Bi-directional Incident Integration Between Two ServiceNow Instances Using OAuth

[Mahalakshmi Rav]

Hi all,

I have a requirement where I need to showcase bi-directional integration between two ServiceNow instances (let’s call them PDI A and PDI B) for the Incident table.

Whenever an incident is created, updated or deleted in one instance, it should automatically reflect in the other instance PDI A to PDI B, and vice versa so changes in PDI B should also sync back to PDI A.

I want to use OAuth 2.0 for authentication instead of basic auth and that's the main requirement here.

Steps which i executed:
1. So far, I have created an OAuth profile in Instance B (as an OAuth client) and created one integration user with the necessary roles and web service access is enabled.

2. In Instance A, I created an OAuth provider profile using the same client ID and secret, set up a REST message and successfully generated an OAuth token. I then created a POST method, but when I try to test 'Create INC http', it’s throwing an error.

I’m not sure what went wrong, can someone please advise?

Thanks!

Hello @adilalee200 , You only need to provide the rest_service and itil user roles and you can remove the rest. For the POST HTTP request, make sure that the authentication option is set to "Inherit from Parent."

I haven't achieved mine using the Scheduled Job and Script Include. May I know what error you are facing?
