How to create a PowerApp Costum Connector from Import a Postman Collection

I want to describe in much detail my scenario to explain what I want to do:

  1. We have an installation of Dynamics 365 Business Central on premise that exposes a local web service SOAP locally (not reachable from internet)

  2. From Postman site with postman agent installed locally we are able to consume the web service soap

Is there a solution to use the same call from Power App custom connector to your postman collection?

We try to export the web service collection from Postman to Power App but operation fails.

I send to you screenshot where you can see:

  • collection created
  • result of collection imported with hostname problem
  • call not imported correctly

Can we have a call to clarify this aspect?
