A video’s conversion/transcode status is returned under the “status” field in the “transcode” object of the video response. This field will return the value “complete”, “error”, or “in_progress.”
The Vimeo API does not currently provide a webhook, callback, or push notification when an upload has completed transcoding. Instead, developers will need to periodically make GET requests to the API to get the video's transcode status.
Refer to the FAQ and how to upload videos on Vimeo OTT to learn more about video transcoding.
