Subscriptions Integration Guide

Last updated:April 29, 2024

This Subscription Integration guide describes how you can schedule subscription payments. Like recurring payments, the money gets auto-debited from consumer's bank account to the merchant account in fixed time periods (e.g. weekly, monthly, quarterly, yearly). Similarly, money can be auto-credited using payouts. Subscription businesses benefit from the flexibility of creating different plans and pricing structures to meet market demands.

A subscription payment can be scheduled as a pre-authorization (PA), debit (DB) or credit (CD) transaction.

To collect card data, you must be PCI-DSS compliant. To minimize your compliance requirements, please use COMO World COPY&PAY Registration Tokens.

Transactions:

1. Store the payment data

Collect the customer payment information via COMO World COPY&PAY or Server-to-Server. With any of the options, please consider having a card-on-file agreement with the shopper. It is best to tokenize the card during the cardholder (CIT) initiated payment so that a merchant (MIT) agreement is in place for the future subscription payments.

Sample request:

2. Schedule a payment

Perform a server-to-server POST request with the registration id, payment type and the job schedule parameters which describes when and how often the transaction should be executed. For a complete reference of the scheduling job parameters, please check API Reference.

You can use the numerical allowed values to declare specific dates, months and days of the week for the subscription payment to be executed. The special characters allow for more advanced functionality. Please click the button below to see the table where we've outlined their general function and what their value means in each field.
