Amazon Connect now supports custom flow block titles that make it easy to identify and distinguish blocks within your flow. Custom flow block titles can be set within the flow designer UI or via API. For example, you could rename a “Play Prompt” flow block to “Welcome message” or a “Get customer input” flow block to “Hotel booking Lex bot”. Custom defined flow block titles also show up in CloudWatch logs making it easier to diagnose where errors may be occurring.
