Integrating Constant Contact API into a Next.js application

I'm trying to integrate the Constant Contact API into my Next.js application. I've looked through the documentation, but it only provides examples for PHP and Java. How can I effectively use the authentication flow and create an app on the dashboard to generate just one token? Any guidance on how to utilize that token?

Integrating the Constant Contact API into a Next.js application requires several steps, and although I can't cover everything in one response, I will outline the main process for you.

Register Your Application with Constant Contact:

Go to the Constant Contact Developer Portal and create a new app. Make sure to jot down the API key and client secret for future use.

Setting Up Your Next.js App:

Create a new Next.js app or utilize an existing one.

Install Axios or another HTTP client to handle API requests.

npm install axios

Authentication Process with Constant Contact:

3.1 OAuth2.0 Flow (For Access and Refresh Token):

Direct users to the Constant Contact authorization URL:

https://api.cc.email/v3/idfed?client_id=YOUR_API_KEY&redirect_uri=YOUR_REDIRECT_URI&response_type=code&scope=contact_data

Upon authorization, Constant Contact will redirect back to your specified redirect URI with a code parameter in the URL.

Exchange this code for an access token:

// pages/api/getAccessToken.js

import axios from 'axios';

export default async (req, res) => {
  const { code } = req.query;

  try {
    const response = await axios.post('https://idfed.constantcontact.com/as/token.oauth2', {
      grant_type: 'authorization_code',
      code: code,
      redirect_uri: 'YOUR_REDIRECT_URI',
      client_id: 'YOUR_CLIENT_ID',
      client_secret: 'YOUR_CLIENT_SECRET'
    });

    const { access_token, refresh_token } = response.data;

    // Securely store these tokens (e.g., session or encrypted cookie)
    res.status(200).json({ access_token, refresh_token });
  } catch (error) {
    res.status(500).json({ error: 'Failed to fetch access token' });
  }
}

3.2 Utilizing One Token (API Key Authentication): If opting for API Key authentication, you can utilize your API key for API calls. This method, however, lacks user-specific data access and functionality.

Sending Requests to Constant Contact API:

Once you acquire the access token, you can send authenticated requests:

import axios from 'axios';

const constantContactApi = axios.create({
  baseURL: 'https://api.cc.email/v3',
  headers: {
    'Authorization': `Bearer YOUR_ACCESS_TOKEN`
  }
});

constantContactApi.get('/contacts').then(response => {
  console.log(response.data);
});

Managing Token Expiration and Refreshment:

The access token expires after some time, requiring the use of the refresh token to obtain a new one:

export const refreshAccessToken = async (refresh_token) => {
  try {
    const response = await axios.post('https://idfed.constantcontact.com/as/token.oauth2', {
      grant_type: 'refresh_token',
      refresh_token: refresh_token,
      client_id: 'YOUR_CLIENT_ID',
      client_secret: 'YOUR_CLIENT_SECRET'
    });

    return response.data;
  } catch (error) {
    throw new Error('Failed to refresh token');
  }
}

Securing and Storing Tokens:

Always securely store tokens, like using sessions or encrypted cookies in Next.js. Avoid exposing your client secret or tokens in client-side scripts. Implement effective error handling for managing failed requests and token expirations.
