Auth methods (6 types)

Method	Description
No Auth	No authentication required. For public APIs.
Basic Auth	Username/password pair encoded as Base64 in Authorization header.
Bearer Token	Token sent in Authorization header as Bearer {token}.
API Key	Key sent in a configurable header (e.g., X-API-Key).
OAuth 2.0	User authorizes via app's login screen. Fastn manages token refresh automatically.
Custom	Custom handler for proprietary auth flows.

Multiple auth methods can be added to one connector. One is set as default.

Fastn-managed OAuth Apps

For supported platforms, Fastn manages OAuth on your behalf (Settings → OAuth Apps). You can authenticate connectors without creating your own OAuth application in the third-party's developer portal.

Build with AI

Click "Build with AI" on the Connectors page to open the Connector Agent. Describe what you want to connect and the agent:

1. Researches the API

2. Discovers the spec (OpenAPI/Swagger/Postman)

3. Builds actions and events

4. Tests against real connections

5. Fixes failures automatically

Capability registry

Each connector declares capabilities:

• Entities — data types it works with (contacts, orders, products)

• Actions — operations per entity (create, read, update, delete, list)

• Events — webhook events per entity (created, updated, deleted)

Used for connector matching, field coverage analysis, and MCP dynamic tool generation.
