You can configure the following options to add your oauth application.

1. Enter the **name** of your oauth application.
2. **Define redirect URLs** where authorized users can be redirected to.
3. Check if the application will be used **confidentially**.
4. Choose **client credential flows** and define a user on whose behalf requests will be performed.
5. Press the blue **Create** button to add your oauth application.

## Oauth endpoints

The authentication endpoints are at

* Auth URL: `https://example.com/oauth/authorize`
* Access Token URL: `https://example.com/oauth/token`

## Performing request to the OpenProject API with OAuth token

The following CURL command fetches all projects from the API V3:

`curl --location --request GET 'https://example.com/api/v3/projects' --header 'Authorization: Bearer <your-access-token>'

## Using Postman with oauth?

Set redirect URLs to `urn:ietf:wg:oauth:2.0:oob` in both, for your application (see step 2 above) and 
within Postman.

In Postman the configuration should look like this (Replace `{{protocolHostPort}}` with your host, 
i.e. `https://example.com`)
