List workflow hook executions

GET/api/v2/workspaces/{slug}/projects/{project_id}/workflows/{workflow_id}/state-transitions/{transition_id}/hooks/{pk}/executions/

Return the runs of one hook as a paginated list, newest started_at first. Each row records the work item that moved, the run's status, what the handler received, and what it returned.

The history outlives the hook. After you delete a hook, its runs stay readable here. Plane checks only the transition in the path. An unknown hook id returns 200 with an empty list, not 404.

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.

project_id:requiredstring

The project the workflow belongs to. Accepts the project UUID or its bare identifier, for example ENG.

workflow_id:requiredstring (uuid)

The workflow the transition belongs to.

transition_id:requiredstring (uuid)

The transition the hook is attached to. An unknown transition returns 404.

pk:requiredstring (uuid)

The id of the hook, including a deleted one.

Pagination

The order is fixed, newest started_at first. The phase, handler_name, is_enabled, and order_by parameters that the hook list takes have no effect here.

per_page:optionalinteger

Page size. Defaults to 50, maximum 200.

offset:optionalinteger

Number of rows to skip from the start of the result set. Read the next value from the response rather than computing offsets yourself.

count:optionalboolean

Defaults to true. Set to false to skip the COUNT(*) behind total_count. The field is then omitted from the response.

Response shaping

fields:optionalstring

Comma-separated list of fields to return on each row. Unrequested keys are omitted from the response, not returned as null, so absent means "not requested" and null means "actually null". id always comes back whether or not you name it.

Pass all for every requestable field. An unknown name is a 400 that lists the valid set and suggests the closest match, so a typo can't silently cost you the saving.

Requestable here: completed_at, error_message, id, input_data, output_data, started_at, status, work_item_id.

See Sparse fields.

Scopes

The execution object

Field	Type	Meaning
id	string (uuid)	Unique identifier for the run.
work_item_id	string (uuid)	The work item whose move triggered the run.
status	string	One of pending, running, success, or failed.
started_at	string (date-time)	When the run started. null while pending.
completed_at	string (date-time)	When the run finished. null until it does.
input_data	object	What the handler received. For send_webhook: url_host, event_type, and phase. For run_script: the transition event passed to the script.
output_data	object	What the handler returned. For send_webhook: delivery_id, status_code, response_body, duration_ms, and error. For run_script: the script's output.
error_message	string	Why the run failed, for example HTTP 503 for a webhook that got a non-2xx response. Empty when it succeeded.

A failed pre run blocks the transition. A failed post run is recorded here, and the move it followed stands.
