# Intro

Epicollect5 provides an API to fetch data programmatically using some simple GET requests.

Responses are in `JSON` (default) or `CSV` format.

For simple uses, we provide you with the parameters and some pre-made endpoints to view in your browser (**public projects only**). [**More info**](/developers/api.md)**.**

**The Client Secret must not be shared!**
