In API Marketplace, you create an app to generate an API key and secret for an API product(s). Once you create an app, you can edit it (e.g., to update the name or adjust the products the app covers), or delete it if you no longer need it.
In the Product section, click the checkbox next to the API(s) you want to use with your app.
Click Add App.
API Marketplace creates the app, sends a request to the API team, and sets the status to Pending Approval. Once the API team approves your app request, API Marketplace changes the status to Approved. (If your request is denied, API Marketplace shows a status of Declined.)
