How to pass client certificate to company's internal REST api from ServiceNow

[neha_joshi]

I am creating an outbound REST message and I need to call our company's internal REST api via layer7. How do I attach the SSL certificate in the GET REST api call?

Hi Neha,

If I understand your question correctly this link may be what you're looking for: Outbound SOAP Web Service - ServiceNow Wiki

More specifically starting at section 5.2

Hi Chris, Thank you for your reply. The link (section 5.2) that you shared refers to SOAP messages. I am trying to call REST API. For this, I did the configuration as follows.

1) Create a certificate of type PKCS12 keystore with the valid certificate attachment. Lets call it "myKeystore".

2) Create protocol profile "myhttps" using the above keystore myKeystore

3) Create a new REST message call "myRESTAPICall". The endpoint is "myhttps://<endPointURL>"

4) Configure it to use "myhttps" protocol

On testing GET api call, I get response code as 500, and do not see any other response message. I am able to call the same REST API with the valid certificate via other tools like SOAP UI/Fiddler.

I apologize but I meant 5.3 for mutual authentication. It's basically the same steps of creating a protocol profile and certificate keystore so that when configuring the REST message to use mutual authentication it can be used.
