Postman returns Error 400 with Qlik API .

[hesh]

I am trying to use postman to use Qlik Rest API but it always returns this error. I also added the certificates for POSTMAN but it is still not working.

Any help would be appreciated..

Hello @hesh ,

Does this work in PowerShell as a test?  Replace qlikserver1 with your instance:

$hdrs = @{}
$hdrs.Add("X-Qlik-xrfkey","12345678qwertyui")
$url = "https://qlikserver1.domain.local/qrs/about?xrfkey=12345678qwertyui"
Invoke-RestMethod -UseDefaultCredentials -Uri $url -Method Get -Headers $hdrs -SessionVariable websession
$cookies = $websession.Cookies.GetCookies($url)

Try that, and see if it returns a response outside of Postman, from the Qlik server and from the client machine.  My experience is that sometime Postman requires some additional steps.

If outside the Qlik server, you may need to export the certificates as shown here:

This should help get you going.
