Use this endpoint after you create a Runway reverse-format task. It is the main polling step for /runway/pro/* workflows.

​
Check these fields first

  • Outer code and message for wrapper-level status
  • data.status and data.progress for task progress
  • Nested data.data for provider-side task metadata
  • Final asset fields such as video_url, poster, or related provider output when the task completes

​
Polling pattern

1

Create the reverse-format task first

Start with a reverse-format Runway page such as Generate, Image-to-Video, Video to Video Style Redraw, or Act-one Expression Migration.
2

Retry once if the task is not visible yet

Fresh task ids can briefly return task_not_exist. If that happens, wait a few seconds and poll again.
3

Continue polling until the task is terminal

Keep checking this endpoint until the wrapper status leaves queued or in-progress states and the provider metadata includes a usable output URL.
Live validation on 2026-03-13 confirmed that a fresh Runway task id first appeared through this endpoint after a short delay and then returned a wrapped payload with code: success and data.status: QUEUED.
