Slack Events API
5
The Events API is a streamlined, easy way to build apps and bots
that respond to activities in Slack. All you need is a Slack app and a
secure place for us to send your events.
● Subscribe the events you need and ignore the ones you don’t need.
● Events sent to you are directly tied to OAuth permissions as part of
slack app you have installed.
● Slack Apps using bots can subscribe to events related to the
channels or direct message conversations.
● Slack events can be used by 2 ways. Using POST http endpoint or
via socket mode which uses dynamic web sockets.
● In order to use slack events, appropriate permissions need to be
given to the slack app and its bot user.

The Event Loop
6
Many apps built using the Events API will follow same abstract event
driven sequence:-
1. A user creates a circumstance that triggers an event subscription to
your app
2. The server receives a JSON payload describing the event.
3. Your server acknowledges receipt of the event
4. Your business logic decides what to do about that event
5. Your server carries out that decision
6. Members send messages to channel the bot belongs to. The message
might contain certain keywords which would enable server to
perform certain actions such as posting message to channel.

Slack Authentication and Authorization
7
Slack will generate a bot token for authentication purposes. On a new
application creation it generates a slack app token having respective
permissions to perform certain operations.
● Permissions such as messages:read, messages:write, files:read,
files:write, channel:read etc have to be configured on the app for it
to allow to perform the respective operations.
● The app token and bot token will be configured on the server side
to authenticate and authorize the events coming.
● Slack continuous to ping the server in order to make sure of the
connection

Slack Integration with Anypoint Platform
● We will be using slash commands to trigger slack events.
● Slash commands acts as shortcut for specific actions
● For diff commands we will be interacting with anypoint platform
apis to perform different functions.
● We will be using Golang service as an event handler for slack
commands
● Slash commands are categorized in 3 types :-
○ Build In Slash commands :- They are default commands provided by slack.
Example /archive, /call
○ App Slash Commands :- They are created by developers for app. Example
Zoom has /zoom command and may more
○ Customised Slash commands :- These are commands that are for any new
app created in slack to perform specific tasks.
