Hi Hiazam
As discussed in our support case, you need to make a POST using the rest_access method to get back the access_key
Here is the call in raw format:
POST http://server1:8050/caisd-rest/rest_access HTTP/1.1
Accept-Encoding: gzip,deflate
Content-Type: application/xml;charset=UTF-8
Authorization: Basic U2VydmljZURlc2s6Zmx5JGF3YXk=
Content-Length: 14
Host: server1:8050
Connection: Keep-Alive
User-Agent: Apache-HttpClient/4.1.1 (java 1.5)
<rest_access/>
And the response in xml format:
<rest_access id="400408" REL_ATTR="400408" COMMON_NAME="1713767291">
<link href="http://server1:8050/caisd-rest/rest_access/400408" rel="self"/>
<access_key>1713767291</access_key>
<expiration_date>1470692742</expiration_date>
</rest_access>
Here is the screenshot from SoapUI:
Hope it helps.
Regards,
Gordon.
