List Source Connections

Lists the connections of this knowledge base, oldest first. Pass a connection’s id as connectionId to Create Source to add a source that reads through it.

The list holds a connection only after a source from that provider has been added to the knowledge base in Dify. To use a new provider, add its first source in Dify. Each knowledge base has its own connections. Pick one whose status is active and whose provider_id and configuration match the provider and credential you want.

For the steps to add a source, see Add a Source.

get/knowledge-fs/spaces/{knowledge_base_id}/source-connections

Authorization

Authorizationstringheaderrequired#

Every request authenticates with an API key: Authorization: Bearer {API_KEY}. App endpoints take an app API key; knowledge endpoints take a knowledge base API key (Get Started).

Keep keys server-side; never embed them in client code. Requests with a missing or invalid key fail with HTTP 401 (unauthorized).

Path parameters

knowledge_base_idstringrequired#

Knowledge base ID: the last segment of the Service API endpoint shown in the knowledge base's API Access dialog (…/knowledge-fs/spaces/<knowledge base ID>), and the segment after /datasets/new/ in the address bar.

Query parameters

cursorstring#

Cursor from the previous page's next_cursor.

Length: 1–4096

limitinteger#

Connections per page.

Default: 50

Range: 1–200
