9.24API-led vs point-to-point

Point-to-point:

System A → System B
System A → System C
System D → System B
System D → System C

As systems grow:

number of integrations explodes

API-led tries to turn:

N × M integrations

into reusable interfaces.

Example:

        Process A
        Process B
        Process C
            │
            ↓
   Salesforce System API
            ↓
       Salesforce

Much easier to govern.
