Recent Changes

Nov 27th, 2006:
Several Security Enhancements
Permit the use of only the follow characters: A-Z a-z 0-9 -_./@+, :
Added the ability to do real-time notification of successful transactions.

Overview of Department Storefront

Each department will use their own web server for the initial part of the transaction. They will create and maintain their own web pages which will lead to a "checkout" page. The "checkout" page will contain the names of all items ordered, qty, unit cost, total order cost, etc. Each department will be responsible for calculating sales tax, shipping charges, or any other additional charges which may apply.

The department's "checkout" page will link to a "credit card collection page", which will be a universal web page that ACIS will create and maintain. Limited customization of the credit card collection & response page is permitted by using a departmental header and/or footer file. The "credit card collection page" will ask the customer for their credit card number, expiration date, etc. All customers of all departments will be directed to the same page, in order to enter credit card information.

After the user submits the credit card information the "credit card response page" will be displayed. The credit card response page will contain a standard message indicating that the credit card has been approved or declined.

Department Web Server---->https://acis....---->https://acis...
Checkout page---->Credit Card Collection Page---->Credit Card Response Page

Customizing the Credit Card Collection & Response Pages

A store can make the credit card collection & response pages look more consistant with their storefront by using a header & footer file. A store can choose to use a header, a footer, both, or neither. A store can have multiple header and footer files. However there can not be multiple header or footer files, displayed on one transaction. At most, 1 footer and 1 header file will be displayed during a particular transaction. Let's say that a store had several storefronts. One storefront is for conferences, and another is for donations. It is possible to have a header & footer file for the conference transactions, and two different files for the header & footer files for the donation transactions. (A total of 4 different files.)

The header & footer filenames should contain the store number. For example, store number 10320 could have a header file named header10320riweb.html. The files should contain simple html, no javascript.

In order to setup your store to use header & footer files, the files need be emailed, as attachments to creditcard-info@lists.andrew.cmu.edu. We reserve the right to edit the html files if we deem appropriate before we upload them to the server.

The header and footer filenames are then specified as hidden variables that are sent to the credit card collection page.

Secure web server for collecting credit cards

The department's web server does not have to be a secure web server. (A secure web server has a URL which begins with https:// instead of http:// ) A secure web server is required to enter credit card information. ACIS will provide a secure server for this part of the process.

Using Frames If your department's web site uses frames, and will call the credit card collection page within a frame, then your department's web site must be on a secure server. If you call the credit card collection page from within a frame, and your departmental web page is not on a secure server, the user's browser will not appear to be secure. For example, in this case, the lock that appears at the bottom of the Netscape browser will not be closed. The connection will be secure, but the user's browser will not appear to be connected to a secure server. This is only an issue if the credit card collection page is called from within a frame, that is hosted on a server which is not a secure server.

Department Information for Store Setup

Every department will be assigned a 5 character store number. This store number will need to be included in the information that is included in the "check out page".

We will require the following information for each department


The following department specific information will be displayed on the "cc response page".

Accepting Gifts

Do not use the ecommerce process to accept university gifts. It is extremely important that all ecommerce gifts are processed through the Carnegie Mellon "Make a Gift" web site. A hyper link can be added to your page that will take the donor to the official university on-line gift page. If you have any questions regarding gifts to the university please call the Office of Gift Accounting at 412/268/2027.

How will my transactions get into Oracle Financials?

ACIS will be responsible for posting all credit card transactions into the financial system. This will occur nightly.

What should we do if a customer contacts us?

There will be real time access to detailed credit card transaction information through a secure web site. If a "notify email" address is included on the checkout page, then detailed transaction information will be sent to this address immediately following the response from the credit card processor. If more than 1 person needs to receive the credit card transaction confirmation email, then we recommended setting up an email mailing list for this purpose. Alternatively, an email address that posts to a bbs can be used.

How can I update my department backend database with the credit card information?

ACIS will create a standard comma delimited outload file of all credit card transaction information for each department. This file will include the merchant_ref_no, which you can use to identify the transaction in your database.

Detailed Outload File Information

What needs to be on my "checkout" page?

flex_field3c100Additional optional flex field
flex_field4c100Additional optional flex field
flex_field5c100Additional optional flex field
flex_field6 c100 If a transaction is for a service the storefront is required to provide the beginning and ending dates (Range of Service) for the service. Generic storefronts will use the field named "Range of Service". Regular storefronts are to record the range in flex_field6. The format should be MMMDD - MMMDD (JUN08 - JUL12). In the event a single credit card transaction is for more than one item that meets the above criteria then the range of dates should be enclosed in brackets (format [MMMDD-MMMDD][MMMDD-MMMDD]). The date order should correspond to the Item Detail order. The following are examples of services that require the range of dates be provided:
  • Conferences
  • Educational programs (i.e. executive education)
  • Fees for events and activities
  • Fees for advertising
  • Fees for memberships and dues
header_filec30Optional field to specify which html file to use as a header on the credit card collection & response page.
footer_filec30Optional field to specify which html file to use as a footer on the credit card collection & response page.

itemX_namec50Name of item
itemX_skuc20Product SKU (optional)
itemX_qtyintegerItem quantity
itemX_price_eachfloatPrice PER item
itemX_gl_strc25Oracle Financials GL String

Note

The above variables should be sent as hidden variables with a post request. Additional Note: Due to the prevalance of pop-up blocker software, it is preferred for you to call the credit card collection page within the same window. If you call the credit card collection page in a new window and the user has pop-up blocker software enabled, the customer will never see the credit card collection page.

How does this charge appear on the customer's credit card?

There is only 1 merchant identifier for the university, which greatly reduces costs. So regardless of the storefront which charged the customer, the customer's credit card statement will show the charge as
Carnegie Mellon Univ Pittsburgh PA

How can I get immediate notification of a successful transaction?

The merchant reference number of all successful transactions can be sent real-time to a pre-determined URL that you provide for your store number. This will provide your store with immediate notification for all successful transactions. In order to use this feature, the following criteria is required:

What about sales tax?

If you are going to consider the use of the web for external sales, you certainly do need to be aware of the requirements for collection of sales tax.

How the process will work, though, is fairly straight-forward... for the "generic storefront" process, the sales tax will be manually calculated and added as a separate line, with the credit going to 4031500000000000000000101, which is a university liability balance sheet account to record this activity. Judy Cvejkus files and remits collected sales tax to the State. We're finalizing the actual procedures in terms of how this will be handled through the web application.

If a department has a "regular storefront", this functionality will need to be programmed into the page, such that items will need to be flagged as taxable or non-taxable (e.g., clothing is not taxable), tax will need to be calculated (7%), and then identified to the above-noted GL string for distribution.

Lastly, in terms of identifying taxable/non-taxable, Lisa Luffe (Manager of Financial Reporting & Taxation) can be a resource.

How can I issue a credit to a customer?

The credits are issued through the web search screen. There is a production and test credit card search screen. Enter as little information as possible into the search screen, that will identify the transaction. Simply putting in part of their last name is usually sufficient. A common mistake is to enter all of the information that is available on the search page. This often causes no records to be returned.

The search page will return a summary screen containing the Date, Name, Merchant Ref no, etc. Click the radio button that is in front of the transaction to be credited. Press the submit button at the bottom. This will display more detailed information about that transaction. Scroll to the bottom of that page. A button labelled "Issue a Credit Now" will be displayed. Press this and a screen will appear that will allow the amount to be credited to be entered.

Why is the 'Issue a Credit' screen asking for the credit card expiration?

There are rare occasions when the 'Issue a Credit' screen will include fields for the credit card month and year expiration. When these fields appear on that screen, values for the expiration month and year must be provided. This occurs when a credit card needs to be credited, after the credit card expiration has passed. Please contact the card holder and obtain the new expiration information. Once that has been entered into those fields, the credit can be issued.

Is it possible to cancel a charge, or a credit?

You can request that a charge or a credit be canceled only on the day that the charge or credit occured. At the end of the day, around midnight, the card processor creates a batch of all transactions from that day. The batch is then processed. Before the batch is created, it is possible to void or cancel transactions.

You can submit your request by emailing creditcard-info@lists.andrew.cmu.edu with the details of the transactions and the reason for the request. Someone from the credit card team will submit the request to the card processor.

What is the difference between a generic storefront and a regular storefront?

The difference between a regular storefront and a generic storefront is who is entering the credit card information.

A generic storefront can only be accessed by pre-designated andrew ids. It is meant to be used, for example, by admin staff who get credit card orders over the phone. The generic storefront is a generic web page, and does not require the store to create their own website.

A regular storefront is meant to be a self-serve application where the customer chooses their products and services and then completes the transaction themselves. In order to use the regular storefront, the department needs to create their own website, and host it on their own server.

One department can have both a generic & regular storefront with the same store number. This would allow the department, for example, to have customers signup and pay for a conference themselves through the website (using the regular storefront). The department can also process credit card payments from faxed payment forms (using the generic storefront).

Overview of Generic Storefront

The generic storefront is for use by authorized Carnegie Mellon University employees only. Access to this storefront will require an Andrew username and password. Generic storefront users will be setup by the Financial Services Group and will be associated with an store.

The purpose of the generic storefront is to replace traditional credit card terminals when most or all of the transactions are Card Not Present. For example, if a customer provides credit card information over the phone, the user can process the payment from their desktop. This provides immediate feedback to the customer, and eliminates the need to put confidential credit card information on paper.

The user logs into the website and brings up the generic storefront screen. In the example shown, the store has setup the generic storefront default values for


The screen already has defaulted values for Settle Now of Yes. The data entry required is now quite minimal. The user need only verify the default values, enter a price and choose a GL string from the select list. The next screen is the standard credit card collection page.

The transactions from the generic storefront are handled in the same way as transactions from the department storefronts.

How does one setup a generic storefront ?

How long does it take to setup a generic storefront?

Once all of the data is submitted, setup will take less than 2 business days.

Can we use both a generic and department storefront?

Yes. It is possible to use both the generic storefront and a department storefront with the same store number.

How much is this going to cost?

Total Fees

For Visa & Mastercard
27 cents per transaction + roughly 2.0%

For American Express
27 cents per transaction + roughly 2.9%

Breakdown of fees

1) Bank Intercharge Rate This is where Visa/MasterCard/American Express charges the merchant to accept the card as a form of payment. These fees are variable based on a number of circumstances, but roughly will come in at around 1.9-2.1% for Visa/MasterCard, while it is roughly 2.9% for American Express In addition, we pay $0.10/transaction.

2) Paymentech This is our processor, who moves the funds between the cardholders bank and our bank. We pay a fixed .2663% (.002663) of the transaction amount.

3) CyberSource This is our third-party web source who provides us with the ability to process these credit card payments over the web. We allocate the university cost of this service currently at $0.17/transaction.
