How can I insert an API Body when connecting to API as data source?

[VFXPro]

I'm trying to connect to UPS Quantum View API.  It works well via POST MAN but I'm not getting data from Power BI since it requires my ups login information in the body of the API call.

Body from PostMAN

Current connection to the API in Power BI, but missing the body from above.  How can I insert it and where do I paste it?  I don't understand the syntax required to insert the body into Power BI.  There are no clear instructions anywhere that I can find...  

Thanks for your guidance.  MS has to improve this process to truly make Power BI accessible for more people.

Hi Pat,

I had already look at those articles before coming to this forum and unfortunately, they don't provide much help.  Also, I'm not a developer.  I posted a screenshot to better show what is going on. I pasted the body I'm using from Postman into Power BI advanced editor and I'm not having any luck  Most likely a syntax/formatting problem.  I just don't know where to insert the text string highlited in yellow in the image below.  I'm baffled as to why MS doesn't make Power BI easier to connect to APIs since it's supposed to help "low code" or "citizen developers" to get to data soures.

Hopefully, some can tell where to move that text string or provide guidance on the syntax required.
