How to Call Auth0 API After Login in Next.js

When developing applications with Next.js, implementing user authentication is a common necessity. One popular solution for authentication is Auth0. However, once you have successfully integrated Auth0 into your Next.js app, you might wonder: How do I call my protected API routes after user login? In this guide, we'll break down the steps required to achieve just that, leading you from logging in to making secure API calls.

Understanding the Scenario

In your Next.js application, you have already set up Auth0 authentication using the provided code from their documentation. Here's a recap of what you have done so far:

You've protected your index page using Auth0's login functionality.

You've implemented a separate Node.js server that serves your API and requires a valid JWT for accessing certain routes.

Now, you want to call the /api/protected endpoint that you created in your Node.js server from your React component after a user logs in successfully. Let’s walk through the process together.

Step 1: Setting Up Your API Call

To make API calls from your Next.js application, you can use libraries like Axios or the native Fetch API. In this example, we will use Axios for its simplicity.

Install Axios

First, ensure that you have Axios available in your project. If you haven't installed it yet, run the following command in your project directory:

Create the API Call Function

You will define a new function within your component to handle the API call to your protected route. Here's an example of how to set that up:

Key Points

Authorization Header: Since /api/protected is a secured endpoint, you will need to include the JWT in the Authorization header. Make sure to replace yourToken with the actual token obtained during the login process.

Step 2: Hooking Up the Function in Your Component

Now that you have your API call function, you need to ensure it is invoked at the right time within your Next.js component. You can trigger this function after verifying that the user is logged in.

Here's an example of how you can implement this in your index.js file:

Explanation

useEffect Hook: This hook will run your API call every time the user object is updated. If the user is logged in, it will trigger the function to call your protected API.

Logging the Data: You can log or otherwise handle the data received from the API as needed.

Conclusion

By following the steps outlined above, you can successfully call protected API routes after logging in with Auth0 in your Next.js application. This approach allows you to manage user authentication seamlessly while interacting with your backend services securely.
