Revenue Sharing: Connect supports revenue sharing models, enabling platforms to monetize agentic commerce transactions.

Compliance: Connect handles compliance requirements for multi-party transactions.

Connect Account Setup

1. Create Connect Application: Set up a Stripe Connect application in your Stripe dashboard.

2. Configure OAuth: Implement OAuth flow for merchant account connections.

3. Set Up Webhooks: Configure webhooks for real-time transaction updates.

4. Implement Security: Implement security measures for Connect transactions.

Connect Implementation:

// Stripe Connect setup for agentic commerce
const stripe = require('stripe')(process.env.STRIPE_SECRET_KEY);

// Create Connect account for merchant
const createConnectAccount = async (merchantInfo) => {
  try {
    const account = await stripe.accounts.create({
      type: 'express',
      country: merchantInfo.country,
      email: merchantInfo.email,
      capabilities: {
        card_payments: { requested: true },
        transfers: { requested: true }
      },
      business_type: 'individual',
      individual: {
        first_name: merchantInfo.firstName,
        last_name: merchantInfo.lastName,
        email: merchantInfo.email
      }
    });
    
    return account;
  } catch (error) {
    console.error('Connect account creation error:', error);
    throw error;
  }
};

// Create Connect link for onboarding
const createConnectLink = async (accountId) => {
  try {
    const link = await stripe.accountLinks.create({
      account: accountId,
      refresh_url: 'https://your-app.com/reauth',
      return_url: 'https://your-app.com/return',
      type: 'account_onboarding'
    });
    
    return link;
  } catch (error) {
    console.error('Connect link creation error:', error);
    throw error;
  }
};

Connect OAuth Implementation

OAuth Flow Setup:

// OAuth flow for merchant connections
const handleConnectOAuth = async (req, res) => {
  try {
    const { code, state } = req.query;
    
    // Exchange code for access token
    const response = await stripe.oauth.token({
      grant_type: 'authorization_code',
      code: code
    });
    
    // Store access token for merchant
    await storeMerchantToken(response.stripe_user_id, response.access_token);
    
    // Redirect to success page
    res.redirect('/connect/success');
  } catch (error) {
    console.error('OAuth error:', error);
    res.redirect('/connect/error');
  }
};

// Generate OAuth URL
const generateOAuthURL = (merchantId) => {
  const params = new URLSearchParams({
    client_id: process.env.STRIPE_CLIENT_ID,
    redirect_uri: 'https://your-app.com/connect/callback',
    response_type: 'code',
    scope: 'read_write',
    state: merchantId
  });
  
  return `https://connect.stripe.com/oauth/authorize?${params}`;
};

Implementing Delegated Payments

Delegated payments are crucial for agentic commerce, allowing AI agents to make purchases on behalf of users with proper authorization.

Delegated Payment Overview

Authorization Model: Users authorize AI agents to make purchases within specified limits and timeframes.

Security Measures: Multiple layers of security ensure that delegated payments are secure and authorized.

Fraud Prevention: Advanced fraud detection specifically designed for AI agent transactions.

Compliance: Delegated payments comply with relevant regulations and standards.

Payment Intent Creation

Create Payment Intent:

// Create payment intent for AI agent transaction
const createPaymentIntent = async (transactionData) => {
  try {
    const paymentIntent = await stripe.paymentIntents.create({
      amount: transactionData.amount,
      currency: transactionData.currency,
      customer: transactionData.customerId,
      payment_method: transactionData.paymentMethodId,
      confirmation_method: 'manual',
      confirm: true,
      metadata: {
        agent_id: transactionData.agentId,
        transaction_type: 'agentic_commerce',
        product_id: transactionData.productId,
        user_authorization: transactionData.authorization
      }
    });
    
    return paymentIntent;
  } catch (error) {
    console.error('Payment intent creation error:', error);
    throw error;
  }
};

Payment Method Setup:

// Set up payment method for AI agent
const setupPaymentMethod = async (customerId, paymentMethodId) => {
  try {
    const paymentMethod = await stripe.paymentMethods.attach(paymentMethodId, {
      customer: customerId
    });
    
    // Set as default payment method
    await stripe.customers.update(customerId, {
      invoice_settings: {
        default_payment_method: paymentMethodId
      }
    });
    
    return paymentMethod;
  } catch (error) {
    console.error('Payment method setup error:', error);
    throw error;
  }
};

Authorization and Limits

User Authorization:

// Handle user authorization for AI agent transactions
const handleUserAuthorization = async (userId, agentId, limits) => {
  try {
    const authorization = {
      user_id: userId,
      agent_id: agentId,
      max_amount: limits.maxAmount,
      max_transactions: limits.maxTransactions,
      time_limit: limits.timeLimit,
      authorized_at: new Date(),
      expires_at: new Date(Date.now() + limits.timeLimit * 24 * 60 * 60 * 1000)
    };
    
    // Store authorization
    await storeAuthorization(authorization);
    
    return authorization;
  } catch (error) {
    console.error('Authorization error:', error);
    throw error;
  }
};

// Check authorization before transaction
const checkAuthorization = async (userId, agentId, amount) => {
  try {
    const authorization = await getAuthorization(userId, agentId);
    
    if (!authorization) {
      throw new Error('No authorization found');
    }
    
    if (new Date() > authorization.expires_at) {
      throw new Error('Authorization expired');
    }
    
    if (amount > authorization.max_amount) {
      throw new Error('Amount exceeds authorization limit');
    }
    
    return true;
  } catch (error) {
    console.error('Authorization check error:', error);
    throw error;
  }
};

Handling Webhooks and Order Management

Webhooks are essential for keeping AI agents informed about payment status and transaction updates.

Webhook Implementation

Payment Status Webhooks:

// Handle payment status webhooks
app.post('/webhooks/stripe', express.raw({type: 'application/json'}), (req, res) => {
  const sig = req.headers['stripe-signature'];
  let event;

  try {
    event = stripe.webhooks.constructEvent(req.body, sig, process.env.STRIPE_WEBHOOK_SECRET);
  } catch (err) {
    console.log(`Webhook signature verification failed.`, err.message);
    return res.status(400).send(`Webhook Error: ${err.message}`);
  }

  // Handle the event
  switch (event.type) {
    case 'payment_intent.succeeded':
      handlePaymentSuccess(event.data.object);
      break;
    case 'payment_intent.payment_failed':
      handlePaymentFailure(event.data.object);
      break;
    case 'payment_intent.requires_action':
      handlePaymentActionRequired(event.data.object);
      break;
    default:
      console.log(`Unhandled event type ${event.type}`);
  }

  res.json({received: true});
});

// Handle payment success
const handlePaymentSuccess = async (paymentIntent) => {
  try {
    // Update order status
    await updateOrderStatus(paymentIntent.metadata.order_id, 'paid');
    
    // Notify AI agent
    await notifyAIAgent({
      type: 'payment_success',
      payment_intent_id: paymentIntent.id,
      order_id: paymentIntent.metadata.order_id,
      amount: paymentIntent.amount
    });
    
    // Process order fulfillment
    await processOrderFulfillment(paymentIntent.metadata.order_id);
  } catch (error) {
    console.error('Payment success handling error:', error);
  }
};

Order Management:

// Order management for AI agent transactions
const createOrder = async (transactionData) => {
  try {
    const order = {
      id: generateOrderId(),
      agent_id: transactionData.agentId,
      user_id: transactionData.userId,
      product_id: transactionData.productId,
      quantity: transactionData.quantity,
      amount: transactionData.amount,
      currency: transactionData.currency,
      status: 'pending',
      created_at: new Date()
    };
    
    // Store order
    await storeOrder(order);
    
    // Create payment intent
    const paymentIntent = await createPaymentIntent({
      ...transactionData,
      orderId: order.id
    });
    
    return { order, paymentIntent };
  } catch (error) {
    console.error('Order creation error:', error);
    throw error;
  }
};

// Update order status
const updateOrderStatus = async (orderId, status) => {
  try {
    await updateOrder(orderId, { status, updated_at: new Date() });
    
    // Notify AI agent of status change
    await notifyAIAgent({
      type: 'order_status_update',
      order_id: orderId,
      status: status
    });
  } catch (error) {
    console.error('Order status update error:', error);
    throw error;
  }
};
