I have a working example of using a SOAP API call using a simple calculator. So, it’s obvious my call was available at one point in this project. Not sure why it would not available now.
I also tried creating a new project and the same issue comes up, I cannot find how to add my API Call to the workflow. See details below.
I created a calculate button that called the Add API Call defined as shown in this example. But now when I try to add an API action to the workflow using another button, it seems to show that the API Connector plug-in is not available with the call I defined.
See a quick walk through of what was done here
See example project here
Thank you for your help with this!
