I created my first proxy api - now I would like to test it. I can't find the URL anywhere, unfortunately. Where can I find it?
Using Apigee X ?
you need to look in the ENVIRONMENT GROUP. You specified a hostname there.
You set up the hostname in Step 7 "Configure Access Routing."
the endpoint for your API will be
https://HOSTNAME/PROXY_BASEPATH
BTW if you don't have a DNS service to establish your own DNS name, you can use https://nip.io/ . It's a free service that automatically maps from names like 182.13.45.12.nip.io into an IP Address. You will use the IP address of your front-end machine.
If you don't know your IP address, visit console.cloud.google.com to find it.
