How can I call a SAP API with a parameter in the link?


I’m creating a prototype app for Deloitte as an intern and I’ve gotten really stuck for the whole week:

I’m able to create a sales order however attaching an item to it doesn’t work for me. When I want to add an item to it through regular Appgyver data resource selection, it doesn’t seem to work. I need to be able to add a parameter to the url however I don’t know how to alter it. Below are the wrong one and the one it should be.

Wrong URL:

Right URL: ttps://‘1998’)/to_item

Any help would be greatly appreciated, I can also call with someone if it helps (

Thanks in advance
