Hi Daniele,

In you example you used this structure in your body to get item information or to create a new item:

{

"number": "PostmanItem",

"displayName":"TryOauth20"

}

How did you get this structure? How did you know how to use the structure as the body?

I'm trying to retrieve my SOAP request body. I can see I have a connection and that the API responds, but I can't get information or Post Information.

I took the long road.

I downloaded BC20 Onprem.

in Users there is a webservice key. I made use of this key and a browser extension called "Wizdler" to retrieve the API bodies. This work for now until Microsoft completely removes OData URL and the User webservice keys.
