If you get status code

Retry-After header, where you will see a number displayed. This is the amount of seconds that you need to wait, before you can retry sending your requests.
A successful request will return a
202 ACCEPTED response code.
When the image has been provided, we forward it on to our transcoder service in order to generate the three sizes provided in the playlist’s images object. This operation may take a short time, so performing a GET request to the playlist may not immediately return URLs to the updated images.
On error, the header status code is an error code and the response body contains an error object.
