Messaging API client for Messenger

Messenger

Table of Contents

Installation

npm i --save messaging-api-messenger

or

yarn add messaging-api-messenger

Usage

Initialize

const { MessengerClient } = require('messaging-api-messenger');

const client = new MessengerClient({
  accessToken: ACCESS_TOKEN,
  appId: APP_ID,
  appSecret: APP_SECRET,
  version: '6.0',
});

If the version option is not specified, 6.0 will be used by default.

Verifying Graph API Calls with appsecret_proof

If appSecret is provided, MessengerClient will enable this feature automatically and include appsecret_proof in every Graph API requests. To skip it, set the skipAppSecretProof option to true:

const client = new MessengerClient({
  accessToken: ACCESS_TOKEN,
  appId: APP_ID,
  appSecret: APP_SECRET,
  skipAppSecretProof: true,
});

Error Handling

messaging-api-messenger uses axios as HTTP client. We use axios-error package to wrap API error instances for better formatting error messages. Directly calling console.log with 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.sendRawBody(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
});

API Reference

All methods return a Promise.

Quick Replies

To send messages with quick replies to the specified user using the Send API, pass quickReplies option to send message methods, for example, with sendText:

await client.sendText(USER_ID, 'Pick a color:', {
  quickReplies: [
    {
      contentType: 'text',
      title: 'Red',
      payload: 'DEVELOPER_DEFINED_PAYLOAD_FOR_PICKING_RED',
    },
  ],
});

with the sendImage option:

await client.sendImage(USER_ID, 'https://example.com/vr.jpg', {
  quickReplies: [
    {
      contentType: 'text',
      title: 'Red',
      payload: 'DEVELOPER_DEFINED_PAYLOAD_FOR_PICKING_RED',
    },
  ],
});

It works with all of message sending methods.

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:

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

Testing

Point Requests to Your Dummy Server

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

const { MessengerClient } = require('messaging-api-messenger');

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

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