Has anyone had success in writing a Nintex Xtension (in NAC / Nintex Automation Cloud) that goes through your Nintex Gateway to access your internal Web API endpoints?


We are trying to set this up and getting some errors, probably something with our Swagger / JSON configuration file that is not right.  All we get is this generic error,


Received an error response from the connector: Invalid Xtension URL: . [Error Code: IO.XtensionExecute.ErrorResponse]


Maybe we could compare our Swagger files to see what is different.

I did a test back in February with one of our internal web APIs and confirmed that it worked. How the JSON file would need to be setup would obviously depend on the requirements for the API you’re trying to call internally.

Follow-up - I found the solution. I added some “security” nodes to the JSON file to allow for Basic authentication.  This helped us get the workflow actions to work.  But I am still having trouble using this on the Nintex Form in the Data Lookup control.  I will be posting another question about that.
