Generate token with NodeJS

In this article, we will explain how you can generate a Sonetel access token with NodeJS and how you can use it to interact with our API.

To get started, ensure that you have a free Sonetel account. You will have to use your username and password to acquire an access token.

The following code can be used to generate an OAuth access token for a Sonetel account, using the Sonetel API.

import http from 'https';
import FormData from 'form-data';

export const createAccessToken = (username, password) => {
    return new Promise(resolve => {
        const host = 'api.sonetel.com';
        const authUri = '/SonetelAuth/beta/oauth/token';
    
        if (!username){
            throw Error('Username is reqired to generate access token.');
        }
        if (!password){
            throw Error('Password is reqired to generate access token.');
        }
    
        const requestBody = new FormData();
        requestBody.append('grant_type', 'password');
        requestBody.append('username', username);
        requestBody.append('password', password);
        requestBody.append('refresh', 'yes');
    
        const options = {
            hostname: host,
            path: authUri,
            auth: 'sonetel-api:sonetel-api',
            method: 'post',
            headers: requestBody.getHeaders()
        }
        const req = http.request(options, (res) => {
            const { statusCode } = res;
            if(statusCode >= 500){
            throw Error (`Request failed with server error. Status code ${statusCode}`)
            }
    
            res.setEncoding('utf-8');
    
            let rawData = '';
            res.on('data', (chunk) => rawData += chunk);
            res.on('end', async () => {
            
            try {
    
                let dataToReturn;
                if (res.headers['content-type'].match(/application\/json/i)) {
                dataToReturn = JSON.parse(rawData);
                } else {
                dataToReturn = rawData;
                }
    
                resolve(dataToReturn);
    
            } catch (e) {
                console.error(e.message);
            }
    
            });
        });
        
        req.on('error', (e) => {
            throw Error(`Request failed. ${e.message}`);
        });
    
        requestBody.pipe(req);
    });
    }

The function first checks that the username and password arguments are provided. It then constructs an HTTP request to the Sonetel API, using the POST method, the grant_type, username, and password parameters, and basic authentication with the sonetel-api username and password. The request is sent and the response is handled asynchronously, extracting the access token and resolving it as a Promise.
