Configuring credentials in Cobalt

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

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

Once the scopes has been added to the application in Cobalt, go to your Microsoft Azure account and update the scopes as added on Cobalt.

Select the OAuth App created for Cobalt and follow Step 8 and 9 above.

If you are facing scopes missing or invalid scope error. Make sure you are not passing any custom scope not supported by the platform. And, the scopes selected here are identical to the ones selected in the platform.

​
Actions and triggers

Once the above setup is completed, you can create orchestrations of your use-cases using Microsoft Defender actions and triggers. Following are the set of Microsoft Defender actions and triggers supported by Cobalt.
