Hello,
I am trying to set up an API connection point
I am very new to this and the only method I am familiar with is creating an API suite in ION API gateway and uploading a swagger to make the endpoints testable and accessible in ION desk.
The ones whose endpoint it is claim they don't have any swagger, or other documentation i can use. Right now i am unable the access the endpoint in ION desk to set up the connection point and then data flow. No options show up here:

Is there another way to make the endpoint accessible in ION desk, or is there another method altogether i could use?
The only info I have from them is the actual endpoint to post to. We are using HTTPS POST with basic authentication.
This is in an on-prem environment.
Any help is very much appreciated!
