[ SANDBOX MODE ]

Test without side effects.

Use wf_test_ keys to simulate the full API without sending real messages or consuming wallet credits.

No billing impact

Sandbox calls are never charged. Wallet balance is unaffected.

No real sends

Messages log to your inbox tagged [Sandbox] instead of reaching customers.

Same response shape

Every response is identical to production. Ship code that works on day one.
