About direct debit
General information about direct debit
Computop Paygate can combine electronic direct debits (ELV) in Germany with a block list check which offers high security at low cost: Paygate checks if the Customer's account number is black listed by major retailers. Additionally you can prevent fraud by setting sales limits per day, week or month which an account connection may not exceed.
Since there are substantially more accounts than credit cards, many Internet purchases are paid by direct debit. The direct debit process is unsafe for merchants without a block list check: in the case of SEPA direct debits there is no authorisation because it is not possible to carry out a credit rating on the account of the customer. Therefore there are frequently returned debit notes in the case of ELV due to lack of funds in accounts.
The block list check links the benefits of the direct debit with Paygate the security of a block list check and individual sales limits.
Transaction procedure of a direct debit payment on the Internet
In order to pay with a direct debit, the customer selects the Direct debit payment method at the Internet checkout and enters their account details. This Internet page is TLS encrypted to protect the account data during the transmission against tapping and manipulation. After the input Paygate checks if the account is blocked and if the sales limit for this account has been reached. After successful verification, Paygate draws direct debits from the customer's bank.
SEPA direct debit
With SEPA uniform rules for cashless payment transactions are effective since 1st February 2014. Therefore IBAN (International Bank Account Number) and BIC (Bank Identifier Code) are used as account data. With Paygate direct debits can be managed compliant to SEPA.
Time frames for chargebacks
Depending on the SEPA Mandate form there are different time frames during which the customer can trigger a chargeback.
• Authorised SEPA Mandates (at the POS with PIN/signature): maximum time frame during which the end-customer can trigger a return debit/chargeback is 8 weeks from the payment date.
• Unauthorised SEPA Mandates (eCommerce payments): maximum time frame during which the end-customer can trigger a return debit/chargeback is 13 months from the payment date.

Corporate PayPage
Paygate forms are framed as standard in white and grey. Merchants can customise the layout of the forms with the help of layout parameters. The simplest way to change the layout is to set the parameters for the background colour (BGColor), background image (BGImage) and the font (FFace). You can use XSL-templates to change the layout further:
In the case of direct debit payments you can change the parameter Template to create an individual layout for your PaySDD-form which exactly matches your shop layout. To this end your graphic designer can design an HTML-template in the shop-design based on XSLT (Extensible Stylesheet Language Transformation). Computop Helpdesk copies this XSLT-template to our Paygate Server. If you enter the name of your XSLT-file in the Template parameter, the Paygate form will appear in your layout.
For general information about XSLT see www.w3.org.
The subsequent conventions apply for the use of the Corporate Pay Page with XSLT:
File names
A XSL file designed by you defines your individual layout. The associated XML file contains the texts that are to be displayed on the form. Hence, multilingualism is easy. Always use your MerchantID in the names of the files.
XSL template: MerchantID_PaySDD.xsl
XML text file: MerchantID_PaySDD.xml
Sub-folder for images: Templates/imagesMerchantID
In order not to receive safety notices, please ensure that external image sources are retrieved via SSL.
In order to call the individual layout, use the ‘template’ parameter with your MerchantID and attach it unencrypted to the call of the Computop payment page, for example: https://www.computop-paygate.com/paysdd.aspx?MerchantID=IhreMID&Len=123&Data=ABCFED…ACEF&template=IhreMerchantID
Field names of the form
When implementing the text field for the IBAN, use the following values for the parameters ‘name’ and ‘id’:
Account holder: „AccOwner“
IBAN: „IBAN“
BIC: „BIC“
Bank (optional): „AccBank“
A text field for the input of the IBAN is then implemented as follows:
<input type="text" name="IBAN" id= "IBAN" value=""></input> |
Hidden Fields
The following hidden fields must be implemented so that the values can be passed on when sending the form:
MerchantID: „MerchantID“
Request length: „Len“
Request data: „Data“
Template: „Template“
Language: „Language“
Language selection
The language selection in form PaySDD.aspx is automatically based on the parameter Language. Other language areas are filtered out. If you wish to access the field of another language area e.g. with JavaScript, you can do so via the following path: template/language/@name.
XML structure
The ‘language’ parameter controls which section of the XML text file is read out. German ‘de’ is always used as standard.
The XML file should have the following basic structure:
<?xml version="1.0" encoding="UTF-16"?> </languages> <language name="de"> </language> <language name="en"> </language> </languages> |
With <xsl:variablename=““ select=“template/language/@name”/> you can directly address an XML language section from the XSL file.
For an overview of which parameters are rendered by the PaySDD, please examine the following structure (XSL file is rendered against the following XML string):
Dim strXML As String = "<?xml version='1.0' encoding='UTF-16'?>" & _ "<template pay='elv'>" & _ "<merchantID>"..."</merchantID>" & _ "<PayID>"..."</PayID>" & _ "<len>"..."</len>" & _ "<data>"..."</data>" & _ "<language>"..."</language>" & _ "<Border>"..."</Border>" & _ "<Background>"..."</Background>" & _ "<BGImage>"..."</BGImage>" & _ "<BGColor>"..."</BGColor>" & _ "<FFace>"..."</FFace>" & _ "<FSize>"..."</FSize>" & _ "<FColor>"..."</FColor>" & _ "<twidth>"..."</twidth>" & _ "<theight>"..."</theight>" & _ strCustomFieldsXML & _ "<URLBack>"..."</URLBack>" & _ "<AccOwner>"..."</AccOwner>" & _ "<IBAN>"..."</IBAN>" & _ "<PBAN>"..."</PBAN>" & _ "<BIC>"..."</BIC>" & _ "<Bank>"..."</Bank>" & _ "<template>"..."</template>" & _ "</template>" |
Since merchants use its own layout for the form, you do not require the layout parameter. However, it is possible after prior consultation with Computop to use the parameters for the transfer, e.g. the SessionID.
JavaScript
If JavaScript functions are desired, you must implement them in your template.
<script id=“clientEventHandlersJS“ language=“JavaScript“> if (document.SDDForm.IBAN.value.length > 34) { alert(„<xsl:value-of select=“/template/language/strJavaScript1“/>“); document.SDDForm.IBAN.focus(); } ... </script> |
Please do not use any external link to your JavaScript.
Link to Computop logo
Computop is obliged to provide the account holder information on which server he is on. Please implement a Computop logo like it is implemented on the standard form or display a small imprint link. You can download the Computop logo from www.computop.de/downloads.
Both items of information must refer to the Computop page impressum.aspx. This expects the ‘Data’ parameter, which is appended to the URL as in the following example.
impressum.aspx?data=<xsl:value-of select="/template/language/@name"/>|<xsl:value-of select="template/merchantID"/> |
Programming and testing the form
First design a HTML page with the layout for your payment page and initially save it for testing with the file extension .htm or .html. Open this file in the browser. Next, save this as an xsl file.
<?xml version='1.0' encoding="UTF-16"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="html" encoding="UTF-8"/> <xsl:template match="/"> <html> <head> <title>PaySDD Template</title> <script>Your JavaScript</script> </head> <body> <form action="https://www.computop-paygate.com/payinterim.aspx" methode="POST"> </form> </body> </html> </xsl:template> |
In order to read the texts from the XML file, first of all create your tags in the desired language sections with the texts:
<language name="de"> <strIBAN>IBAN</strIBAN> </language> |
Subsequently, replace the text in the HTML by a reference to the respective section in the XML file:
<xsl:value-of select="/template/language/strIBAN"/> |
In order to test your template, we request that you integrate the following lines in your XML file only for the test (before sending it to Computop) and afterwards to call up the XML file in a browser. If no error is displayed you can send your template and the image folder in a Zip file to Computop Helpdesk with a request to check and install it.
<?xml version="1.0" encoding="UTF-16"?> <?xml-stylesheet type="text/xsl" href="templatename.xsl"?> <template> <languages>please omit for your layout tests <language name="de"> </language> <language name="en"> </language> <languages>please omit for your layout tests </template> |
In order to get an overview of the versions, please include the date and version number in the name of your Zip file.
General parameters of the interface
The interface of the Paygate form is consistently paysdd.aspx for all connections. In order to make a direct debit payment via Paygate form, please use the following URL:
https://www.computop-paygate.com/paysdd.aspx |
This section explains the parameters which are the same for each connection. These values are always required, along with the special parameters explained in the following sections for each individual connection. The second table explains all response parameters which are also the same for all direct debit connections.
Notice: For security reasons, Computop Paygate rejects all payment requests with formatting errors. Therefore, please use the correct data type for each parameter. The following table describes the encrypted payment request parameters:

Please note that the Computop Paygate must have a finalized transaction status for the first initial action (authentication/authorisation). This does not apply to 3-D Secure authentications that are terminated by a timeout. The 3-D Secure Timeout status does not count as a completed status in which the ReqID functionality on Paygate does not take effect. Submissions with identical ReqID for an open status will be processed regularly. Notice: Please note that a ReqID is only valid for 12 month, then it gets deleted at the Paygate. | ||||||||

Response parameters for captures of direct debit payments
Credit with reference
Credits (refunds) are possible via a Server-to-Server connection. Paygate permits credits which relate to a capture previously activated by Paygate and allows merchants to carry out credits without a reference transaction. This section describes the processing of credits with reference transactions. If you refer to a capture for a Credit, the amount of the Credit is limited to the amount of the previous capture.
To carry out a credit with a reference transaction, please use the following URL:
https://www.computop-paygate.com/credit.aspx |
Notice: For security reasons, Computop Paygate rejects all payment requests with formatting errors. Therefore, please use the correct data type for each parameter. The following table describes the encrypted payment request parameters:
Key | REST | Format | CND | Description |
|---|---|---|---|---|
| BasicAuth.Username | ans..30 | M | MerchantID, assigned by Computop. Additionally this parameter has to be passed in plain language too. | |

RefNr | "referenceNumber": "..." | ns..30 | C | not with EVO: Merchant’s unique reference number |
| Amount | "amount": { "value": ...} | n..10 | M | Amount in the smallest currency unit (e.g. EUR Cent). Please contact the Computop Helpdesk, if you want to capture amounts <100 (smallest currency unit). |
| Currency | "amount": { "currency": "..."} | a3 | M | Currency, three digits DIN / ISO 4217, e.g. EUR, USD, GBP. Please find an overview here: A1 Currency table |
| ReqId | "requestId": "..." | ans..32 | O | To avoid double payments or actions (e.g. by ETM), enter an alphanumeric value which identifies your transaction and may be assigned only once. If the transaction or action is submitted again with the same ReqID, Computop Paygate will not carry out the payment or new action, but will just return the status of the original transaction or action. Please note that the Computop Paygate must have a finalized transaction status for the first initial action (authentication/authorisation). This does not apply to 3-D Secure authentications that are terminated by a timeout. The 3-D Secure Timeout status does not count as a completed status in which the ReqID functionality on Paygate does not take effect.

Credit without reference
Paygate can carry out Credits which do not relate to a previous capture. In this case the credit must be transferred to Paygate as a completely new payment transaction. Please contact the Computop Helpdesk for help in using the described additional functions.
Notice: Please note that credits without reference to a previous capture generate higher costs with your Acquiring Bank. If you are frequently unable to make reference to the capture you should agree this with your Acquiring Bank.
Notice: Credit without reference is only possible with a direct debit connection.

Reversal
Reversals are possible via a Server-to-Server connection. In order to cancel a direct debit payment via a server-to-server communication, please use the following URL:
https://www.computop-paygate.com/reverse.aspx |
Notice: Reverse.aspx does not only reverse authorisations, but any LAST TRANSACTION STAGE! If the last transaction was a capture, Reverse.aspx initiates the reverse, e.g. a credit. Therefore, the utmost caution is urged. Use is at your own risk. We recommend checking the transaction status with Inquire.aspx before using Reverse.aspx.
Notice: Cancellation is only possible with a direct debit connection.

Response parameters for reversals of direct debit payments
Batch processing via the interface
Basic information about using Batch files and about their structure can be found in the Batch Manager manual. Within batch processing not alle functions are available which are usually available for the online interface.
Batch calls and answers
This section describes the parameters which must be transferred within the data set (Record) for executing a direct debit payment and which information can be found within the response file about the payment status.
The possible actions per batch depend on the respective connection. In the case of direct connections all transactions including credit without reference are possible while cancellation and credit without reference are not possible with EVO Payment, InterCard and PPRO connections. In the case of PPRO the transactions are also purely sales transactions and so only sales and credit is possible here.
Following table gives an overview of all batch versions that are possible for a specific action and their specialities:
Description of the possible batch versions
The structure for a direct debit payment within a Batch file to be submitted is the following:
HEAD,<MerchantID>,<Date>,<Version> EDD,Authorize,<Amount>,<Currency>,<TransID>,(<RefNr>,)<AccOwner>,<IBAN>,<BIC>,<AccBankName>,<OrderDesc1>,<OrderDesc2>,(<MandateID>,<DtOfSgntr>,<MdtSeqType>) EDD,Sale,<Amount>,<Currency>,<TransID>,(<RefNr>,)<AccOwner>,<IBAN>,<BIC>,<AccBankName>,<OrderDesc1>,<OrderDesc2>,(<MandateID>,<DtOfSgntr>,<MdtSeqType>) EDD,Capture,<Amount>,<Currency>,<TransID>,(<RefNr>,)<PayID>,(<MandateID>,<DtOfSgntr>,<MdtSeqType>) EDD,Credit,<Amount>,<Currency>,<TransID>,(<RefNr>,)<PayID> EDD,CreditEx,<Amount>,<Currency>,<TransID>,(<RefNr>,)<AccOwner>,<IBAN>,<BIC>,<AccBankName>,<OrderDesc1>,<OrderDesc2> EDD,Reverse,<Amount>,<Currency>,<TransID>,(<RefNr>,)<PayID> FOOT,<CountRecords>,<SumAmount>
Example for Master MID function:
HEAD,[Master]MerchantID,Date,2.x Type,Action,[Slave]MID,Amount,Currency,TransID,Data (depends on Action) FOOT,CountRecords,SumAmount
The following table describes the individual fields and values used within the data set (record) in the batch file:
Description of fields within the record for Batch files
