Complete guides and API documentation for integrating and using Fusion Calling's AI voice automation platform.

Documentation FAQ

What can I build with the Fusion Calling documentation?

The docs cover everything you need to integrate and run AI voice agents: the External Calendar and Leads APIs, authentication, webhooks, agent configuration, lead management, SMS messaging, and the admin section.

How do I authenticate API requests?

Every API request is authenticated with a bearer token as documented in the API Reference. Webhooks push call outcomes, lead events, and transcriptions to your endpoints so you can sync them into any CRM.

Does Fusion Calling support white-label resellers?

Yes. Agencies can resell AI voice agents under their own brand using the white-label program, bringing their own Vapi, Retell, or ElevenLabs keys and managing unlimited client sub-accounts from one dashboard.
