This is a concise reference of API endpoints applicable for use with sections defined as API sections. The endpoints are the same ones as the Experience APIs for sections and apps listed in the main API reference, but some attributes behave differently.
Detailed guides for each endpoint are available on the Support site.
API-only implementation refers to sections defined as the API type, which work with the API Campaigns Experience OS app. If you are working with Experience Web, even if you only do API campaigns, this is not your implementation type.
