Audience This is a technical manual aimed at IT personnel involved in integrating merchants' systems with those at Adyen. The latest version of this document is available here: https://support.adyen.com/links/documentation General Tips/Warnings Defensive Programming Adyen strongly recommends the use of “defensive programming” when integrating with the Adyen Services. This implies that automated decisions programmed into your systems should be defaulted to non-delivery of products and services.
-
1. Introduction The purpose of this manual is to provide you with the ability to submit payments to the Adyen Payment System using an API rather than the Hosted Payment Pages (HPP). Due to strict industry regulations the API is only available to merchants who have full Payment Card Industry Data Security Standard (PCI DSS)1 compliance and fall into either the Level 1 or Level 2 categories. Furthermore, certain implementations of the API may require that you process minimum annual transaction volumes.
-
1.1. SOAP API SOAP is a communication protocol between two web services that uses XML for its message format. While you are free to choose your preferred method of integration, SOAP/REST., in most cases we recommend that you implement a SOAP integration to Adyen; SOAP implementations automatically handle a number of edge cases around encoding and validation that will result in a more robust integration.
-
3. Insert the payment variables, including your specifc account details and the relevant felds for the transaction type and click the submit button at the bottom of the page: 4. The browser communicates the values as HTTP Name/Value pairs and the response to the request is displayed in the browser: 1.3. Security (Authentication) To submit authorisation messages you must supply authentication credentials (username/password).
-
(CA) under “Settings” → “Users”.
-
2. Submitting API Payments SOAP API payments are submitted using the authorise action2. We will explain a simple credit card submission and in subsequent sections we will show you how to implement “Verifed by VISA / MasterCard SecureCode™” (3-D Secure) and Direct Debits. 2.1. Payment Fields 3 2.1.1. General Payment Fields • merchantAccount The merchant account for which you want to process the payment. • amount A container for the data concerning the amount to be authorised.
-
When comparing the SOAP felds and HTTP felds they are exactly the same. Typically it is just one feld with the same name, but more complex structures like the amount will be rendered in two individual felds: SOAP representation of an amount: EUR 500 REST representation of an amount: paymentRequest.amount.
-
2.2. Submitting API Modifcation Requests In addition to being able to perform modifcations via the Adyen Customer Area (CA), you may also use the API to initiate your modifcation requests. Modifcations are submitted using the same API, URL, WSDL, username and password as used for authorisations but using the modifcation specifc action. Please refer to the Adyen Merchant Integration Manual for details: https://support.adyen.com/links/documentation 2.3.
-
2.3.2. Additional Payment Fields There are two additional felds that will need to be passed in the authorisation request: • generationtime This feld is used to determine the validity of the payment request, any transactions submitted after 24 hours of this time will be refused. The format for this feld is the ISO 8601 format: YYYY-MM-DDTHH:mm:ss.sssZ . For example, “2013-11-15T13:42:40.428Z”.
-
2.3.5. Main Benefts • The credit card data is never readable to you. • Stateless, synchronous processing; the solution does not rely on a session token. • Uses the current API therefore all features are available: ◦ 3D Secure. ◦ Recurring. ◦ Installments. ◦ Airline / Level 3 Data. ◦ Risk/Fraud Detection. 2.4.
-
• resultCode The resultCode will be RedirectShopper. The paRequest and md felds should be included in a HTML form which needs to be submitted using the HTTP POST method to the issuerUrl. You must also include a termUrl parameter in this form which contains the URL on your site that the shopper will be returned to by the issuer after authentication. We recommend that the form is “self-submitting” with a fallback in case javascript is disabled. A sample form is shown below.
PAGE 16
2.5. AVS Address Verifcation Service (AVS) is a security feature that verifes the billing address of the card holder. It does so by comparing the numeric portions of the card holder's registered billing address to those entered by the shopper. AVS is only supported on a limited set of acquiring connections, card types, and only for a limited set of countries (United States, Great Britain and Canada).
-
REST billingAddress element: paymentRequest.card.billingAddress.city=Burbank&paymentRequest.card.billingAddress.street=Sou th+Buena+Vista+Street&paymentRequest.card.billingAddress.houseNumberOrName=17&paymentRequest. card.billingAddress.postalCode=91521&paymentRequest.card.billingAddress.stateOrProvince=CA&pa ymentRequest.card.billingAddress.country=US Please note, when testing the AVS results it is important to ensure that you are using one of the AVS test card numbers found here: https://support.adyen.
-
• APPROVED Please note: • There is a limit in characters of the Card Holder Name. The result may be: DECLINED : 05 : ISSUER_UNAVAIL • You may have to lower the risk score for non-alphabetic characters in the card holder name as the ':' character will trigger this check and may cause the payment to be declined with reason code "FRAUD". • An incorrect CVC or invalid expiry date will override the response code and always lead to a generic "DECLINE". 2.7.
-
2.8. Installments Some Acquirers, most notably in South America, support installments whereby the shopper is not charged the full payment amount in one charge, but is split at specifed intervals over a fxed period. Please contact the Adyen Support Team (support@adyen.com) for more details about the Acquirers that support this functionality. To support installments an additional object must be submitted in the authorise payment request: • installments A container for the installment data.
-
3. Idempotency In The Adyen API When interfacing with an API, dealing with failures and retries can be challenging. Adyen's API attempts to limit the impact of such a problem: • Asynchronous server-to-server notifcations inform you of the result of a request to the API. This is particularly useful in the eventuality that an authorisation response is missed, this may occur due to a timeout; please refer to section 8 for information regarding notifcations.
-
It is possible to bypass this check, by adding “idempotent-no-check-date” to the Pragma directive. Please note, the values in the Pragma directive are comma-separated. When processing a request idempotently, the response will contain a Last-Modifed header containing the date the original response was generated.
-
4. One-Click Payments One-Click Payments can be used to allow repeat/known shoppers to pay without re-entering their payment details. The shopper can be given the opportunity to store their payment details when they frst pay and is able to use these details for subsequent requests. For One-Click Payments the shopper will have to enter their credit card's CVC. Currently OneClick payments only work for Card payments.
-
5. Card Deposit (CFT) Card Deposit, also referred to as Card Funds Transfer (CFT), allows you to transfer funds directly onto a credit card. There are two methods to do this: 1. Refund an existing transaction for an amount exceeding the original transaction amount. This does not require you to know the card details, only a reference to the existing transaction. 2. Directly deposit funds on a card without an existing transaction.
-
5.3. CFT Notifcations Notifcations for card deposits, using both methods, are the same as for payments but the eventCode is REFUND_WITH_DATA, please refer to the Notifcations section in the Adyen Merchant Integration Manual for more information. As with regular payments you should check the success parameter to determine if the deposit succeeded.
-
6. Direct Debit Payments The European Payments Council (EPC) has mandated that as of 1st February 2014, all merchants that are currently processing, or planning to process, ELV or Incasso payments, must have implemented SEPA Direct Debits (DD). 6.1. US ACH Payments ACH (Automated Clearing House) payments are a form of Electronic Direct Debit used in the United States.
-
6.2. SEPA Direct Debits The Single Euro Payments Area (SEPA) is an EU payment-integration initiative for the simplifcation of bank transfers denominated in EUR. The European Payments Council (EPC) has mandated that as of 1st August 2014, all merchants that are currently processing ELV or Incasso (Dutch Direct Debit) payments, must have implemented SEPA Direct Debits (SDD). Please refer to the SEPA Migration Manual for more details on migrating ELV or Incasso payments to SDD: https://support.adyen.com/index.
-
6.2.3. SDD Notifcations Pending Notifcation The Pending notifcation is not enabled by default. Once enabled, the notifcation is sent out at the moment the payment is created. Please contact Adyen support (support@adyen.com) if you want to receive this additional notifcation.
-
Extended Authorisation Notifcation The extended notifcation is not enabled by default. Please contact Adyen support (support@adyen.com) if you want to receive the extended notifcation. 9913856361050084 Test Payment Reference SupportAdyenTest 2013-11-28 11:55:05.

-
6.4. Dutch Incasso Payments – deprecated 1 st August 2014 Dutch Incasso payments are a form of Electronic Direct Debit used in the Netherlands. The request is similar to a credit card request but rather than supplying a card object you supply a bankAccount object with the following felds: • bankAccountNumber A numeric feld for the Dutch bank account number which is either a 9-digit account number that complies with the Dutch elfproef5 or a Postbank number (see below).
-
6.4.3. Incasso Statement Text The consumer's statement will contain Adyen's bank account number and the name ADYEN. The actual account holder is the Adyen Client Management Foundation. Two further lines of information will be printed: • PspReference: 16 characters (Payment Reference). • Shopper Statement: 32 characters (Fixed or supplied as shopperStatement). Here is an example of an Incasso statement line that a consumer would see: 1323.94.
-
7. Boleto Bancário Boleto Bancário, often simply referred to as Boleto, is an ofine payment method used in Brazil . The consumer will take the Boleto form to an ATM, bank, an approved facility, or access their online banking system to complete the payment. Once the Boleto is paid, the bank will send Adyen a fle confrming that the payment was made, this usually takes one day, but it may occur up to 6 days after the payment.
-
/ 68 API Manual
-
7.2. Important Information Regarding Storage Of The Boleto PDF The Boleto contains sensitive information, namely the consumer's address and CPF; the Adyen URL is not available via a direct link but if you do decide to download the PDF and make it available on your systems, it is important to ensure that it is only available from a secure location, this is the recommended approach.
-
8. Notifcations Whenever a payment is made, a modifcation is processed or when a report is available for download, we will notify you of the event and whether or not it was performed successfully. Notifcations should be used to keep your backofce systems up to date with the status of each payment and modifcation. Notifcations are sent using either a SOAP call or using HTTP POST parameters to a server, that you host, that will receive and accept the notifcations.
-
◦ ADVICE_OF_DEBIT. ◦ CHARGEBACK. ◦ CHARGEBACK_REVERSED. For more information about Disputes please refer to the Merchant Manual. Please note that the success feld in a CHARGEBACK_REVERSED notifcation will always be set to true. Other Events ◦ REPORT_AVAILABLE. For more information please refer to the Adyen Reporting Manual. For specialised applications, such as recurring payments, other values are possible.
-
For SOAP notifcations a notifcation message is a container for an array of notifcation items, meaning that you may receive multiple notifcations within a single message. Please refer to Appendix S for a sample SOAP notifcation and response. Please refer to Appendix T for a sample REST notifcation and response. Please note that the eventCode AUTHORISATION does not necessarily mean that the authorisation is successful. The authorisation is successful if the success feld has the value true.
-
9. API Fault Codes In the following situations the Adyen platform does not accept or store a submitted request: • If the request does not pass validation. • If the request violates a security constraint. • If the request confguration constraint. Instead you will receive a SOAP Fault which will contain a description of the problem. Generally this will be handled as an Exception in your SOAP toolkit. Payment requests which are rejected with a SOAP Fault will not be charged.
