@botpress/channel-slack
Advanced tools
Official Slack connector module for Botpress.
This module has been built to accelerate and facilitate development of Slack bots.
Installing modules on Botpress is simple.
npm i --save @botpress/channel-slack
To setup connexion of your chatbot to Slack, you need to fill the connexion settings directly in the module interface. In fact, you only need to follow these steps and your bot will be ready to use.
Settings can also be set programmatically by providing the settings in the config/channel-slack.json
You need to manually enter your hostname. If you are developping locally, we suggest using ngrok to deploy your chatbot (learn more about ngrok
These information are available on Basic Information of you app. You only need to copy them in module interface.
On the OAuth & Permissions page of your slack app, you need to enter your redirect url for the authentification. The redirect url need to be ${hostname}/modules/channel-slack as you can see in the example screenshot below.
On the Bot Users page of your slack app, you need to add a Bot User by clicking on Add a Bot User. We suggest you to turn on Always Show My Bot as Online for be able to use RTM API correctly.
On the Interactive Components page of your slack app, you need to Enable Interactive Components and add a Request URL. The URL entered needs to be format as ${hostname}/api/botpress-slack/action-endpoint.
On your configuration page of your module, you need to set scope of your bot. We suggest you to keep the default configuration (admin,bot,chat:write:bot,commands,identify,incoming-webhook,channels:read), but if you want to want to modify it, we suggest you to look to the documentation.
Next step is to authenticate and connect your bot. To do it, you only need to click on Authenticate & Connect on your module and follow the steps. Once it will be done, you should received an API Token and a Bot Token. They will appear on your settings page of your module.
If you want to have more information about documentation, options and API, we suggest you to look at the official slack documentation.
You can listen to incoming event easily with Botpress by using bp built-in hear function. You only need to listen to specific Slack event to be able to react to user's actions.
bp.hear({ platform: 'slack', type: 'message', text: 'Hello' }, (event, next) => {
bp.slack.sendText(event.channel.id, 'Welcome on Botpress!!!')
})
In fact, this module preprocesses almost all types of message (message, reaction, attachments, file, typing...) and send them to incoming middlewares. When you build a bot or a module, you can access to all information about incoming messages that have been send to middlewares.
bp.middlewares.sendIncoming({
platform: 'slack',
type: 'message',
text: 'Text message here... (e.g. Hello world)'
user: [Object],
channel: { id: 'D45FHSDEW' },
ts: '1487273756.000116',
direct: true,
raw: [Object]
})
You can acces to all user's profile information (event.user) by using this module. A cache have been implemented to fetch all information about users and this information is sent to middlewares.
{
"id": "U023BECGF",
"team_id": "T021F9ZE2",
"name": "bobby",
"deleted": false,
"status": null,
"color": "9f69e7",
"real_name": "Bobby Tables",
"tz": "America\/Los_Angeles",
"tz_label": "Pacific Daylight Time",
"tz_offset": -25200,
"profile": {
"avatar_hash": "ge3b51ca72de",
"first_name": "Bobby",
"last_name": "Tables",
"real_name": "Bobby Tables",
"email": "bobby@slack.com",
"skype": "my-skype-name",
"phone": "+1 (123) 456 7890",
"image_24": "https:\/\/...",
"image_32": "https:\/\/...",
"image_48": "https:\/\/...",
"image_72": "https:\/\/...",
"image_192": "https:\/\/..."
},
"is_admin": true,
"is_owner": true,
"has_2fa": false
}
Note: All new users are automatically saved by this module in Botpress built-in database (bp.db).
An event is sent to middlewares for each incoming text message from Slack platform with all specific information.
{
platform: 'slack',
type: 'message',
text: 'Text message here... (e.g. Hello world)',
user: [Object],
channel: { id: 'D45FHSDEW' },
ts: '1487273756.000116',
direct: true,
raw: [Object]
}
Then, you can listen easily to this event in your module or bot
bp.hear('hello')
{
platform: 'slack',
type: 'reaction',
text: 'Dany Fortin-Simard reacted using wink',
user: [Object],
reaction: 'wink',
channel: { id: 'D45FHSDEW' },
ts: '1487273756.000116',
direct: true,
raw: [Object]
}
{
platform: 'slack',
type: 'typing',
text: 'Sylvain Perron is typing',
user: [Object],
channel: { id: 'D45FHSDEW' },
ts: '1487273756.000116',
direct: true,
raw: [Object]
}
{
platform: 'slack',
type: 'file',
text: 'Justin Watson shared a file',
user: [Object],
file: [Object],
channel: { id: 'D45FHSDEW' },
ts: '1487273756.000116',
direct: true,
raw: [Object]
}
User mentioned is sent each time a user mentions another user in a message.
{
platform: 'slack',
type: 'user_mentioned',
text: 'User has been mentioned',
user: [Object],
mentionedId: 'U41H4NB9N',
channel: { id: 'D45FHSDEW' },
ts: '1487273756.000116',
direct: true,
raw: [Object]
}
Bot mentioned is sent to incoming middlewares when your bot is mentioned in a message.
{
platform: 'slack',
type: 'bot_mentioned',
text: 'Bot has been mentioned',
user: [Object],
mentionedId: 'U41H4NB9N',
channel: { id: 'D45FHSDEW' },
ts: '1487273756.000116',
direct: true,
raw: [Object]
}
Slack connector also receives all other events that come from Real Time Messaging API. You can look at the documentation to have more information about some specific event.
{
platform: 'slack',
type: 'other_types',
text: 'An another type of event occured',
raw: [Object]
}
As you can see in all incoming events, we added a particular field direct to differentiate message that comes from channel or direct.
{
direct: false
}
This module also comes with some validation to be certain that events are coming from Slack API. For that, each incoming event are validated using your verification token.
By using our module, you can send anything you want to your users on Slack. In fact, this module support most important types of messenge that are available on Slack (text, attachments, button, reaction).
Note that all the below actions are available under two format: send___ and create____, the latter effectively only creating the middleware Event without piping (sending) it to the outgoing middleware. This is useful when combining libraries together (for example Botkit):
// This message won't be sent
const message = bp.slack.createText(event.channel.id, 'What is your name?')
// But `message` is a fully formed middleware event object, ready to be sent
// example using the botpress-botkit module
convo.ask(message, function(response, convo) { /* ... */ })
In code, it is simple to send a message text to a specific channel (slack doc).
sendText(channel, text, [options]) -> PromisechannelId (String): Correspond to unique Channel's recipient identifier. Usually, this channelId is available from input message.
text (String): Text message that will be send to channel.
options (Object): An object that may contain possible options for normal chat.postMessage (see documentation for more details)
(Promise): Send to outgoing middlewares a formatted Object than contains all information (platform, type, text, raw) about the text message that needs to be sent to Slack platform. The promise resolves when the message was successfully sent to slack.
bp.hear({ platform: 'slack', text: 'Hello'}, event => {
const channelId = event.channel.id
const text = 'Hello human!'
bp.slack.sendText(channelId, text)
.then(() => {
//Do something else
})
})
By using this function, you can send any type of attachment to your users (slack doc. Also, you should look to the message builder to have a better idea of all possible attachments you can send.
sendAttachments(channelId, attachments, [options]) -> PromisechannelId (String): Correspond to unique Channel's recipient identifier. Usually, this channelId is available from input message.
attachments (Array): An array of attachments to be sent.
options (Object): An object that may contain possible options for normal chat.postMessage (see documentation for more details)
(Promise): Send to outgoing middlewares a formatted Object than contains all information (platform, type, text, raw) about the attachment that needs to be sent to Slack platform.

bp.slack.sendReaction('kissing_smiling_eyes', { channel: event.channel.id, timestamp: event.ts })
})
