Poll it until `run_state` is `completed` or `failed`. Only the API key that requested the deletion can read its job. The job stays readable after the deletion completes. [Get Document File](/en/api-reference/documents-and-chunks/get-document-file) or [Get Source](/en/api-reference/sources/get-source) answers `404` for the deleted object from the moment the deletion is accepted. When a source is deleted with `documents=keep`, its documents are hidden while the job runs and come back when it completes, with `source_id` set to `null`. If the job fails, they stay hidden. A failed deletion cannot be retried over this API. For the deletion flow, see [Delete Documents and Sources](/en/api-reference/guides/knowledge-base#delete-documents-and-sources). ## OpenAPI ````yaml /en/api-reference/openapi_service.json get /knowledge-fs/spaces/{knowledge_base_id}/deletion-jobs/{deletion_job_id} openapi: 3.0.1 info: description: >- REST API for Dify applications and knowledge bases.
