Bitrix24 Client Library

Installation

npm install b24 --save

Modes

There are 2 modes to use this library. API mode and Webhook mode.

You can specify the mode when initializing Bitrix24.

When you use API mode, you must authenticate the user using OAuth. See Authentication for example.
You also must provide client_id, client_secret, and redirect_uri in config block.

#### Method Hook
There are 2 method that will called when using API mode. saveToken(data) and retriveToken. You can use this to save and get token from database.

#### Example
``JavaScript
const b24 = require('b24');

const bitrix24 = new b24.Bitrix24({
config: {
mode: "api",
host: "your bitrix host",
client_id : "your client id",
client_secret : "your client secret",
redirect_uri : "http://localhost:3000/callback"
},
methods: {
async saveToken(data){
//Save token to database
},
async retriveToken(){
//Retrive token from database
return {
access_token: "youraccesstoken",
refresh_token: "yourrefreshtoken"
}
}
}
})
`

It use webhook feature from Bitrix24
To use this you must provide user_id and code in config block.

user_id can be obtained throught my profile page. See the URL, e.g https://k2d2.bitrix24.com/company/personal/user/4/. The value would be 4

code can be obtained throught Application -> Web hooks -> ADD WEB HOOK -> Inbound web hook

#### Example
`JavaScript
const b24 = require('b24');

const bitrix24 = new b24.Bitrix24({
config: {
mode: "webhook",
host: "your bitrix host",
user_id: "1",
code: "your_webhook_code"
}
})
`




Authentication

You must do authentication when use API mode. It just OAuth2

Step:
1. Visit url provided by bitrix24.auth.authorization_uri
2. It will give you the code in callback url, use this to get token
3. Get token with bitrix24.auth.getToken(code)
4. Profit!!!

Example:
`JavaScript
const express = require('express');
const b24 = require('b24');

const app = express()

const bitrix24 = new b24.Bitrix24({
config: {
mode: "api",
host: "your bitrix host",
client_id : "your client id",
client_secret : "your client secret",
redirect_uri : "http://localhost:3000/callback"
},
methods: {
async saveToken(data){
//Save token to database
},
async retriveToken(){
//Retrive token from database
return {
access_token: "youraccesstoken",
refresh_token: "yourrefreshtoken"
}
}
}
})

// Bitrix auth
app.get('/auth', (req, res) => {
res.redirect(bitrix24.auth.authorization_uri);
});

// Callback service parsing the authorization token and asking for the access token
app.get('/callback', async (req, res) => {
try{
const code = req.query.code;
const result = await bitrix24.auth.getToken(code);
return res.json(result);
}catch(err){
console.log(err)
return res.status(500).json({message:"Authentication Failed"});
}
});

app.listen(3000, () => {
console.log('Server started on port 3000');
});
`

Run Bitrix24 API

For complete API refrence visit https://training.bitrix24.com/rest_help/index.php

To Run Bitrix24 API we need to use callMethod(method, param) method.

pass the method you want to run in method parameter, param parameter is optional, it used to add parameter to method that you call, visit the official API reference to see all possible parameter.

Example:
`JavaScript
const express = require('express');
const b24 = require('b24');

const app = express()

const bitrix24 = new b24.Bitrix24({
config: {
mode: "webhook",
host: "your bitrix host",
user_id: "1",
code: "your_webhook_code"
}
})

// Get all Bitrix24 User
app.get('/allUser', async (req, res) => {
try{
const result = await bitrix24.callMethod('user.get');
return res.json(result);
}catch(err){
console.log(err)
return res.status(500).json({message:"Internal Server Error"});
}
})

app.listen(3000, () => {
console.log('Server started on port 3000');
});
