This authorization mechanism includes obtaining a bearer token from the configured Token URL and then using that token to call Anypoint APIs.

The following steps demonstrate this processing using the Anypoint API

/cloudhub/api/v2/applications

Create a Connected App that acts on its own behalf (to start, add all Runtime Manager scopes). Review Trying to use Connected App of grant type client_credential to call MuleSoft ‘API Platform API’ and getting "Authorization Error" for detailed instructions for creating the Connected App.
Copy the Client ID and Client Secret for the Connected App
In Anypoint Studio, create a Mule Project and add the OAuth module from the Mule Palette
Create an HTTP Request Configuration element and configure Authorization to be "Client credentials grant type"
Configure Client ID and Client Secret to be those values for the Connected App
Configure the Token URL to be https://anypoint.mulesoft.com/accounts/api/v2/oauth/token (NOTE: this is the same URL as called when obtaining a bearer token)
Add a Request operation and configure as shown (NOTE: the Header keys and values must be quotation marks):
