When to use it

Cleanup – remove outdated documents
Right-to-deletion – fulfill GDPR/privacy requests for specific items
Reprocessing – delete then re-ingest after changing metadata schema or content

For removing user memories, use DELETE /memories/delete_memory. To remove an entire tenant, use DELETE /tenants/delete.

This operation is irreversible. Deleted sources cannot be recovered.

Endpoint

Auth: Bearer token
Idempotency: Re-sending a previously-deleted ID returns deleted: false for that item, but the request as a whole still returns 200.
Async: No

Why POST and not DELETE? This endpoint accepts a JSON body with an array of IDs. Some HTTP infrastructure strips bodies from DELETE requests, so HydraDB uses POST to ensure the bulk payload is reliably transmitted.

Example

curl -X POST 'https://api.hydradb.com/knowledge/delete_knowledge' \
  -H "Authorization: Bearer <your_api_key>" \
  -H "Content-Type: application/json" \
  -d '{
    "tenant_id": "my_first_tenant",
    "ids": ["doc_12345", "doc_67890"]
  }'

const response = await client.data.delete({
  tenant_id: "my_first_tenant",
  ids: ["doc_12345", "doc_67890"]
});

response = client.data.delete(
    tenant_id="my_first_tenant",
    ids=["doc_12345", "doc_67890"],
)

Request parameters

Name	Type	Required	Description
`tenant_id`	string	Yes	The tenant the sources belong to.
`ids`	string[]	Yes	One or more `source_id` values to delete (minimum 1).
`sub_tenant_id`	string	No	Sub-tenant scope. If omitted, the default sub-tenant is used.

Response

{
  "success": true,
  "message": "Delete completed",
  "results": [
    {
      "id": "doc_12345",
      "deleted": true,
      "error": null
    },
    {
      "id": "doc_67890",
      "deleted": false,
      "error": "Source not found"
    }
  ],
  "deleted_count": 1
}

Field	Description
`success`	`true` if the request was processed (regardless of per-item outcomes).
`results[]`	One entry per requested ID.
`results[].id`	The source ID that was processed.
`results[].deleted`	`true` if the source was found and deleted, `false` otherwise.
`results[].error`	Error message if `deleted: false`.
`deleted_count`	Total number of sources successfully deleted.

Behavior notes

Partial success is possible. A request can return success: true while some individual items fail. Always inspect results[] to confirm each deletion outcome – don’t rely on the top-level success flag alone.

Cascade scope. Deleting a knowledge source removes its chunks, embeddings, and any graph entities/relations exclusively associated with it. Entities shared with other sources are retained.

Browse before deleting: List data – confirm what you’re about to remove
Delete a single memory: Delete memory
Delete an entire tenant: Delete tenant
