Cache Purging
When a purgeApiKey is configured, the plugin automatically purges the Imgix cache when assets are saved, moved, replaced, or deleted.
Purge jobs are added to the Craft queue at priority 9 (higher than Blitz at priority 10).
Getting an API Key
To enable purge functionality, create an API key in the Imgix dashboard and set it as the purgeApiKey config value or the CRAFT_IMGIX_PURGE_API_KEY environment variable.
