Invalid authorization - Code 3 - Why Splunk Zendesk Integration failing?

[greekleo89]

Hi All,

I've stumbled on a very frustrating problem.  I've created a HEC token to use in Zendesk so that Zendesk can send webhooks to splunk.  When i try to test the connection i receive the following error:

{"text":"Invalid authorization","code":3}

I looked on the forum and found this:  https://community.splunk.com/t5/Getting-Data-In/HTTP-Event-Collector-Why-am-I-getting-error-quot-Inv... 

I have tried to put the user  Splunk in front of the token and can see in chrome developer tools that it is being sent, however i am not able to successfully connect.

From another machine on the network, with curl and using the word Splunk i am able to successfully post a message.

Please note I do not believe this to be a firewall/port issue as that problem was resolved for me to get to this stage.

Any help would be appreciated.

Thanks in advance
