Point to Point integrations slow down business. Cost and complexity increases over time.
Build integrations which are event driven and much easy to scale.
You can publish the event from Salesforce and external systems can capture it and work on the event.
Change Data Capture : Keep external systems in sync when data changes in Salesforce.
You can use declarative connectors of MuleSoft, Dellbhoomi to subscribe to the change events. You can also write custom code using CometD library to subscribe the events.
23 standard objects and custom objects are available for change data capture.
Create a platform event and tie it to the object. In this example we tie Part Number field of platform event with Part Number field on Case object.
You can write apex trigger on platform event.
Using replayid, subscriber can read from that point.
