Testing

Simulate payments to test your integration.

In order to confirm that your integration works the way it should, you are able simulate all operations without moving any money. You can do this by creating and manipulating resources in test mode . Completing test checkout sessions can be done using test accounts.

How to use test accounts

When testing, please use your test API keys to create a checkout session and launch Smartpay checkout (for further details on authenticating your API requests see Authentication ). In test mode the payment is not processed by card networks or payment providers. It enables you to feel safe working on the integration without having to worry about actually being charged.

Test mode checkout will show a テスト中 banner on the top right corner so you can easily verify you are using test mode.

Test consumer account

To complete a test mode checkout you need a test user account. Please follow the instructions below to sign up as a test user to Smartpay.

Email address

Once you are redirected to Smartpay checkout, all you need to do is to use any email with a +test suffix, e.g. [email protected] to sign up, and it will immediately be regarded as a test account.

Phone number

When prompted for a phone number please provide a valid Japanese mobile number.
Smartpay verifies the shoppers' phone number by sending a one time password via SMS to the phone number specified during sign up. For test accounts however this one time password is not sent via SMS, it is already pre-filled for you on the form.

Card number

Your test Smartpay account will come with pre-configured card numbers so you can test all the different outcomes:

• Success: 4242 4242 4242 4242
• Hard decline: 4100 0000 0000 0019
• Soft decline: 4000 0000 0000 0119

For test consumers you will not be able to add your own card or use Apple Pay or Google Pay.
