In Salesforce, developers can subscribe to platform events using both Flows and Apex Triggers. This allows for the execution of automated processes in response to the events. Apex Triggers can be written to respond to event messages in the same way they respond to DML events. Similarly, Flows can be configured to trigger upon the receipt of a platform event. This functionality is documented in Salesforce's developer guides and best practices, which emphasize the versatility and power of combining declarative and programmatic approaches to respond to platform events.

For investigating errors during development, Salesforce recommends using the Streaming API Subscription Channel for Commerce Diagnostics Event Logging. This tool allows developers to subscribe to a real-time feed of system events, including errors, which can be crucial for diagnosing and resolving issues during development. The Streaming API provides a robust mechanism for monitoring and debugging by delivering secure, scalable, and customizable event notifications within Salesforce or through external systems. This is outlined in Salesforce documentation related to the Streaming API and its application in commerce diagnostics and event logging.

To modify the out-of-the-box checkout flow template in Salesforce B2B Commerce, a developer should clone the existing template, make the necessary modifications, activate the modified template, and then reference it in the Experience Builder. This approach ensures that the original template remains intact and provides a fallback option. Salesforce documentation on customizing the checkout flow in B2B Commerce emphasizes the importance of using the Experience Builder for such customizations, providing a visual interface to manage and reference different checkout flow templates.
