Testing

What should I test as I integrate Stripe?

When using Stripe.js, you should ensure the following:

  • The card number, expiration, CVC and amount are set correctly in createToken.
  • In the response handler for createToken, card errors are handled and displayed properly.
  • Only a valid token is passed to your server as part of payment form submission.
  • Sensitive card details (number, expiration and CVC) are not included in form data submitted to your server.

In server-side code, you can test the following:

  • All values submitted from the payment form are valid and expected.
  • All API errors are handled properly.
  • Relevant webhooks are handled correctly (more on how to test webhooks below).

Before you go live, verify your publishable and secret keys. You can see all your keys on your account page.

Account Settings

You can configure your decline settings in https://dashboard.stripe.com/account.

These allow you to decide whether a failing cvc_check or failing address_zip_check should cause the charge to be rejected. Perhaps surprisingly, even if these details are wrong, the charge can succeed; it's up to you decide what to do in that case.

Note that we don't have a setting for address_line1_check failures to cause a decline, as the data for this particular check tends to be pretty noisy.

We recommend leaving these settings at their defaults unless you have special requirements.

Logs

As you integrate and test Stripe, you may find it useful to view logs of your requests.

How do I debug JavaScript?

There are many tools for tracking down problems in your client side code. We recommend reading about the Chrome Web Inspector. Should you need it, you can also load a debug version of Stripe.js at https://js.stripe.com/v2/stripe-debug.js.

How do I test webhooks?

The Dashboard has a test feature built in. Navigate to your webhook settings and click Test Webhooks. You can select a type of webhook, and one of your test webhook URLs. If you don't have any test webhook URLs defined, you'll have to define one first.

If you don't have a server set up to receive webhooks but want to see example webhook requests, we suggest using a service like RequestBin to inspect the requests we send.

If you'd like to test subscription webhooks with live data, a useful trick is setting the subscription's trial_end attribute to a short time in the future. This ensures you don't have to wait a month to receive an invoice webhook.

Which card numbers should I use for testing?

In test mode, you can use these test cards to simulate a successful transaction:

Number Card type
4242424242424242Visa
4012888888881881Visa
4000056655665556Visa (debit)
5555555555554444MasterCard
5200828282828210MasterCard (debit)
5105105105105100MasterCard (prepaid)
378282246310005American Express
371449635398431American Express
6011111111111117Discover
6011000990139424Discover
30569309025904Diners Club
38520000023237Diners Club
3530111333300000JCB
3566002020360505JCB

In addition, these cards will produce specific responses that are useful for testing different scenarios:

Number Description
4000000000000077Charge will succeed and funds will be added directly to your available balance (bypassing your pending balance).
4000000000000010With default account settings, charge will succeed but address_line1_check and address_zip_check will both fail.
4000000000000028With default account settings, charge will succeed but address_line1_check will fail.
4000000000000036With default account settings, charge will succeed but address_zip_check will fail.
4000000000000044With default account settings, charge will succeed but address_zip_check and address_line1_check will both be unavailable.
4000000000000101With default account settings, charge will succeed but cvc_check will fail if a CVC is entered.
4000000000000341Attaching this card to a Customer object will succeed, but attempts to charge the customer will fail.
4000000000000002Charge will be declined with a card_declined code.
4100000000000019Charge will be declined with a card_declined code and a fraudulent reason.
4000000000000127Charge will be declined with an incorrect_cvc code.
4000000000000069Charge will be declined with an expired_card code.
4000000000000119Charge will be declined with a processing_error code.

Additional test mode validation: By default, passing address or CVC data with the card number will cause the address and CVC checks to succeed. If not specified, the value of the checks will be null. Any expiration date in the future will be considered valid.

How do I test specific error codes?

Some suggestions:

  • card_declined: Use this special card number - 4000000000000002.
  • incorrect_number: Use a number that fails the Luhn check, e.g. 4242424242424241.
  • invalid_expiry_month: Use an invalid month e.g. 13.
  • invalid_expiry_year: Use a year in the past e.g. 1970.
  • invalid_cvc: Use a two digit number e.g. 99.

The full list of API error codes is available here.

How do I test accepting Bitcoin?

In test mode, you can use the following test emails (set on BitcoinReceiver objects) to test different edge cases. By default, a receiver will always be paid 3 seconds after creation.

Email Description
{any_prefix}+fill_never@{any_domain}Bitcoin are never sent to the receiver address.
{any_prefix}+fill_now@{any_domain}The next time that the receiver is retrieved after creation, it has been filled by bitcoin.

How do I test disputes?

In test mode, you can use the test card below to simulate a disputed transaction:

Number Description
4000000000000259With default account settings, charge will succeed, only to be disputed.

The following evidence, when submitted, will produce specific actions that are useful for testing the dispute flow:

Evidence Description
winning_evidenceThe dispute will be closed and marked as won. Your account will be credited the amount of the charge and related fees.
losing_evidenceThe dispute will be closed and marked as lost. Your account will not be credited.

How do I test sending transfers?

When sending third-party transfers in test mode, you can use these test bank accounts, tax IDs, and debit card numbers.

Test tax IDs

Pass in any name and one of these tax IDs (they work as both SSNs and EINs) for the desired recipient verification behavior.

Number Type
000000000Successful verification
111111111Unsuccessful verification (identity mismatch)

Test debit card numbers

You can attach these test debit card numbers to your recipient to test transferring to a debit card. These can only be used with test secret keys.

Number Type
5200828282828210MasterCard debit. Transfer will succeed.
4000056655665556Visa debit. Transfer will succeed.
4000056655665564Visa debit. Transfer will fail with a could_not_process code.

Test bank account numbers

There are various test routing and account numbers you can use to trigger certain events. These can only be used with test secret keys. When creating test transfers, you must use a test account number but you can use any valid US routing number.

Routing numbers

Number Type
110000000STRIPE TEST BANK US routing number

Account numbers

Number Type
000123456789Transfer will succeed.
