In realtime situation of an IT services from development phases to production the all time lifesaver would be the proper "logging mechanism" in place,  to avoid stress in development lifecycle and chaos after moving our application or apis onto production.   Even I have got this situation in my project and I have implemented this common Logging requirement for one of the reputed banks a while ago, so i thought to share this, so you can tweak as per you requirements. As of now we have two major version in IBM API Connect like V5 and V2018, the major difference with these new version are gateways, so this policy can be applied on the V5 compatibility Gateways only.
