Knowledge bases

Update knowledge connector

Update connector source configuration, schedule, or active state. Replacing source configuration on a runnable connector queues an immediate synchronization; paused connectors retain the change without synchronizing until resumed. Source configuration cannot be replaced while synchronization is already in progress. Authentication material cannot be changed through this operation. Workspace API keys return `403`; use a personal API key or scoped OAuth token. OAuth scope: `api:write`.

PATCH/api/v2/knowledge/{knowledgeBaseId}/connectors/{connectorId}

Update connector source configuration, schedule, or active state. Replacing source configuration on a runnable connector queues an immediate synchronization; paused connectors retain the change without synchronizing until resumed. Source configuration cannot be replaced while synchronization is already in progress. Authentication material cannot be changed through this operation. Workspace API keys return 403; use a personal API key or scoped OAuth token.

OAuth scope: api:write.

Authentication

Send a personal or workspace API key in X-API-Key. See key types and access; operations that reject workspace keys say so in their description.

Send X-API-Key in the request header.

Alternatively

Send a Sim OAuth access token in Authorization: Bearer. See OAuth authentication and scopes.

Authorization: Bearer YOUR_ACCESS_TOKEN

Required scopes: api:write
