Merchant must capture these transactions within a time period in order to transfer the money from buyer's account to his own. This transaction can also be voided if a buyer cancels the order. Refund can be done after original pre-authorization is captured. Authorization Capture Period Please be aware that the maximum capture period for pre-authorization transactions can be shorter than 28 days. This period is not fixed and depends on several factors: - **Card Scheme Rules:** Varies based on agreements with card networks (e.g., Visa, Mastercard). - **Merchant Category Code (MCC):** Influenced by the specific MCC assigned to the merchant. - **Issuing Bank's Policy:** The final decision on the valid capture period rests with the card's issuing bank. --- #### Purchase *Purchase* doesn't need to be approved; funds are transferred in next settlement between issuer and acquirer banks. Generally expected between one and three days. Refund Note These transactions can be refunded via system (automatic one-click action), provided the original transaction did not involve installments. --- #### Capture Approved pre-authorization must be captured for the funds to be transferred form buyer's card to merchant account. This action can be done through merchant account interface or via an API call. A lesser amount than an original authorization amount can be captured as well, ie. a merchant can make partial delivery of goods and/or services. These transactions can be refunded via system (if transaction is not approved with installments). Important: Capture must be completed within 28 days or less (see [Authorization](/v1/docs/transaction-types#authorization)), otherwise the pre-authorization will be automatically voided. --- #### Refund Approved *purchases* and *captures* can be refunded within a period of 180 days or less. You can initiate this action either through your *merchant account interface* or via an *API call*. Refunds are typically necessary when a merchant cancels an order after the transaction has settled, or when a buyer is not satisfied with the delivered goods or services. In most cases, you can issue refunds for a lesser amount than the original authorization. However, please be aware that restrictions may apply for certain card types or transactions, depending on the policies of the acquiring bank. **Refund Policy** 1. **Refund Period:** Approved purchases and captured funds are eligible for refund for up to **180 days** from the transaction date. Please note that the window for **automated refunds** processed through the Monri system may be shorter, as this period is ultimately determined by the specific internal policies of the acquiring bank. 2. **Installment Transactions:** Transactions involving installments **are not eligible for automated refunds through the Monri system**. To process a refund for such transactions, a direct request must be submitted to the acquiring bank. For additional details or assistance, please reach out to the acquiring bank responsible for processing that specific transaction. **Multiple refunds** Some acquiring banks allow multiple consecutive refunds on the same completed authorization (on a Capture or Purchase transaction). Important: The total sum of all refunds cannot exceed the original completed amount." --- #### Void Approved authorization can be voided within 28 days if buyer or merchant cancels the order. This action can be done through merchant account interface or via an API call. **Partial Void** A *partial void* is also available, allowing an approved authorization (pre-authorization) to be partially cancelled. Important: The ability to perform more than one partial void on the same pre-authorization is dependent on your/merchants acquiring bank's specific rules. Please refer to your/merchants acquiring bank for confirmation. Important: The total sum of all voids cannot exceed the completed amount of the original pre-authorization transaction." *Transaction Type* A two-step transaction process where funds are first reserved and then collected. - **Step 1: Authorization (Internal: Authorization)** - **Action:** Also known as **Pre-authorization**. It verifies card validity and reserves (blocks) the specific amount on the cardholder’s account. - **Status:** Funds are not yet transferred, only "held" for a specific period (usually 7–30 days). - **Step 2: Capture (Internal: Completion/Settlement)** - **Action:** Also known as **Post-authorization**. The process of confirming and collecting the previously reserved funds. - **Result:** Initiates the actual transfer of money from the cardholder to the merchant. - **Key Benefit:** Allows merchants to verify stock or service availability before final payment (e.g., in hotels, car rentals, or e-commerce).
