Trying to get the connector to work. I have been entering the username and password under the HTTP Basic Auth setting. It keeps coming up with an error. If I “Manually enter API response” the calls will show up in the editor but the API will not show up under add external API.
From the screenshot it seems that there is an issue with the certificate of the API you are trying to connect to.
Once that is resolved it should be smooth sailing from there on.
