#### Configuring credentials in Refold

App settings page lets you configure the authentication settings for an `OAuth 2.0` based application. For your customers to provide you authorization to access their data,
they would first need to install your application. This page lets you set up your application credentials.

Provide the acquired Client ID and Client Secret under Settings of the app and save it.

#### Configuring Scopes

Refold lets you configure what permissions to ask from your users while they install your application. The scopes can be added or removed from the App settings page, under `Permissions & Scopes`
section.

For some applications Refold sets **mandatory scopes** which cannot be removed. Additional scopes can be selected from the drop down. Refold also has the provision to add any
custom scopes supported by the respective platform.

Once the scopes has been added to the application in Refold, the app will now request for access of the mentioned scopes.

<Warning>
  If you are facing scopes missing or invalid scope error. Make sure you are not passing any custom scope not supported by the platform.
</Warning>
