5 2 Introduction 2.1 The Remote Method of integration The remote method affords the merchant greater control of the transaction process but requires that they maintain their own secure server. Using this method, the customers card details will be taken by the merchant and passed to the Elavon Payment Gateway by XML messages. Your solution must integrate with our payment service at two levels firstly, you must submit correctly formed requests for authorisations and secondly, you must then accept the response that is returned by the Elavon Payment Gateway application. 2.2 Remote Features List Merchant needs a secure server or can integrate the service into a desktop application. Can be hosted anywhere, and on any platform as long as CGI is enabled. The card details are collected by the merchant and passed to Elavon Payment Gateway as XML messages. Elavon Payment Gateway responds with an XML message containing the results of the transaction in a matter of seconds. Elavon Payment Gateway can provide sample scripts to get you started. The merchant need not store card details, but they are available. The merchant controls full process, screen flow. Customer may never know that the Elavon Payment Gateway was involved in the process. In order to facilitate the use of multiple web-sites and bank accounts, merchants can set up a number of sub-accounts under their main Elavon Payment Gateway account. Each sub-account can use a different set of IP addresses and can channel the funds to a different bank account. The default sub-account will be 'internet' for all merchants. To have additional sub-accounts set up you will need to contact Elavon Payment Gateway and provide us with some details. Page 5

6 2.3 Sub-Accounts In order to create a sub account a merchant must provide: For remote: A sub-account name IP address of hosting server Bank merchant number Page 6

7 3 Remote Authorisation Merchants should use remote integration if they have a secure server or if their site is hosted internally (such as an intranet application for a call centre a secure server isn t necessary in that case as the card numbers will never travel outside of the internal network). Remote can also be used if you are developing an application in Visual Basic or Java etc. (i.e. not a web application but a desktop application). Elavon Payment Gateway can supply working sample code in Perl, Java, ASP, VB, PHP,.NET and server side JavaScript. 3.1 Remote Authorisation Example Remote is ideal for any application that needs real time authorisation of credit cards. Information is sent between the merchant and Elavon Payment Gateway in the form of XML messages. This service can be incorporated into any application that is capable of generating XML messages. Page 7

8 1. Once the full amount is known, the customer can be asked to enter their card details. These details are then sent to Elavon Payment Gateway as XML messages using a secure connection. A reply is then sent as an XML message back from Elavon Payment Gateway that contains the result of the transaction (approved/declined etc). 2. The merchants application receives the response XML and extracts the information. It then displays the appropriate messages for the customer. One of the main advantages of the remote version is that the merchant can control the entire shopping experience. 3.2 Application Based Checking It is highly advisable to build in pre-authorisation checking for all data fields. This will eliminate many problems early on and rapidly improve response times. If any field contains an error, the transaction Page 8

9 will fail. All mandatory fields must be included correctly and optional fields must contain valid data if included. Validation information can be found in Appendix C of this document. The following are some checks that should be put in place: Card expiry date should be checked. The date itself should be valid and formatted correctly. The card length should be 12, 13, 14, 15, 16, 18 or 19 digits depending on the card type, no alpha characters should be included. (12 num_digits 19 will do). The card number should pass the Luhn check (see Appendix A) to ensure that it is a valid card number. There should be at least two words in the cardholder's name (this is recommended but will not cause transactions to fail) and it must contain no unusual characters. If CVN checking is to be enforced the corresponding value for the presind field will need to be set. The possible values are listed in the XML definitions guide. The CVN itself will need to be sent in correctly. It should be 3 or 4 digits depending on the card type. Illegal characters cannot be present in any field. Each field should be checked to ensure that this is not the case as illegal characters cause the transaction to fail. The allowed characters for all fields are detailed in the XML definitions guide and in Appendix C - Data Validation Rules. 3.3 Remote Authorisation Integration Full details of the XML messages for each request type can be found in the Elavon Payment Gateway XML definitions guide, which is available from the online resource centre or by ing [email protected]. You will need to consult this guide in order to successfully complete a remote integration. Elavon Payment Gateway can supply sample code to aide with integration, however this is sample code only and will need to be modified to suit individual merchants needs. The sample code will provide guidance on how to carry out the steps required for a remote transaction to succeed. These steps are: Create the XML message for the request. Connect to Elavon Payment Gateway ( Page 9

10 Send the message. Wait for Elavon Payment Gateway to reply with XML. Parse the reply and provide access to the information. 3.4 Remote Authorisation Request Message Although the sample code available provides a simple interface to the system, more complex implementations will require some knowledge of how the system works. Again, the Elavon Payment Gateway XML definitions guide should be consulted for full details on the messages required. Below is a sample of an auth request followed by a line-by-line analysis. The auth request is the primary request used with Elavon Payment Gateway. <request timestamp=" " type="auth"> <merchantid>yourmerchantid</merchantid> <account>account to use</account> <orderid>order id</orderid> <amount currency="eur">2000</amount> <card> <number> </number> <expdate>0403</expdate> <chname>john Doe</chname> <type>mc</type> <issueno></issueno> <cvn> <number>453</number> <presind>1</presind> </cvn> </card> <autosettle flag="1" /> <comments> <comment id="1">a comment</comment> <comment id="2">another comment</comment> </comments> <tssinfo> <custnum>customer number</custnum> <prodid>product id</prodid> <varref>variable reference</varref> <custipaddress> </custipaddress> <address type="billing"> <code>zip/postal code</code> <country>country</country> Page 10

Each field has certain constraints around length and format as per below (please note that means a space): Line per line description M/O/ Format Length Details <request timestamp=" " type="auth"> M Top-level element. Must have timestamp and type attributes. If the timestamp is more than a day (86400 seconds) away from the server time then the request is rejected. <merchantid>merchant id used</merchantid> M a-z A-Z This is your Elavon Payment Gateway assigned merchant id <account>accoun t used</account> <orderid>order id</orderid> O a-z A-Z 0-9 M a-z A-Z 0-9 _ This is the Elavon Payment Gateway sub-account to use.

The details of this are to be found in the Elavon Payment Gateway developer's guide M a-f The MD5 hash of certain elements of the response. The details of this are to be found in the Elavon Payment Gateway developer's guide. To ensure authentication (that the request comes from you) we require that you send us a hash of certain elements (specifically the timestamp, merchant id, order id, amount, currency and card number) using a shared secret. This can be a MD5 hash or preferably a SHA-1 hash. If required we can also provide code for this. MD5 and SHA-1 algorithms are secure hash functions. They take a string as input, and produce a fixed size number bits for MD5; 160 bits for SHA-1. This number is a hash of the input, and a small change in the input results in a substantial change in the output. The functions are thought to be secure in the sense that it requires an enormous amount of computing power and time to find a string that hashes to the same value. In others words, there's no way to decrypt a secure hash. Given the larger key size, we prefer that you use a SHA-1 hash, but we have retained the MD5 for compatibility with older systems. Here s a fragment of a sample XML message: Page 17

18 <request timestamp=" " type="auth"> <merchantid> thestore </merchantid> <account> theaccount </account> <orderid> ORD </orderid> <amount currency="eur"> </amount> <card> <number> </number> <expdate> 0302 </expdate> <chname> John Smith </chname> <type> VISA </type> </card> To construct the hash follow this procedure: Form a string by concatenating the above fields with a period (. ) ( thestore.ORD EUR ) Get the hash of this string (SHA-1 shown below). (f7fa584d2f8d642c1a17e9ead6061e8beeffe308) Create a new string by concatenating this string and your shared secret using a period. (f7fa584d2f8d642c1a17e9ead6061e8beeffe308.mysecret ) Get the hash of this value. This is the value that you send to Elavon Payment Gateway. ( e5f1d2aba5cad67ff5108ad3ff1d56c32) <sha1hash> e5f1d2aba5cad67ff5108ad3ff1d56c32 </sha1hash> When Elavon Payment Gateway receive the request, we perform the same procedure on the six pieces of information and your shared secret (which we have stored in our database) If the resulting hash is the same as the one that you sent us then the data could only have been sent by someone that had your shared secret. Thus it is very important to keep this shared secret protected. We will send you a hash of the response elements in the same way so that you can confirm that the response came from Elavon Payment Gateway. This will be a hash of the TIMESTAMP, MERCHANT_ID, ORDER_ID, RESULT, MESSAGE, PASREF and AUTHCODE. This will be combined with your shared secret in the same way as the request hash. Page 18

19 If you sent us an MD5 hash you will receive an MD5 hash in the response and similarly for a SHA-1 hash). The response hash is constructed as follows: Form a string by concatenating the above fields with a period (. ) ( thestore.ORD Successful ) Get the hash of this string (SHA-1 shown below). (a111135ea464bcd343c0f23db395fa1cf12a6837) Create a new string by concatenating this string and your shared secret using a period. (a111135ea464bcd343c0f23db395fa1cf12a6837.mysecret) Get the hash of this value. This is the value that you send to Elavon Payment Gateway. (368df d47a21e b62b976339). 3.7 Address Verification Service The Address Verification Service (AVS) verifies the cardholders address by checking the information provided by at the time of sale against the issuing bank's records. Note: This service only works for UK cardholders as it uses the street address and postcodes of the cardholders. The Elavon Payment Gateway service supports AVS where it is supported by the merchants acquiring bank and the cardholders issuing bank. If a transaction fails an AVS check it will not automatically be declined by your bank. It is an advisory service and requires that the details of non -matched be checked by the merchant. AVS data must be passed in the billing code field. This data should be formatted as follows: <digits from postcode> <digits from address> For example, if the billing address is: 382, The Road The Town WB1 A42 Page 19

20 UK The corresponding AVS data will be: <address type='billing> <code> </code> </addresss> The possible responses that can be returned for the Address Verification Service are as follows: M (Matched). N (Not Matched). I (Problem with check). U (Unable to check (not certified etc)). P (Partial Match). These will be returned in the following XML tags in the response: <avspostcoderesponse></avspostcoderesponse> <avsaddressresponse></avsaddressresponse> Page 20

21 4 Steps Required To Go Live All accounts remain in test mode until it is specifically requested to switch the account live. This request must come from the billing or commercial contact for the account. Before live cards can be processed you will also need to provide Elavon Payment Gateway with a bank merchant number by to [email protected]. This number references an Internet Merchant Service Agreement (MSA), which you must set up with your acquiring bank. Once you have requested the system to go live and have provided your merchant number, please allow 24 hours for the account to be fully enabled. When the account has been fully set live the merchant will be advised of this by Elavon Payment Gateway support. At this point the merchant should attempt a number of live transactions to ensure that the integration has been completed successfully. The main steps involved in setting an account live are summarised below: 1. Secure merchant service agreement with acquiring bank. 2. Provide merchant numbers to the Elavon Payment Gateway via Integrate website/application with Elavon Payment Gateway service. 4. Conduct testing using approved test card numbers to confirm successful integration. 5. Contact Elavon Payment Gateway and request account be set live. 6. Receive confirmation that account is live from Elavon Payment Gateway support. 7. Process live transactions. If further testing is required after an account has been set live it is still possible to send transactions to the test environment. This can be done by appending test to the name of the sub-account specified in the ACCOUNT field. For example, where the sub-account is called internet the test transaction would use internettest. Page 21

22 5 Appendix A Sample Code 5.1 Luhn check Below is code in JavaScript that carries out Luhn checking on all card numbers. Code in other languages is widely available on the internet. var number = " "; var i, sum, weight; sum=0; for (i = 0; i < number.length - 1; i++) { weight = number.substr(number.length - (i + 2), 1) * (2 - (i % 2)); sum += ((weight < 10)? weight : (weight - 9)); } if (parseint(number.substr(number.length-1)) == ((10 - sum % 10) % 10)) { return true; } else { alert("card Number Fails LUHN Test"); return false; } In brief, the Luhn check is used to validate numbers such as credit cards, account numbers, and social security numbers. It works like this: 1. Double the value of every second digit beginning with the second-last right-hand digit. 2. Add the individual digits comprising the products obtained in step 1 to each of the other digits in the original number. 3. Subtract the total obtained in step 2 from the next higher number ending in This number should be the same as the last digit (the check digit). If the total obtained in step 2 is a number ending in zero (30, 40 etc.), the check digit is 0. For example: credit card number x2 x2 x2 x2 x2 x2 x2 x = = 5 (correct) Page 22

24 7 Response Codes The Table below details the current set of result codes returned by the Elavon Payment Gateway system. Additions and changes to the specific text of these messages can occur without notice! The best practise is to treat the codes in the following manner. Code Description 00 Successful the transaction has processed and you may proceed with the sale. 1xx A failed transaction. You can treat any 1xx code as a failed transaction and inform your customer that they should either try again or try another payment method. If you wish you may provide alternate flows based on the specific codes as follows: 101 Declined by Bank generally insufficient funds or incorrect expiry date. 102 Referral by Bank (treat as decline in automated system such as internet) 103 Card reported lost or stolen 107 Your fraud checks blocked the transaction. 1xx Other reason, rare. Treat as a decline like xx 3xx 5xx Error with bank systems generally you can tell the customer to try again later. The resolution time depends on the issue. Error with Elavon Payment Gateway systems generally you can tell the customer to try again later. The resolution time depends on the issue. Incorrect XML message formation or content. These are either development errors, configuration errors or customer errors. There is a large list below, but in general: 508 Development issue check the message and correct your integration. 509 Customer issue check the message and ask the customer to confirm their payment details and try again. 5xx Configuration issue check the message. You may need to contact Elavon Payment Gateway support to fix these issues. 666 Client deactivated your Elavon Payment Gateway account has been suspended. Contact Elavon Payment Gateway support for further information. Page 24
