How come our Splunk 6.5 REST API calls with curl command are not working?

[mukesh2019]

Hi,

I have the following REST call on a new 6.5 environment, and it's coming back with error

curl -X POST -u user:pass -k http://host.domain.com:8000/en-US/splunkd/services/search/jobs -d search="search *"

I'm able to get the session key with same credentials :-

curl -k http://host.domain.com:8000/en-US/splunkd/services/auth/login --data-urlencode username=user--data-urlencode password=pass

<response>
 <sessionKey>yATMHjpws9MOIGi5Rg9QvsoRR4EMncSGxlerJ9W6B....</sessionKey>
</response>

Please suggest. Apologies for the editing, I'm new at this.

Thanks

Hello @mukesh2019,

You are using the wrong port.

Splunk's management port is 8089. You also need to use https instead of http.

Also remove the language modifier. It should look like this:

https://host.domain.com:8089/services/search/jobs

Check out the REST API documentation.

Thanks a lot 🙂
