You can browse early access documentation for the new Events and Profiles APIs:
- Using the Events API - https://develop.zendesk.com/hc/en-us/articles/360001844267
- Using the Profiles API - https://develop.zendesk.com/hc/en-us/articles/360002114927
Along with the Custom Objects API, the Events and Profiles APIs are part of the Sunshine platform. The Events API lets you monitor the activity of users in an application or a system. The Profiles API lets you assemble, create, and track complete customer profiles across growing and disparate systems, data sources, and time periods.
Both APIs are in early access. Signing up to the User Events API early access program also gives you access to the Profiles API.
