Processing API
API
Set of endpoints that handle file transformations, conversions, and other processing operations on uploaded files.
Architecture
The Processing API is unique in that it’s not a traditional REST API with discrete endpoints. Instead, it operates through a declarative, URL-based syntax where transformations are defined by chaining processing tasks directly in the URL path.
