This is the original Slack library for Go created by Norberto Lopes, transferred to a GitHub organization.

You can also chat with us on the #slack-go, #slack-go-ja Slack channel on the Gophers Slack.

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.

See CHANGELOG.md or Releases for more information about the changes.

As mentioned in https://api.slack.com/rtm - for most applications, Socket Mode is a better way to communicate with Slack.

See https://github.com/slack-go/slack/blob/master/examples/websocket/websocket.go

See https://github.com/slack-go/slack/blob/master/examples/eventsapi/events.go

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.

See ./examples/socketmode_handler/socketmode_handler.go
