Trying to register webhook endpoint https://mydomain.network/authorize-net-callback
receiving an error from both the portal interface and REST endpoint:
Error: Invalid url entered. Only valid HTTP(s) urls are supported.
When I switch the endpoint to mydomain.NET/authorize-net-callback it completes successfully. I think there is an issue with the validation where .network is not being accepted as a valid domain. Help!
So the issue here is that currently the supported URLs domain can only be of size 2-6 characters.
If you can try getting such a domain, that will let you register an endpoint. Otherwise, you can raise a request to increase the character length for a webhook endpoint here: https://community.developer.authorize.net/t5/Ideas/idb-p/ideas
Hope this helps!
