//Set API’s Body
builder.setBody(apiBody);

//Setting content type as application/json
builder.setContentType(“application/json; charset=UTF-8”);

RequestSpecification requestSpec = builder.build();

//Making post request with authentication or leave blank if you don’t have credentials like: basic(“”,””)
Response response = given().authentication().preemptive().basic({username}, {password})
.spec(requestSpec).when().post(restAPIUrl);

String result = JSONResponseBody.getString({key});

//Check the Result
Assert.assertEquals(result, “{expectedValue}”);
