Enter the necessary parameters and click Try It to run the request.

Authentication using Base64 encoding

Note for developers

API requests require authentication using HTTP Basic Authentication with an API key. The API key serves as the username, while the password field should be left empty. The format to encode is: your_api_key: (note the trailing colon).

This string must be Base64-encoded and included in the request's Authorization header as follows:

Authorization: Basic encoded_value

You can generate the encoded value using a trusted Base64 encoder.

Postman collection

Things to know before you start

Authentication: Requires an Event API Key (not User API Key as stated in some documentation).
Response structure: The response is an object where each key is an event name (e.g., app_install) and the value is an array of event data.
Limit: The limit parameter is optional but cannot exceed 50. If no limit is specified, the system default is used.
Event-specific attributes: The data returned for each event includes properties specific to that event type (e.g., an app_install event includes app_name and app_version).
Use case: Best for debugging event tracking, verifying event data, reviewing recent event payloads, and analyzing event properties.
