How Sandbox Works
Sandbox API keys (prefixed with afk_sandbox_) behave identically to live keys, but they don't send real messages or charge your wallet.
Use Cases
- Testing new integrations before going live
- CI/CD pipelines that need to test messaging flows
- Demos and presentations
- Training new team members
Limitations
Sandbox messages appear as "sent" but are never actually delivered. Delivery callbacks are simulated with realistic delays.
