Integrating Stripe Metered Billing into the OpenClaw SaaS Boilerplate

How to Add Stripe Metered Billing to the OpenClaw SaaS Boilerplate

Answer: Integrating Stripe metered billing into the OpenClaw customer portal involves creating a metered product in Stripe, configuring API keys in OpenClaw, tracking usage on the backend (Node.js), displaying usage and invoices on the React frontend, testing end‑to‑end, and finally deploying the updated app on UBOS hosting.

1. Introduction

OpenClaw is a modern SaaS boilerplate that ships with authentication, a customer portal, and a flexible plugin system. When you need to charge customers based on actual consumption—such as API calls, storage usage, or seat‑based licensing—Stripe’s metered billing is the industry‑standard solution.

This guide walks developers through every step: from Stripe product creation to code implementation, testing, and deployment on UBOS. By the end, you’ll have a production‑ready metered‑billing flow that scales securely.

2. Prerequisites

• Running OpenClaw (Node.js ≥ 18, React ≥ 18) on your local machine.
• A Stripe account with metered‑usage documentation access.
• Node.js package manager (npm or yarn) and Git.
• Basic knowledge of REST APIs and React state management.

3. Creating a Stripe Metered Billing Product

Follow these steps in the Stripe Dashboard:

1. Navigate to Products → Add product.
2. Enter a name (e.g., API Calls) and description.
3. Under Pricing model, select Metered usage.
4. Set the unit amount (e.g., $0.001 per call) and the billing interval (monthly).
5. Save the product and copy the Product ID (e.g., prod_ABC123).

4. Configuring OpenClaw to Use Stripe API Keys

OpenClaw stores secrets in .env. Add the following variables:

# .env
STRIPE_SECRET_KEY=sk_test_XXXXXXXXXXXXXXXXXXXXXXXX
STRIPE_WEBHOOK_SECRET=whsec_XXXXXXXXXXXXXXXXXXXXXXXX
STRIPE_PRODUCT_ID=prod_ABC123

Restart the server so the environment variables are loaded.

5. Implementing Metered Usage Tracking in the Customer Portal

OpenClaw’s backend exposes a /api/usage endpoint. We’ll extend it to record usage events via Stripe’s UsageRecord API.

5.1 Backend (Node.js) – Adding the Endpoint

// src/routes/usage.js
const express = require('express');
const router = express.Router();
const Stripe = require('stripe');
const stripe = Stripe(process.env.STRIPE_SECRET_KEY);

/**
 * POST /api/usage
 * Body: { userId: string, quantity: number }
 */
router.post('/', async (req, res) => {
  const { userId, quantity } = req.body;
  if (!userId || !quantity) {
    return res.status(400).json({ error: 'Missing parameters' });
  }

  try {
    // 1️⃣ Retrieve the Stripe subscription for the user
    const subscription = await stripe.subscriptions.list({
      customer: userId,
      limit: 1,
    });

    if (!subscription.data.length) {
      return res.status(404).json({ error: 'Subscription not found' });
    }

    const subscriptionItemId = subscription.data[0].items.data[0].id;

    // 2️⃣ Create a usage record
    const usageRecord = await stripe.subscriptionItems.createUsageRecord(
      subscriptionItemId,
      {
        quantity,
        timestamp: Math.floor(Date.now() / 1000),
        action: 'increment',
      }
    );

    res.json({ success: true, usageRecord });
  } catch (err) {
    console.error('Stripe usage error:', err);
    res.status(500).json({ error: 'Internal server error' });
  }
});

module.exports = router;

5.2 Frontend (React) – Reporting Usage

In the customer portal, add a button that sends usage data to the new endpoint.

// src/components/UsageButton.jsx
import { useState } from 'react';
import axios from 'axios';

export default function UsageButton({ userId }) {
  const [loading, setLoading] = useState(false);
  const [msg, setMsg] = useState('');

  const reportUsage = async (qty) => {
    setLoading(true);
    try {
      const res = await axios.post('/api/usage', {
        userId,
        quantity: qty,
      });
      setMsg(`✅ Recorded ${qty} units`);
    } catch (e) {
      setMsg('❌ Failed to record usage');
    } finally {
      setLoading(false);
    }
  };

  return (
    

       reportUsage(1)}
        disabled={loading}
      >
        {loading ? 'Reporting…' : 'Report 1 Unit'}
      
      {msg && 
{msg}
}
    
  );
}

5.3 Displaying Current Usage & Invoices

OpenClaw already ships a Billing page. Extend it to fetch usage summary:

// src/pages/Billing.jsx
import { useEffect, useState } from 'react';
import axios from 'axios';

export default function Billing() {
  const [usage, setUsage] = useState(null);
  const [invoice, setInvoice] = useState(null);

  useEffect(() => {
    async function fetchData() {
      const [uRes, iRes] = await Promise.all([
        axios.get('/api/stripe/usage'),   // custom endpoint you’ll add
        axios.get('/api/stripe/invoice'), // existing endpoint
      ]);
      setUsage(uRes.data);
      setInvoice(iRes.data);
    }
    fetchData();
  }, []);

  return (
    

      
Current Month Usage
      {usage ? (
        
{usage.total_quantity} units used – ${usage.amount_due / 100} billed
      ) : (
        
Loading usage…
      )}

      
Latest Invoice
      {invoice ? (
        
          View Invoice #{invoice.number}
        
      ) : (
        
Loading invoice…
      )}
    
  );
}

6. Testing the Integration

Before pushing to production, verify each piece works end‑to‑end.

1. Unit tests: Use jest to mock Stripe calls and assert that createUsageRecord receives the correct quantity.
2. Local sandbox: Stripe provides a test mode. Create a test customer, subscribe to the metered product, and call the /api/usage endpoint with various quantities.
3. Dashboard verification: In the Stripe Dashboard, navigate to the test subscription → Usage records to see the recorded events.
4. Frontend sanity check: Click the “Report 1 Unit” button and confirm the success message and updated usage display.

7. Best‑Practice Tips

7.1 Security

• Never expose STRIPE_SECRET_KEY to the browser. Keep all Stripe calls server‑side.
• Validate userId against your own authentication system before creating a usage record.
• Rotate webhook secrets regularly and store them in a secret manager (e.g., AWS Secrets Manager).

7.2 Error Handling

• Implement exponential back‑off for transient Stripe API errors (HTTP 429, 5xx).
• Log failed usage events to a dead‑letter queue for later reconciliation.
• Return clear error messages to the UI so users understand if a usage report failed.

7.3 Scaling Considerations

• Batch usage records when possible (e.g., aggregate per minute) to stay under Stripe’s rate limits.
• Use a message broker (RabbitMQ, Kafka) to decouple usage collection from Stripe API calls.
• Cache subscription‑item IDs in Redis to avoid repeated look‑ups.

8. Deploying with UBOS Hosting

Once your code passes local tests, push it to your Git repository and let UBOS handle the rest. UBOS provides a one‑click OpenClaw hosting experience that includes automatic SSL, CI/CD pipelines, and horizontal scaling.

Follow these steps:

1. Connect your GitHub repo to the UBOS dashboard.
2. Select the UBOS templates for quick start that match the OpenClaw stack (Node.js + React).
3. Configure environment variables (STRIPE_SECRET_KEY, STRIPE_WEBHOOK_SECRET, STRIPE_PRODUCT_ID) in the UBOS UI.
4. Enable the Workflow automation studio to trigger a webhook deployment whenever you merge to main.
5. Review the UBOS pricing plans to ensure you have enough compute for expected traffic.
6. Deploy! UBOS will provision containers, set up a PostgreSQL instance, and expose your app at a secure https:// URL.

After deployment, verify that the webhook endpoint (/api/stripe/webhook) is reachable from Stripe’s dashboard. Use the “Send test webhook” button to confirm that usage events are processed correctly in production.
