Plug the API into the manager

Take advantage of the magic: operations

• Adding operations enables built in tools

“Products”

• You have to add your API to your products

Now subscribe to the Product

• Users have to subscribe to products, to get access to API’s• Administrators are auto subscribed

Developer Portal

• We can test our api from the developer portal

• Upper right of admin panel
