User API is an interface where you can manage and track usage analytics of the onboarding material for each user of yours. It becomes available when User Identification is enabled successfully.
Once User Identification is enabled and Active, you will be able to access your API Key (API Access Token) in the Installation section.

You can achieve the following by using this API:
Create a user with their own user ID
Add custom attributes to a user
Update custom attributes of a user
Track custom attributes of a user
Track preview history of a user
Reset preview history of a user
Delete user
We recommend you get support from your development team and use an API Development Environment to access this data. Postman is an excellent alternative for this task.
You can use our API Documentation to learn more about utilizing the User API.
