PowerApps - HTTP - XML - PowerApps



I'm having trouble determining how to hit an on-prem web service that only responds with XML.


  • On-prem Web Service, Serving XML
  • I can hit the URL in my browser, pass it a single value (ex: "1234") and get a response
  • Example URL:
  • Example Response:
    • <Model xmlns:i="" xmlns="">

Since this is an on-prem endpoint WITHOUT authentication, JSON, request body, or a response body, I'm having trouble figuring out where to start. If it HAD these items, I'd start with a Custom Connector in PowerApps, then a Flow.

But that doesn't work here, no Custom Connector possible. So starting with Flow, I can't even get the HTTP Request setup! I'm only passing a SINGLE VALUE, there are not headers or body parameters to input. Can't figure out how to hit the On-Prem Data Gateway here either. 


Any ideas for me to get started?

Thank you

Hi @ericonline,


It seems that you are trying to connect to custom on-premises APIs, please check the following doc for a reference:

Connect to custom on-premises APIs using data gateway

In addition, please check if the following blog would be helpful for you:

Define HTTP Authentication

Hi @v-yamao-msft and thank you for the resources. I was not able to find a solution in those blog posts. We already have a data gateway setup, I have it selected in the Custom Connector but don't see a way to call the Custom Connector in the HTTP call.

Any further ideas?

Did you ever find a solution?

Looking for an answer on this to please!
