Warmup

API endpoint - POST /api/2/img/warmup?auth=[API_SECRET]
/warmup performs transformations and caches them, so it will speed up the first response time from the real user.
The typical usecase is an application where the user can upload images by themselves, then see them once uploaded. The first render could take some time (1-4 seconds) and using /warmup will decrease the response time.
The below example will warm up caches for 2 variants of the image:
https://pixboost.com/api/2/img/http://www.midday.coffee/banner.jpeg/resize?size=x100&auth=ABCDEF
https://pixboost.com/api/2/img/http://www.midday.coffee/banner.jpeg/resize?fit=100x100\&auth=ABCDEF
The URLs of the images to warm up should be exact the same as you use in your front end implementation.
API_SECRET - secret key.
202 - The warmup has been successfully initiated.
You can find reference example of using cache invalidation workflow with S3 bucket here. You can replace cache invalidation call with /warmup in Lambda.
Maximum number of images to warmup in one call is 20. This is a soft limit and could be increased on request.
