Passing values into API calls

Hi,

I need to be able to pass values between API calls.

For example, if I have 2 API calls, getToken and getUsers and from getToken I obtain token that I need to pass to getUsers call as a part of HTTP Header.

 

Something like “Authorization”: “Bearer ${GlobalVariable.gToken}”

 

Thanks,
R

Hopefully, going thru this sample test case you will find the answer

Hi Rasko,
first of all, you have to save your token from first API call into a variable.
Then, please try following code:

TestObjectProperty prop = new TestObjectProperty()
prop.setName("Authorization")
prop.setValue("Bearer " + yourToken)

List<TestObjectProperty> headers = new ArrayList<>()
headers.add(prop)

RequestObject reqObj = new RequestObject()
reqObj.setHttpHeaderProperties(headers)
reqObj.setRestRequestMethod('POST')
reqObj.setRestUrl('https://www.yourserver.com/api/endpoint')

def getResponse = WSBuildInKeywords.sendRequest(reqObj)

@Marek. I have used the same method that you have suggested, however the tool is thrown with the following error. Any thoughts ?
