• Verify accounts - Complete verification before enabling payouts
• Use appropriate charge flow - Match your business model
• Handle platform fees - Application fees or separate transfers

Examples

Example 1: Create Connected Account

Question: "How do I create a connected account?"

Response:

import Stripe from 'stripe';
const stripe = new Stripe(process.env.STRIPE_SECRET_KEY!);

// Standard Account (seller manages everything via Stripe Dashboard)
export async function createStandardAccount(req, res) {
  try {
    const { email } = req.body;

    const account = await stripe.accounts.create({
      type: 'standard',
      email,
      metadata: {
        userId: req.user.id,
      },
    });

    res.json({ account });
  } catch (error) {
    res.status(500).json({ error: error.message });
  }
}

// Express Account (embedded onboarding, platform managed)
export async function createExpressAccount(req, res) {
  try {
    const { email, country } = req.body;

    const account = await stripe.accounts.create({
      type: 'express',
      email,
      country,
      capabilities: {
        card_payments: { requested: true },
        transfers: { requested: true },
      },
      business_type: 'individual', // or 'company'
      metadata: {
        userId: req.user.id,
      },
    });

    res.json({ account });
  } catch (error) {
    res.status(500).json({ error: error.message });
  }
}

// Custom Account (full platform control)
export async function createCustomAccount(req, res) {
  try {
    const { email, country } = req.body;

    const account = await stripe.accounts.create({
      type: 'custom',
      country,
      email,
      capabilities: {
        card_payments: { requested: true },
        transfers: { requested: true },
      },
      business_profile: {
        mcc: '5734', // Merchant category code
        url: 'https://seller-website.com',
      },
      tos_acceptance: {
        date: Math.floor(Date.now() / 1000),
        ip: req.ip,
      },
    });

    res.json({ account });
  } catch (error) {
    res.status(500).json({ error: error.message });
  }
}

// Retrieve account
export async function getAccount(req, res) {
  try {
    const { accountId } = req.query;

    const account = await stripe.accounts.retrieve(accountId as string);

    res.json({ account });
  } catch (error) {
    res.status(500).json({ error: error.message });
  }
}

// Update account
export async function updateAccount(req, res) {
  try {
    const { accountId, businessProfile } = req.body;

    const account = await stripe.accounts.update(accountId, {
      business_profile: businessProfile,
    });

    res.json({ account });
  } catch (error) {
    res.status(500).json({ error: error.message });
  }
}

// Delete account
export async function deleteAccount(req, res) {
  try {
    const { accountId } = req.body;

    const deleted = await stripe.accounts.del(accountId);

    res.json({ deleted });
  } catch (error) {
    res.status(500).json({ error: error.message });
  }
}

Account Types:

• Standard: Seller manages via Stripe Dashboard, platform has limited control
• Express: Platform manages with embedded onboarding, simpler setup
• Custom: Full platform control, custom UI, more complexity

    window.location.href = response.url;
  };

  return (
    <button onClick={handleOnboarding}>
      Complete Account Setup
    </​button>
  );
}

Example 5: Multi-Party Payment Split

Question: "How do I split payments between multiple sellers?"

Response:

// Split payment to multiple connected accounts
export async function createSplitPayment(req, res) {
  try {
    const { amount, sellers } = req.body;
    // sellers = [{ accountId: 'acct_1', amount: 50 }, { accountId: 'acct_2', amount: 30 }]

    // Create payment intent for total amount
    const paymentIntent = await stripe.paymentIntents.create({
      amount: amount * 100,
      currency: 'usd',
    });

    // After payment succeeds (in webhook), create transfers
    // This happens in the webhook handler
    const transfers = await Promise.all(
      sellers.map(seller =>
        stripe.transfers.create({
          amount: seller.amount * 100,
          currency: 'usd',
          destination: seller.accountId,
          metadata: {
            paymentIntentId: paymentIntent.id,
          },
        })
      )
    );

    res.json({ clientSecret: paymentIntent.client_secret, transfers });
  } catch (error) {
    res.status(500).json({ error: error.message });
  }
}

// Webhook handler for multi-party split
async function handlePaymentSucceeded(paymentIntent: Stripe.PaymentIntent) {
  // Get order details
  const order = await db.orders.findUnique({
    where: { paymentIntentId: paymentIntent.id },
    include: { items: { include: { seller: true } } },
  });

  // Group items by seller
  const sellerAmounts = new Map();
  order.items.forEach(item => {
    const current = sellerAmounts.get(item.seller.accountId) || 0;
    sellerAmounts.set(item.seller.accountId, current + item.amount);
  });

  // Create transfers to each seller
  const platformFeeRate = 0.1; // 10%

  for (const [accountId, amount] of sellerAmounts) {
    const sellerAmount = amount * (1 - platformFeeRate);

    await stripe.transfers.create({
      amount: Math.round(sellerAmount * 100),
      currency: 'usd',
      destination: accountId,
      metadata: {
        orderId: order.id,
        paymentIntentId: paymentIntent.id,
      },
    });
  }
}

Common Patterns

Check Account Capabilities

const account = await stripe.accounts.retrieve(accountId);

const canAcceptPayments = account.capabilities?.card_payments === 'active';
const canReceivePayouts = account.capabilities?.transfers === 'active';

Account Dashboard Link

const loginLink = await stripe.accounts.createLoginLink(accountId);
// Redirect seller to loginLink.url to access Stripe Dashboard

Handle Connect Webhooks

// Webhook events for connected accounts
switch (event.type) {
  case 'account.updated':
    // Account info changed
    break;
  case 'account.application.authorized':
    // OAuth authorization granted
    break;
  case 'account.application.deauthorized':
    // OAuth revoked
    break;
  case 'capability.updated':
    // Account capability changed
    break;
}

Common Errors

• Account not verified: Trying to charge unverified account

  • Solution: Complete onboarding and verification

• Capability not active: Requesting feature not enabled

  • Solution: Request capability and wait for activation

• Invalid account type: Using features not supported by account type

  • Solution: Use correct account type for your use case

• Transfer exceeds balance: Trying to transfer more than available

  • Solution: Check account balance before transfer

Notes

• Documentation covers latest Stripe API (2023+)
• Express accounts are recommended for most platforms
• Standard accounts have separate Stripe Dashboard access
• Custom accounts require more compliance work
• Platform fees are your revenue
• Instant payouts have additional fees
• File paths reference local documentation cache
