Package Exports
- messaging-api-slack
- messaging-api-slack/dist/SlackTypes
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (messaging-api-slack) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

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.
