Slack API in Go
Slack API in Go - community-maintained fork
...This library supports most if not all of the api.slack.com REST calls, as well as the Real-Time Messaging protocol over websocket, in a fully managed way. There is currently no major version released. Therefore, minor version releases may include backward incompatible changes. When using socket mode, dealing with an event can be pretty lengthy as it requires you to route the event to the right place. Instead, you can use SocketmodeHandler much like you use an HTTP handler to register which event you would like to listen to and what callback function will process that event when it occurs. -

AsyncAPI
Allows you to create machine-readable definitions of asynchronous APIs
AsyncAPI is an open-source initiative that seeks to improve the current state of Event-Driven Architecture (EDA). Our long-term goal is to make working with EDAs as easy as working with REST APIs. That goes from documentation to code generation, from discovery to event management, and beyond. The AsyncAPI Specification defines a standard, protocol-agnostic interface that describes message-based or event-driven APIs.
