Method : POST

Authorization tab: 
             Type : Basic Auth 
             UserName :  ABCD
             Passsowrd : Test@1234

Body Tab : 
           Selecting  "application/x-www-form-urlencode" Radio Button

Answer 1

Before trying the below code give yourself some time to look here .

Also application/x-www-form-urlencoded has its POST variables stored as key-value pairs in the body.

given().auth().basic(username, password)
.header("Content-Type","application/x-www-form-urlencoded")
.formParam("grant_type", "client_credentials")
.formParam("scope", "ABCDpi")
.post("https://ABCD.KLM.id.XYZ-Cloud.net/oauth2/access_token?realm=PQR")
.then().contentType("").statusCode(200);

Answer 2

I was seeing your code problem with a problem like yours. And I think discovering one solution for our problems. It might work if you change the follow lines:

.body("[{\"grant_type\":\"client_credentials\"}]")
.body("[{\"scope\":\"ABCDpi\"}]").when()

for this:

.body("grant_type=client_credentials&scope=ABCDpi")

I hope having being helpfull.
