Table of Contents

Installation

OAuth Client

Usage

Get your bot user OAuth access token by setup OAuth & Permissions function to your app or check the Using OAuth 2.0 document.

const { SlackOAuthClient } = require('messaging-api-slack');

// get access token by setup OAuth & Permissions function to your app.
// https://api.slack.com/docs/oauth
const client = new SlackOAuthClient({
  accessToken: 'xoxb-000000000000-xxxxxxxxxxxxxxxxxxxxxxxx',
});

Error Handling

messaging-api-slack uses axios as HTTP client. We use axios-error package to wrap API error instances for better formatting error messages. Directly console.log on the error instance will return formatted message. If you'd like to get the axios request, response, or config, you can still get them via those keys on the error instance.

client.callMethod(method, body).catch((error) => {
  console.log(error); // formatted error message
  console.log(error.stack); // error stack trace
  console.log(error.config); // axios request config
  console.log(error.request); // HTTP request
  console.log(error.response); // HTTP response
});

Debug Tips

Log Requests Details

To enable default request debugger, use following DEBUG env variable:

DEBUG=messaging-api:request

If you want to use a custom request logging function, just provide your own onRequest:

// for SlackOAuthClient
const client = new SlackOAuthClient({
  accessToken: ACCESS_TOKEN,
  onRequest: ({ method, url, headers, body }) => {
    /* */
  },
});

// for SlackWebhookClient
const client = new SlackWebhookClient({
  url: URL,
  onRequest: ({ method, url, headers, body }) => {
    /* */
  },
});

Testing

Point Requests to Your Dummy Server

To avoid sending requests to real Slack server, specify the origin option when constructing your client:

const { SlackOAuthClient } = require('messaging-api-slack');

const client = new SlackOAuthClient({
  accessToken: ACCESS_TOKEN,
  origin: 'https://mydummytestserver.com',
});

Warning: Don't do this on your production server.
