

ik_test_ key cannot deliver even if a request omits dry_run. That makes the same test key safe in local, preview, and CI environments.Live testing is intentionally narrower than the production API. It requires the portal's global mode to be Live, a connected WhatsApp client, and a phone number added to the sandbox test-number allowlist.

The sandbox uses your partner account, keys, connected clients, and test recipients, so you need to sign in.
