1.9. Recurring Sale

Introduction

Recurring (Rebill) Sale is a type of transaction in which funds are debited from the Payer’s side to the Connecting Party’s bank account with previously saved cardholder data. Recurring sale transaction can be initiated manually on Payer’s behalf (this simplifies the payment process for the Payer) or automatically at certain intervals by Connecting Party (i.e. as a subscription model). Payer does not have to re-enter card information, Connecting Party uses Card reference ID to authorize payment. The necessity of Payer’s 3DS check and submit of card security code (CVC, CVV, etc) for recurring sale transactions is determined by bank account settings and related to Connecting Party business type.

See terms definitions (Connecting Party, 3DS Method, etc) in Glossary.

Recurring payments are made in three steps:
1. Initial payment – make initial payment to verify and authorize the Payer’s card. Any transaction type with present cardholder data will work as initial payment - sale, preauth, transfer, etc.
2. Card registration – get Card reference ID and register Payer’s card in Payer’s profile. Card registration requires initial payment to be in final status.
3. Recurring sale – process recurring sale transaction using Card reference ID.

Note

Initial payment transaction type and implementation depends on Connecting Party business model. Please contact Neogate support team to get relevant integration Use-Case for initial payment.

(1) To implement Card registration and get Card reference ID see /api/v2/create-card-ref/.
(4) To implement Card information request by Card reference ID see /api/v2/get-card-info/. The contents of response to this request can be used to show information about previously used card to Payer or to update Connecting Party database. This request can be made anytime if Connecting Party has Card reference ID.
(6) Recurring payment can be initiated by Connecting Party based on internal business model or Payer’s request.
(8, 9) Connecting Party sends request to the Payer to submit the CVV/CVC (Card Verification Value/Code), if it is required for selected processing channel.
(10) To initiate recurring sale transaction see /api/v2/make-rebill-sale/. See 3DS Decision Making Schema and 3DS Implementation Scenarios to correctly implement possible 3DS scenarios.
(12) To implement callback with final status handling see Connecting Party Callbacks.
(14) To implement order status see /api/v2/status/. Status should be requested multiple times with 3-5 seconds interval until final status will be received in response.
(16) Results of operation can be sent by Connecting Party based on internal business model or Payer’s request.

Connecting party has to implement all steps marked in green and purple. Below are the description for steps which reference specific API commands according to the step ID:

(1) To implement order status request see /api/v2/status/. Status should be requested multiple times with 3-5 seconds interval until final status will be received in response.
(4) If html and redirect-to fields are present, see Simplified authentication flow with html page.
(5) The same as point (1).

Note

The 3DS decision making schema is showcasing 3DS being initiated and performed by Payment Gateway. For other 3DS implementation scenarios, see 3DS Overview

Non3D Flow

Sale transaction should be considered as non3D (no 3DS authentication) if all conditions are met:

1. Steps 1-2-(5)-6 of 3DS decision making schema were followed.
2. tds_status, html and redirect-to parameters were not present.
3. Transaction received final status (approved, declined, error, filtered).

Note

Please note that transaction status “unknown” might appear for both 3DS and non3D transactions. See details in Statuses.

(1) and (2) To implement order status request see /api/v2/status/.
(9) To implement final redirect see Final redirect.
(10) The HTML wait page on Connecting Party side can have custom design and should communicate with Connecting Party server as described on the diagram.
(15) and (16) The same as point (1) and (2).
