Need to generate hmac-sha1 signature to send it part of REST request header. Any help??
Hi Team,
We are trying to analyse soapUI as an automation tool to automate our RESTful API regression tests. But while doing a prototype we are faing an issue in setting up the headers for REST requests. As we use hmac-sha1 encrytped signature [generated using a epoch timestamp, username and secret]. We didn't find any resource online which does the same, Could you please throw some light there?
Any response is highly appreciated.
Thanks!
Hi Rao,
I couldn't find a solution from those discussions. But I got it resolved using some groovy scripts.
Pasting it down here, if somebody feels helpful.

//Set the headers for that the teststep testRunner.testCase.getTestStepByName("Step1").testRequest.setRequestHeaders(headers)*****************************
