Yes, the Portal APIs (PAPI) is published via an API Portal so we can manage them just like you manage your APIs. The PAPI Portal is located at: apiportal.dev.ca.com and has both your Production and Dev Portal's APIs already published there, as well as documentation/interactive documentation so you can understand how to work with them.
To get an account on the PAPI Portal, please open a Tech Support ticket and supply a list of users and their email addresses.
