Elavon Payment Gateway - Subscriptions API

10 steps
Create subsciptions for automatic payments. Official Integration Guide Official API reference
  1. Create subscription plan , that you are going to subscribe the shopper (customer) to.
  2. Create the shopper itself, in order to subscribe to the plan.
  3. Create payment method session , in order to prepare a chargable stored card. In this request you can specify if you would like to use lightbox / fields or redirect as a parameter.
  4. If you are using lightbox / fields asign the sessions' id to the object's constructor in javascript. In case of redirect , you will need to redirect the user to the URL returned in the previous Create payment method session request.
  5. Wait for return url / Javascript event call. You won't be able to use Notifications for this step, as they are not generated on stored card creation.
  6. Retrieve payment method session and store the stored card's id for later use.
  7. Create subscription with the stored card's id. You will need to store the subscription id so you can connect transactions to it, retrieve or update it if later the customer want to cancel its subscription.
  8. Wait for notification to confirm successful charges or to catch failed ones.
  9. Get the transaction information by Retrieve Transaction using the transaction ID included in the notification. You will need to match transactions using the subscription field and the stored id.
  10. Process your order based on transaction and subscription status.
Good to know & Good to Go
  • Make sure to not solely rely on the JavaScript events when checking for transaction status. It is highly recommended to set up webhook notifications and process transaction status based on them.
  • You will need Processor Id, Public Key, Private Key, and Merchant Alias. . You can find and generate test credentials from the Elavon Sandbox Account Form.
  • You will need to send your authentication information in each call. You can read more about the details Here .
  • Your base URL is either https://uat.api.converge.eu.elavonaws.com/ for the sandbox API or https://api.eu.convergepay.com/ for the production API. It is also provided at each API endpoint's description.
  • The best practice for handling the notifications is to not manually check, but rather to set up webhook notifications.
  • You should store response data in your backend's database while implementing different steps of payment, you would likely need a value from a previous call, e.g. Order ID from Create Order.
  • Please note in Subscriptions there is no ThreeDSecureV2 on transactions, hence Liability is always on Merchants. This is not an Elavon thing, this is the Rules and Regulations of the card schemes.
  • Do not mix Payment Session and Payment Method Session. They are not the same.
    • You can use the customReference field to uniquely identify subscriptions within notifications.
