The Duplicate Check option prevents the same product from being ordered again using the same credit card. This is primarily used in trial subscriptions to prevent customers from ordering the same product multiple times with the same payment method. You can configure this in your account settings under Settings > Account settings.

With Duplicate Check on, Admoji rejects a new order in two cases:

• The same customer already has an approved order with any of the same products in the last 6 hours. The order fails with REF:0004 Duplicate order.

• The same card (same BIN and last 4 digits) bought the same product in the last 30 minutes, even under a different customer. This check applies to sales paid by card with an amount above zero, and the order fails with REF:0008 Duplicate card order.

How to Configure Duplicate Checking

1. Open Settings by clicking your account card (logo and account name) at the top of the sidebar.

2. Click the Account settings button in the organization preview section.

3. Click the Personal Information tab.

4. Toggle the Duplicate Check switch to enable or disable.

5. Click Save to apply your settings.
