You must add an API proxy in Apigee.
This task only applies if you want to add OAuth authentication to the API proxy in Apigee. If you don't want to add an OAuth flow, proceed to Attaching the PingAuthorize Shared Flow to API proxies.
Note:
These steps reference the Apigee Edge documentation. As you proceed, use values that correspond to you and your Apigee environment instead of the suggested example values. If needed, consult the Apigee X documentation.
