Sources
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.

}Authorizations
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 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
Cursor from the previous page's next_cursor.
Required string length:
1 - 4096Connections per page.
Required range:
1 <= x <= 200Was this page helpful?
