Is there any port number which needs to be enabled in order to consume the web-services/WSDL by a vendor company ?

HI,

We are doing the integration of event monitoring tool(CA-SOI) with Service-Now and need to know that is there any specific port number which needs to be enabled at our end in order for them to consume the webservices/ WSDL.

Web services in Service-Now can be consumed using either HTTP (default port 80) or HTTPS (default port 443).

There my be other factors which are restricting access however, I have a question:

Is your Service-Now instance open to the internet (anyone can access), or only to a specific set of IPs through the IP access control ACLs in Service-Now?

If you are restricting access using these IP Access controls, you need to either:
a) add the vendors integration IP address as an allowed IP in Service-Now
b) allow the vendor to route through your existing link (VPN or whatever)

Also if you are using a proxy (squid, ironport etc) between you and Service-Now you will either have to forward 80/443 straight on to Service-Now, or include authentication headers in the HTTP(S) request to authenticate with the proxy first.

I suggest writing a quick script in Python, NodeJS, Java or something to send an HTTP(S) request off and read the response headers to try to determine what's getting in the way.

Hope this helps,
