Confirm a workspace asset upload

PATCH/api/v2/workspaces/{slug}/assets/{pk}/

Confirm the upload of a workspace asset, a file uploaded against a workspace. This is the third of three upload steps: create the upload, send the file to storage, then call this endpoint with the asset id. Like any PATCH, it updates the asset: send only the keys you want to change. Omitted keys keep their current value, and an explicit null clears a nullable field.

Path parameters

slug:requiredstring

The workspace slug. It appears in your Plane URLs. In https://app.plane.so/my-team/projects/, the slug is my-team.

pk:requiredstring (uuid)

The asset id.

Response shaping

fields:optionalstring

Comma-separated list of fields to return. Fields you don't request are left out of the response instead of coming back as null. id is always included. Pass all to get every requestable field. An unknown field name returns 400. See Sparse fields.

Requestable here: asset_url, attributes, content_type, created_at, created_by_id, entity_type, external_id, external_source, id, is_uploaded, name, size, updated_at, updated_by_id.
