Send Events to Salesforce using API Destinations
After processing the events in AWS, you can publish an event to Salesforce using an API destination. An API destination is an HTTP endpoint that an EventBridge rule can invoke.
To publish an event to Salesforce, the API destination configuration contains the REST API endpoint of the platform event and performs a POST request to this endpoint. It uses the Salesforce org authentication credentials that you set. The sent event must be defined as a custom platform event in Salesforce. Subscribers that have been set up for this platform event, such as a flow or an Apex trigger, receive the sent platform event and can process it.
