Testing And Go Live

Testing and Go-Live

This skill covers test mode, test payment methods, webhook testing, and the production launch checklist. Use it when building payment flows that need verification before going live, or when preparing to switch from test to production.

When to use this skill

• You need to test card success/decline scenarios, subscription renewals, or regional payment methods.
• You're setting up webhook testing locally or in a staging environment.
• You're preparing to launch to production and need a go-live checklist.
• You want to verify that test and live environments are properly isolated.
• You're copying products from test to production.

Core concepts

Test vs. live mode: Dodo Payments maintains two completely separate environments. Each has its own base URL, API keys, webhooks, products, customers, and transactions. Data does not carry over between them.

• Test mode: https://test.dodopayments.com
• Live mode: https://live.dodopayments.com

Each environment requires separate API keys issued from the dashboard. The SDK defaults to live_mode if you don't specify environment, which is a real footgun in development.

Test payment methods: Dodo documents specific card numbers, VPAs, and payment method scenarios for testing. These only work in test mode.

Webhook testing: The CLI provides commands to listen for webhooks locally and trigger test events without making real payments.

Setting up test mode

Always explicitly set environment: 'test_mode' during development. The default is live_mode.

import DodoPayments from 'dodopayments';

const client = new DodoPayments({
  bearerToken: process.env.DODO_PAYMENTS_API_KEY,
  environment: 'test_mode', // REQUIRED — defaults to 'live_mode'
});

from dodopayments import DodoPayments

client = DodoPayments(
    bearer_token=os.environ.get("DODO_PAYMENTS_API_KEY"),
    environment="test_mode",  # defaults to "live_mode"
)

client := dodopayments.NewClient(
    option.WithBearerToken("dodo_test_..."),
    option.WithEnvironmentTestMode(), // defaults to WithEnvironmentLiveMode()
)

Get your test API key from the Dodo dashboard. Test keys are prefixed dodo_test_.

Test payment methods

Card success and decline scenarios

Use these card numbers in test mode. The expiry can be any future date; the CVC can be any three digits.

Subscription renewal failure

To test subscription renewal failures, use this card:

UPI (India)

Test UPI success and failure with these VPAs:

BNPL, wallets, and regional methods

BNPL, Apple Pay, Google Pay, and European payment methods (Giropay, iDEAL, Bancontact) are available in test mode. Exact test scenarios vary by method. Refer to the Testing Process documentation for the current test matrix.

Testing subscription renewals

To force a subscription to renew on a specific date without waiting, update the next_billing_date:

await client.subscriptions.update('sub_123', {
  next_billing_date: '2026-05-03T00:00:00Z',
});

client.subscriptions.update(
    'sub_123',
    next_billing_date='2026-05-03T00:00:00Z'
)

// NextBillingDate is param.Field[time.Time], not a string. Passing a string
// literal compiles to param.Field[string] and will not type-check.
client.Subscriptions.Update(ctx, "sub_123", dodopayments.SubscriptionUpdateParams{
    NextBillingDate: dodopayments.F(time.Date(2026, time.May, 3, 0, 0, 0, 0, time.UTC)),
})

This immediately schedules the renewal. If you used the subscription-renewal-failure card, the failed charge emits payment.failed and the affected subscription enters on_hold, which emits subscription.on_hold.

Webhook testing

The CLI ships separately from the SDKs:

npm install -g dodopayments-cli
dodo login

dodo login opens the API Keys page, accepts a pasted key, and asks whether it is Test Mode or Live Mode. One key of each can stay authenticated at the same time.

Listen for webhooks locally

dodo wh listen http://localhost:3000/webhook

This forwards real test-mode events to your local URL over an outbound relay. It is not a tunnel: nothing listens publicly and no URL is printed for you to paste into the dashboard. If you need a registerable HTTPS URL, use ngrok instead — that flow is described in the webhook-integration skill.

Two constraints to know before running it:

• A Test Mode key is required. Live Mode keys are not supported by the listen flow.
• The URL argument is required in direct mode. Bare dodo wh listen only works inside the interactive TUI as /wh listen, which opens a wizard.

Events arriving this way carry valid signatures, so verify them normally with webhooks.unwrap().

Trigger mock webhook events

dodo wh trigger payment.success http://localhost:3000/webhook

Sends a realistic mock payload for a chosen event. It runs offline and works even while logged out — which is the tell for the part that matters: these payloads are unsigned. unwrap() rejects them because there is no valid signature to verify.

Use unsafeUnwrap() for triggered events only, and never on an endpoint that also receives real traffic. Event names are <category>.<event>, for example payment.success, subscription.active, or dispute.opened.

As with listen, both arguments are required in direct mode; /wh trigger inside the TUI opens a wizard instead.

Webhook signature verification

Covered in the webhook-integration skill. Verify every webhook that arrives over the network, in test mode as well as live. The single exception is the unsigned payloads produced by dodo wh trigger above.

Copying products from test to live

Products are environment-specific. You cannot reuse a test product ID in production. Instead, recreate the product in live mode or use the dashboard to export and reimport.

Manual approach:

1. Note the product details (name, price, tax category, etc.) from test mode.
2. Create a new product in live mode with the same configuration.
3. Update your code to use the new live product ID.

Programmatic approach:

Fetch the product from test mode, extract its configuration, and create it in live mode:

// In test mode
const testClient = new DodoPayments({
  bearerToken: process.env.DODO_PAYMENTS_API_KEY,
  environment: 'test_mode',
});
const testProduct = await testClient.products.retrieve('pdt_test_123');

// In live mode
const liveClient = new DodoPayments({
  bearerToken: process.env.DODO_PAYMENTS_API_KEY,
  environment: 'live_mode',
});
const liveProduct = await liveClient.products.create({
  name: testProduct.name,
  price: testProduct.price,
  tax_category: testProduct.tax_category,
  // ... other fields
});

Go-live checklist

Before switching to production, verify each item:

Business and compliance

• KYC (Know Your Customer) verification is complete in the Dodo dashboard.
• Business verification is approved.
• Your business details are correct in the dashboard.

API and keys

• You have live API keys from the dashboard (prefixed dodo_live_).
• You've rotated or revoked any test keys that were accidentally committed.
• Your code uses environment: 'live_mode' (or omits it, since live is the default).

Webhooks

• Your webhook endpoint is publicly accessible over HTTPS.
• You've updated the webhook URL in the dashboard to your production domain.
• You've updated the webhook secret in your environment variables.
• Your webhook handler verifies signatures using client.webhooks.unwrap() or the standardwebhooks package.
• You've tested the webhook flow end-to-end in production (or a staging environment with live keys).

Products and checkout

• All products are created in live mode (not copied from test).
• Your checkout code uses live product IDs.
• Return URLs point to your production domain.
• Tax categories are correct for your products.

Monitoring and support

• You have monitoring in place for payment failures, webhook delivery, and API errors.
• You know how to access the Dodo dashboard to view transactions and disputes.
• You have a plan for handling refunds and chargebacks.

Common mistakes

Leaving environment unset

The SDK defaults to live_mode. If you forget to set environment: 'test_mode' during development, your test code will hit production and create real charges.

// WRONG — this hits live mode
const client = new DodoPayments({
  bearerToken: process.env.DODO_PAYMENTS_API_KEY,
});

// CORRECT
const client = new DodoPayments({
  bearerToken: process.env.DODO_PAYMENTS_API_KEY,
  environment: 'test_mode',
});

Reusing test product IDs in production

Test and live environments are completely separate. A product ID from test mode does not exist in live mode. Always create new products in live mode or use the dashboard to migrate them.

// WRONG — pdt_test_123 does not exist in live mode
const session = await liveClient.checkoutSessions.create({
  product_cart: [{ product_id: 'pdt_test_123', quantity: 1 }],
});

// CORRECT — use a live product ID
const session = await liveClient.checkoutSessions.create({
  product_cart: [{ product_id: 'pdt_live_456', quantity: 1 }],
});

Forgetting to reconfigure webhooks for production

Test and live modes have separate webhook endpoints and secrets. If you copy your test webhook configuration to production without updating the URL and secret, webhooks will fail or go to the wrong place.

• Update DODO_PAYMENTS_WEBHOOK_KEY in production environment variables.
• Update the webhook URL in the dashboard to your production domain.
• Test webhook delivery in production.

Not verifying webhook signatures in production

Always verify webhook signatures using client.webhooks.unwrap() or the standardwebhooks package. Never trust a webhook without verification, even if it came from Dodo.

// WRONG — no verification
app.post('/webhook', (req, res) => {
  const event = req.body;
  handleEvent(event);
  res.json({ received: true });
});

// CORRECT
app.post('/webhook', async (req, res) => {
  try {
    const unwrapped = client.webhooks.unwrap(req.body.toString(), {
      headers: {
        'webhook-id': req.headers['webhook-id'] as string,
        'webhook-signature': req.headers['webhook-signature'] as string,
        'webhook-timestamp': req.headers['webhook-timestamp'] as string,
      },
    });
    handleEvent(unwrapped);
    res.json({ received: true });
  } catch (error) {
    res.status(401).json({ error: 'Invalid signature' });
  }
});

Mixing test and live keys

Test keys (prefixed dodo_test_) only work with https://test.dodopayments.com. Live keys are issued per mode from the dashboard. Using a test key with live mode will fail with an authentication error.
