Hi All,

I’m new to the API testing category.  
I’ve setup an Object Repositry for API via the following steps…

1. Right Click on Object Reposity
2. From the Option Menu \>\> Click on Import from Swagger
3. Typed in URL
4. Click OK

Currently, for every API Call I need to change the Authorization Token manually and it’s very frustrating.  
Is there a way of to pick up the token automatically or set it in a data file?

Any help will be appreciated.

Thanks in advance.

Hi [mkleyn](http://forum.katalon.com/u/mkleyn)

Instead of using the hard code value, you can extract the Token from login API and assign it to another API header.

> Hi [Julian\_Wladyczynski](http://forum.katalon.com/u/Julian_Wladyczynski) Please retry by following this step: 1. Assigned access\_token value to the GlobalVariable response = WS.sendRequest(findTestObject('Employees/Login backoffice and get access token')) WS.verifyResponseStatusCode(response, 200) JsonSlurper slurper = new JsonSlurper() Map parsedJson = slurper.parseText(response.getResponseText()) String access\_token = parsedJson.access\_token GlobalVariable.Token = access\_token 2. On the GET request, set the Variable as below.
