Extract data via json "analyticsReportResults"

Content

I am not able to extract data from a report using REST json.
Can someone help me?

Attached is the definition and result of the report.

I understand very little of REST and after consulting the documentation I did not make much progress.

The last url I tried was the following (using Postman software):

https: // (myUser): (myPass) @ (mySite) --tst2.custhelp.com/services/rest/connect/v1.4/analyticsReportResults/ (idReport)

* Header *
Key: OSvC-CREST-Application-Context
Value: header

* Body *
Key: lookup
Value: tst

The result of this call using "POST" was a syntax error.
