# Apps

If you want to use the Epicollect5 API to get data for a **private project**, you will have to register your "app" to get authentication details to exchange with the Epicollect5 server.

{% hint style="info" %}
A fully-fledged Developer Guide can be found at [**https://developers.epicollect.net**](https://developers.epicollect.net/)
{% endhint %}

Go to your Apps page under the Developers section:

Click on the "Create New App" button

Give a name to your App and click on "Create"![](https://3293478884-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F32OIF30CgrNUuRY6IjkW%2Fuploads%2Fgit-blob-8c7c7d0bf1d4734e1443cffb3ace10aaa14f099d%2Fapi-6.png?alt=media)"

Now you can use the generated Client ID and client Secret in your script. [Show me how.](https://epicollect5.gitbooks.io/epicollect5-api/content/client-credentials-grant/retrieve-token.html)

**Notice you need to register your app only once for a project** and reuse the Client ID and Client Secret on your applications.
