Slack Web API

The simplest library for Slack Web API.

Call Slack Web API endpoints just like functions

Installation

Install via npm

npm install slack-wrapi --save

Usage

Create a Slack client with the API token.

const slackWrapi = require('slack-wrapi');

const slack = new slackWrapi(SLACK_API_TOKEN);

// Now you are ready to make API calls to Slack.

Function names match with Slack API endpoints (methods) as per the documentation.

Just provide parameters and a callback or get back a Promise.

API calls follow this syntax:

slack.apigroup.action(queryString, callback);

queryString - (as required) API method parameters as key-value pairs.

If no callback is provided, the function returns a Promise object.

Post a message with callback:

// ES5 Syntax with callback
slack.chat.postMessage({
    "channel": "#general",
    "text": "Hello World!"
  },
  function(err, res) {
    if (!err) {
      console.log('Message posted: ', res.ts);  
    }
  }
)

Post a message. Get back a Promise:

// ES2015 Promise
slack.chat.postMessage({
  "channel": "#general",
  "text": "Hello World!"
})
.then((res) => {
  console.log('Message posted: ', res.ts);  
})
.catch(console.error);

Post a message via async/await:

// ES2017 async/await
(async () => {
  try {
    const res = await slack.chat.postMessage({
      "channel": "#general",
      "text": "Hello World!"
    });

    console.log('Message posted: ', res.ts);  
  }
  catch(err) {
    console.error(err);
  }
})();

Call any Slack Web API methods with the client object.

Examples

Lists custom emojis for a team.

slack.emoji.list(function(err, data) {
  if (!err) {
    console.log(data);
  }
});

Lists all channels in a Slack team.

slack.channels.list({exclude_archived:1}, function(err, data) {
  if (!err) {
    console.log(data);
  }
});

Gets information about a private group.

slack.groups.info({channel:"G1234567890"}, function(err, data) {
  if (!err) {
    console.log(data);
  }
});

Adds a reaction to an item.

slack.reactions.add({
    name: "thumbsup",
    file: "F1234567890",
    file_comment: "Fc1234567890",
    channel:"G1234567890",
    timestamp: "1234567890.123456"
  },
  function(err, data) {
    if (!err) {
      console.log(data);
    }
  }
);

Gets information about a user.

slack.users.info({user: "U1234567890"}, function(err, data) {
  if (!err) {
    console.log(data);
  }
});

Post chat messages to Slack.

slack.chat.postMessage({
    "channel": "#general",
    "text": "Hello <@u12345678|world>!",
    "username": "Wrapi Bot",
    "as_user": false,
    "parse": "full",
    "link_names": 1,
    "attachments": [{"pretext": "pre-hello", "text": "text-world"}],
    "unfurl_links": true,
    "unfurl_media": false
  },
  function(err, data) {
    if (!err) {
      console.log(data);
    }
  }
)

Check user's current `Do Not Disturb` settings.

slack.dnd.info({
    "user": "U1234"
  },
  function(err, data) {
    if (!err) {
      console.log(data);
    }
