Create Subscription Identifier


This section expects prior knowledge and understanding from the sections indicated below. Please note that these areas are essential to obtaining a successful response and notifying your server upon completion.

  • API Overview
  • API Key and Merchant ID
  • Live Payment Notification (LPN)


This API is used to create ad-hoc subscriptions, where you pass in the relevant subscription details generated on your system.

A subscription identifier is a temporary record held in the CyberCom Pay Checkout system that identifies subscriptions sent to the Subscriptions page for a particular item being subscribed too. Identifiers are setup for subscriptions using the createSubscriptionIdentifier API. You simply pass the item's details and the API will return the item's identifier. Then when a user clicks to subscribe, the corresponding identifier is sent to the Subscriptions page, where the items details (subscribers details, subscription price etc) are displayed.


The API takes the following parameters as either GET or POST data:

  • merchant_id - The merchant ID that can be found within the merchant console. (Compulsory)
  • api_key - The API Key associated with the merchant ID. This is used to authorise and identify the caller of the request. (Compulsory)
  • contract_id - The contract_id for the subscription plan to set up the identifier for (Compulsory)
  • td_email - The subscriber's email address (Compulsory)
  • td_first_name - The subscriber's first name (Compulsory)
  • td_last_name - The subscriber's last name (Compulsory)
  • td_address - The subscriber's address (Compulsory)
  • td_city - The subscriber's city (Compulsory)
  • td_country - The subscriber's country (Compulsory)
  • td_company - The subscriber's company (Optional)
  • td_suburb - The subscriber's suburb (Optional)
  • td_phone - The subscriber's phone number (Optional)
  • td_mobile - The subscriber's mobile number (Optional)

Please note that when you pass customer data into this API, the CyberCom Pay system creates a contact record, using the email address as a unique identifier. If you pass in data with the same email address to the createSubscriptionIdentifier API, CyberCom Pay will load the contacts data if it already exists in the database.

Test Code

Below is an example code that will work against a test section of the server. Although this is intended to simulate server behaviour, characteristics and responses are not always the same.

Please note that no transactions will be sent online and the server will not store any information from these requests. For more information on this, please see Testing Without An Account
