Event–based APIs are becoming more popular, enabling developers to craft new integrations and solutions that go beyond the original design of an API. Yet, there remains a challenge: how can teams design thoughtful event–basedAPIs that are long-lasting, evolvable, and discoverable?

This talk will dive into the design practices of event–basedAPIs, including tips for determining which protocol(s) you should select, design patterns we should apply, and anti-patterns should we avoid. We will also cover the latest details about the AsyncAPI specification, which provides a machine-readable way to discover and consume events across multiple protocols.
