POST /editing/image/process/get

API reference for the "/editing/image/process/get" endpoint.

If an editing extension supports remote image processing, it's not always possible for the extension to process the user's image on the server before the request times out. (The current timeout duration is 30 seconds for China and 15 seconds for the rest of the world.)
In these cases, the /editing/image/process can initiate polling. Canva then repeatedly sends POST requests to the following endpoint for up to 60 seconds:
<base_url>/editing/image/process/get
The purpose of these requests is to check if the image processing task is complete. Once it is, the remoteProcess method returns the user's processed image.
Notes
When sending this request, Canva replaces <base_url> with the extension's Base URL. You can configure the Base URL via the Developer Portal.
