Updating of approval record through 3rd party inbound Integration

[TejaswiniB62848]

How can I update an approval record through a third-party integration (Postman) so that the Updated by field in the activity log reflects the approver’s name, rather than the integration account?

It is possible if you are using Scripted Rest API. You can use below script to impersonate as approver before approving:

var impUser = new GlideImpersonate();
impUser.impersonate("<sys_id of approver>");

Thanks Palani for your response.
I have used the above method like gs.getSession().impersonate(<sys_id of the approver>"); and it didn't work properly until i gave admin access to integration account

You need to grant "impersonator" role. Ensure the integration user has approval access and "impersonator" role

After granting impersonator role, still it doesn't seem to work. it only approves the specific approval record and blocks the workflow.
