API Get sys_id using a Change Number

[Ninh V Bui]

Hi all, 

Objective: Use API to get sys_id using a Change Number

I'm new to scripting and I am using POSTMAN to use ServiceNow API to request for response in order to pass data on to other APIs for other apps. 

I know that you can GET a response from a Change record if you have its sys_id but can we do the opposite? Is there a way to search up using the CHG number and have it respond back the sys_id record?

What I'm looking for is when we get a Change number coming through an email. We copy that Change number into the script and it goes and open up that sys_id record. Instead of us having to go through the CHG record > Right click and copy sys_id

Any help would be much appreciated. 

Thank you

In post man you can do a get

https://####.service-now.com/api/now/table/change_request?sysparm_query=number%3DCHG0001090

Gets the sys_id

            "follow_up": "",
            "sys_id": "76732a25d7223100b96d45a3ce6103e5",
            "contact_type": "phone",
