@dosubot[bot] commented on GitHub (Oct 27, 2025):

In Dify v1.9.2 (self-hosted), you cannot directly call the workflow knowledge base pipeline via a single API request. The official API supports initializing knowledge bases and running pipelines for standard (non-workflow) knowledge bases, but workflow-integrated knowledge bases are managed differently and do not expose the same API endpoints for pipeline execution. There is no unified API call that both uploads a file and triggers the full pipeline for workflow knowledge bases—API automation requires multiple steps and may not fully replicate UI behavior, especially for custom pipeline steps. This is a known limitation and is not a bug, but rather a current design constraint of the platform. For now, the most reliable way to trigger workflow knowledge base pipelines is still through the Web UI, not via API requests reference.

To reply, just mention @dosu.
