Setting Up Next.js Authentication with Eartho

Step 1: Install the Eartho SDK

Start by installing the Eartho SDK:

npm install @eartho/one-client-react

Step 2: Initialize Eartho in Your Application

Next, wrap your Next.js application in the Eartho provider. You’ll need to obtain your Eartho client ID from the Eartho Creator Dashboard.

// src/pages/_app.js
import React from 'react';
import { EarthoOneProvider } from '@eartho/one-client-react';
import '../styles/globals.css';

function MyApp({ Component, pageProps }) {
return (
<EarthoOneProvider clientId="YOUR_EARTHO_CLIENT_ID">
<Component {...pageProps} />
export default MyApp;

Step 3: Implement Authentication in Your Components

Utilize Eartho’s hooks to manage the authentication state in your components:

// src/pages/index.js
import React from 'react';
import { useEarthoOne } from '@eartho/one-client-react';
const HomePage = () => {
const {
} = useEarthoOne();
if (isLoading) return <div>Loading...</div>;
if (isConnected) {
return (
Hello, {user.displayName}
<button onClick={() => logout({ returnTo: window.location.origin })}>Logout</button>
return (
<button onClick={() => connectWithPopup({ accessId: "YOUR_EARTHO_ACCESS_ID" })}>
Log In
export default HomePage;Integrating Payments with Eartho

Eartho simplifies the process of integrating payments into your Next.js app without the need for additional SDKs. Here’s how to get started:

Step 1: Set Up Your Eartho Payment Integration

In the Eartho dashboard, go to the Finance tab and connect your payment account (such as Stripe). Fill out the necessary information, including bank details, company info, etc.

Step 2: Creating Access Points with Payments

Access points can serve as gateways for your users, providing login functionalities, subscription options, or premium upgrades. Follow these steps to create an access point with payments:

  1. Log into your Eartho Creators account.
  2. Select your project.
  3. Navigate to the “Add Access Point” section on the project page.
  4. Choose the type of access point — Login, Subscription, or Premium Upgrade.
  5. Configure the payment details and pricing model.

Step 3: Implementing Payments in Your Next.js App

Once your payment account and access points are set up, retrieve the access ID from the dashboard and use it within your code:

import React from 'react';
import { useEarthoOne } from '@eartho/one-client-react';

const PaymentComponent = () => {
const { user, connectWithPopup } = useEarthoOne();
const handleUpgrade = () => {
connectWithPopup({ accessId: "YOUR_EARTHO_PREMIUM_ACCESS_ID" })
.then(() => {
// Check user access after the upgrade
if (user.access.includes("YOUR_EARTHO_PREMIUM_ACCESS_ID")) {
console.log("User has premium access");
} else {
console.log("Upgrade failed");
.catch(error => {
console.error("Error upgrading access", error);
return (
{user.access.includes("YOUR_EARTHO_PREMIUM_ACCESS_ID") ? (
<p>You have premium access!</p>
) : (
<button onClick={handleUpgrade}>Upgrade to Premium</button>
export default PaymentComponent;
