Adyen is our backup credit card processor.
In 2021, we updated our Adyen code to use their 'Checkout' integration, version 4. Checkout integration sources Adyen-hosted JS on our payments page and renders payment fields in the same form as the donor data, encrypting the data before submitting it to our server. We are using the 'components' style Checkout integration rather than the 'drop-in' style. Both styles use the same Adyen JS objects, but with components we instantiate a slightly lower-level JS object that is specific to the payment method.
A month after we deployed our new integration, Adyen released Checkout version 5 with some breaking changes and a simplified control flow. We have not made plans to update to version 5.
All calls to the Adyen API are routed through the SmashPig library. There are PaymentProcessor subclasses for each payment method.
Documentation for the former (Hosted Payment Pages) integration is at https://www.mediawiki.org/wiki/Fundraising_tech/Adyen
Available with payment_method=rtbt&country=NL The Checkout UI has a dropdown of available banks. This is gotten with an api call to get available payment methods
- Implemented using https://docs.adyen.com/payment-methods/apple-pay/web-component
- Using "own certificate" approach

Recurring Adyen donations are tokenized and are charged on our schedule by the SmashPig Civi extension's recurring payment charge job. Adyen recurring donations require two identifiers:
- Standard payment token, stored in the civicrm_payment_token table and called recurring_payment_token in queue messages and SmashPig parameters, referred to as 'storedPaymentMethodId' in the Adyen API
- Shopper identifier, stored in civicrm_contribution_recur. and called processor_contact_id in queue messages and SmashPig parameters, referred to as shopperReference in the Adyen API
We continue to receive Adyen IPN messages in SOAP format, as with the HPP integration. Because with Checkout we are able to capture card payments directly from payments-wiki, we have disabled the asynchronous capture flow that we were using with the HPP integration. Code for async capture is still present in SmashPig but is disabled in config/adyen/main.yaml by setting capture-from-ipn-listener: false. We should probably remove that code and config variable as part of T291448.
Adyen generates csv files on an irregular schedule 'whenever a payable batch closes' https://docs.adyen.com/reporting/settlement-detail-report . We process them with the wmf_audits drupal module that calls functions from SmashPig to parse the CSVs.
The DonationInterface Adyen Checkout adapter as of November 2021 sends duplicated messages to the Pending queue. It might not need to send any messages for card payments, as that queue is mostly used for pending transaction resolution, and that scenario is much less likely under Adyen Checkout due to us making the payment authorization and capture in the same HTTP request where we get the donor data.
The IPN listener sends 'RecordCaptureJob' messages to the Jobs-Adyen queue. These jobs combine information from the IPN message with information from the pending queue and send information to the donations queue.
