Sample proxy to use Service account impersonate deployed to apigee and call 3rd party application

[aramkrishna6]

Hi,

If we have a service account and 3rd party target application to apigee only accepts service account impersonate as indicated in

Create short-lived credentials for a service account | IAM Documentation | Google Cloud

Do we have any sample apigee proxy to refer which will list the service account deployment to apigee and invoke any 3rd party application.
