Warmup API

Warm-up allows you to proactively cache your images in the Cloudimage infrastructure for faster processing upon first request from your end users. We recommend to warm-up Cloudimage if you deliver a large amount of new images (few tens of thousands) or if you have images with less than 10 views in order to experience the best performance globally.

Creating a warmup task

You can provide a list of your images either in the request body or in a txt/csv file.
