Authorize Payment

See the detailed API documentation for more information.

Why Authorize Payment is Important

The Authorize Payment call is a required called for all transactions, which transfers all consumer and order information to Riverty's system. The call triggers Riverty's Risk engine which when confirms the information provided is valid and that the constumer qualifies for the transaction. The authorization response informs whether the consumer and order are accepted by Riverty or not.

An Example

Astrid places the items into her Cart, and goes to the Checkout page and enters her name, email, national ID number, and address. She then selects Riverty 14 Day Invoice here desired payment method.

When she clicks the "Buy" button, the shop sends a POST call to the AUTHORIZE endpoint of the Riverty eCommerce API. This call contains the information Astrid entered above. The call passes all risk checks and responds "Accepted". Astrid is shown that the payment has been successful.

Now a reservation exists in Riverty’s accounts, in the merchant’s name, for the purchase price.

Different reference numbers may be used in the e-commerce/payment industries. To learn about our specific requirements for order/reference numbers, please refer to our dedicated References Explanation page.

Riverty classifies accepted authorizations as either "Reservations" or "Non-captured Orders". Without a follow-up action such as a VOID or Capture, Riverty will automatically cancel the order/reserved amount after 30-45 days.

If the client/webshop provides the option for consumers to send their package to a specific shipping address, it is required to send this information to Riverty. Failure to do so may result in liability or financial damage claims against the merchant in cases of fraud.

If a client or webshop offers a click-and-collect option for consumers to collect their packages from a physical store location, they are required to send the address information of that store to Riverty. Failure to do so may result in liability or financial damages in cases of fraud, which will be the responsibility of the client or webshop.

If the client/webshop provides the option for consumers to send their package to a pick-up point, it is required to send the pick-up point address to Riverty. Failure to do so may result in liability or financial damage in cases of fraud, which will be the responsibility of the client or webshop.

Riverty's current policy does not allow orders with a billing address from one country and a shipping address from another country. We only allow shipping addresses within the same country where the billing address is located.

Riverty provides a specific field for entering house number additions. Depending on the address format of each country, we kindly request that you consider providing the house number addition in this field.

Although the "House Number Addition" field is not mandatory according to our API documentation, many addresses in various countries can have a house number addition, such as "2nd floor," "Box 1," or "-C." If this specific field is missing in the checkout, customers may add the addition in the house number field.

We have a smart algorithm in place, but it is still possible that house number and house number addition cannot be processed correctly.

For instance, a Belgian address consists of:

  • Street Name: TESTSTREET
  • House Number: 15
  • House Number Addition: 2nd floor
  • Postal Code: 2000
  • City Name: Brussels
  • Country Name: Belgium

Riverty can only accept mail order/telephone order (MOTO) transactions from clients/partners who have signed the contract or addendum for MOTO processing. This is also known as the Riverty Call Center Setup, which involves whitelisting the client's call center or customer department IP address.

Riverty anticipates that merchants or partners will submit amounts with accurate values. However, in cases where rounding issues cannot be avoided, we offer the following flexibility:

  • A discrepancy of up to 1 cent per order line is acceptable for the grossUnitPrice.
  • The calculation of "grossUnitPrice = netUnitPrice + vatAmount" must remain accurate.
  • This 1 cent tolerance applies per order line, not per quantity ordered.
