How It Works

Checkout Flow:

API Call: Client sends priceId and plan name
Customer Creation: If first subscription, creates Dodo Payments customer
Session Creation: Dodo Payments checkout session created with:
- Subscription mode
- Card payment method
- Success/cancel redirect URLs
- User metadata
Redirect: User redirected to Dodo Payments checkout page
Payment: User enters payment details on Dodo Payments
Webhook: Dodo Payments sends webhook to create subscription in database
Redirect Back: User redirected to success URL

Redirect URLs:

Success: https://www.wiseyield.co/dashboard/billing?success=true
Cancel: https://www.wiseyield.co/pricing?canceled=true

Dodo Customer:

First checkout creates Dodo Payments customer
Customer ID stored in users.dodoCustomerId
Subsequent checkouts reuse same customer

Use Cases

Start Subscription Checkout

async function subscribeToSeed() {
  const response = await fetch('/api/billing/create-checkout-session', {
    method: 'POST',
    headers: {
      'Authorization': `Bearer ${apiKey}`,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({
      priceId: process.env.NEXT_PUBLIC_DODO_SEED_PRICE_ID,
      plan: 'seed'
    })
  });

  if (!response.ok) {
    toast.error('Failed to start checkout');
    return;
  }

  const { url } = await response.json();
  window.location.href = url;
}

Upgrade Plan

async function upgradeToHarvest() {
  // Show confirmation
  const confirmed = confirm(
    'Upgrade to Harvest plan for €89/month?'
  );

  if (!confirmed) return;

  const response = await fetch('/api/billing/create-checkout-session', {
    method: 'POST',
    headers: {
      'Authorization': `Bearer ${apiKey}`,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({
      priceId: process.env.NEXT_PUBLIC_DODO_HARVEST_PRICE_ID,
      plan: 'harvest'
    })
  });

  const { url } = await response.json();
  window.location.href = url;
}

Choose Plan with Price Selector

async function checkoutWithPlan(planName) {
  const priceIds = {
    seed: process.env.NEXT_PUBLIC_DODO_SEED_PRICE_ID,
    sprout: process.env.NEXT_PUBLIC_DODO_SPROUT_PRICE_ID,
    harvest: process.env.NEXT_PUBLIC_DODO_HARVEST_PRICE_ID,
    grove: process.env.NEXT_PUBLIC_DODO_GROVE_PRICE_ID,
    summit: process.env.NEXT_PUBLIC_DODO_SUMMIT_PRICE_ID,
  };

  const priceId = priceIds[planName];

  if (!priceId) {
    toast.error('Invalid plan selected');
    return;
  }

  const response = await fetch('/api/billing/create-checkout-session', {
    method: 'POST',
    headers: {
      'Authorization': `Bearer ${apiKey}`,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({ priceId, plan: planName })
  });

  const { url } = await response.json();
  window.location.href = url;
}

// Usage
await checkoutWithPlan('harvest');

Handle Checkout Success

// In /dashboard/billing page
function BillingPage() {
  const searchParams = useSearchParams();
  const success = searchParams.get('success');

  useEffect(() => {
    if (success === 'true') {
      toast.success('Subscription activated! Welcome to WiseYield.');

      // Refresh subscription data
      refreshSubscription();

      // Clear query param
      router.replace('/dashboard/billing');
    }
  }, [success]);

  return <div>Billing Dashboard</div>;
}

Best Practices

Store Product IDs: Keep Dodo Payments product IDs in environment variables for easy updates.

Show Confirmation: Display pricing and features before redirecting to checkout.

Handle Success: Check for ?success=true query param on return URL to show confirmation.

Loading State: Show loading indicator while creating checkout session.

Don’t Hardcode Prices: Use Dodo Payments product IDs from environment variables to support different pricing in development/production.

Test Mode: Dodo Payments checkout runs in test mode if using test API keys. Use test cards for development.

Webhook Required: Subscription won’t activate without webhook endpoint configured. Ensure /api/webhooks/dodo is set up.
