Configuring credentials in Cobalt
App settings page lets you configure the authentication settings for an OAuth2
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.
Cobalt lets you use pre-configured applications to play around. You can do so by selecting Use our credentials
. However, if you wish to use your own application,
select Use your own credentials
. Provide the aquired Client Id and Client Secret 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 Slack App Dashboard and update the scopes as added on Cobalt.
Navigate to Your Apps
> Select the OAuth App created for Cobalt > Click on OAuth & Permissions
under Features in the left menu > Scroll down to the Scopes
section > Add the scopes as added in Cobalt by clicking Add an OAuth Scope
and select the scope.
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.
