Accept a payment

Before you start

• Make sure that you have completed Sign up and received a Trustly test account.
• If you have a native app implementation, integrate Trustly SDKs.

Deposit flow

In a typical Deposit flow:

1. Your customer enters the amount for payment in your checkout.
2. Your system sends an API call to Deposit .
3. Trustly responds with a checkout URL and OrderID.
4. Your system redirects the customer to the Trustly checkout where they log in to their bank and authorise the payment.
5. The customer will be redirected from the Trustly checkout to SuccessURL specified in the deposit API call.
6. Depending on the outcome, Trustly may send these notifications:
   • Cancel notification if the checkout process is interrupted.
   • Pending notification when the customer has completed the checkout process.
   • Account notification Trustly sends information about the bank account used in this order.
   • Credit notification when the payment has arrived at your Trustly account.
   • Debit notification if the transaction fails after the credit notification is sent.

Note: Account, Pending, Credit notifications can arrive in any order. The Account notification is not enabled by default. Contact Trustly Integration Support, if you need it.

7. Your system responds to the received notifications.

Step 1: Integrate your system with Trustly

Develop business logic according to the deposit flow.

1. Make sure that your integration follows security requirements. See Security.
2. When a customer chooses Trustly in your checkout, your system calls Deposit.
3. Integrate Trustly Express. See Trustly Express API.
4. When Trustly responds with a Trustly URL, your system presents the URL to the customer to select a bank for making the deposit.
5. Make sure that your integration logs and handles error codes that are returned from API calls. See Error handling.
6. Make sure that your integration responds correctly to notifications that Trustly may send out.

Step 2: Design service presentation

When your integration presents a Trustly URL to customers, the presentation must follow Trustly checkout guidelines.

Step 3: Do acceptance testing

Prior to going live, the Trustly Integration Specialist will perform Acceptance testing. Make sure your integration has passed all test cases, including:

• Deposit API calls
• Built-in test cases of acceptance testing: D1 to D5, and G1 to G3.
• Verify that your integration has correct responses to notifications. See Notification tool.

Step 4: Verify and go live

Follow the instructions to go live.
