1. Find an API in the catalogue.
  2. Select the API name to open its details.
  3. Select Subscribe.
  4. Enter a name for your subscription. You can create multiple subscriptions for the same API—either to different environments or even to the same one.
  5. Enter a justification for your subscription.
  6. Enter an OAuth Redirect URL for authentication. To add more than one, separate each URL with a semicolon. You can update this later using the Change link.
  7. Select Create subscription to submit your request. Or select Return to API to cancel.

If the API environment requires review and approval before activation, you’ll see a message letting you know.
