Sign up for and set up an FDMS-compatible merchant account

Yahoo! Store uses First Data Merchant Services (FDMS) as the payment gateway to process transactions from your store in conjunction with your merchant account. It is only possible to setup a Yahoo! Store for online processing with a merchant account that uses First Data Merchant Services (FDMS) as described below.

If you need to sign up for a merchant account and you do not wish to use First Data™, you can explore other FDMS-compatible merchant account providers. Once you have been accepted for a merchant account, use the instructions below to set up your merchant account in your store.

If you have an existing merchant account, your first step is to determine if your merchant account is compatible with the FDMS Nashville Platform. Contact your merchant account provider to determine if this is the case. If your merchant account is not compatible with FDMS, you can still process credit cards orders offline.

To set up an existing merchant account:

1. Ask your merchant account provider for a new MID/TID pair for your Yahoo! Store. You should ask them to use the following information in the setup:
   • Product Name: Yahoo! Store FDMS (g/w)
   • Product ID:819000
   • Vendor Name: Yahoo!
   • Vendor ID:190
   (Once you have this information, you will need to log in to your store to set up online processing.)
2. From Store Manager, click the "Pay Methods" link under the "Order Settings" column. (You may be prompted to enter your security key to proceed).
3. Select the option buttons for the card types that will be available for your customers to choose when they go through the checkout process. These do not necessarily have to be the same as the card types that your merchant account provider accepts if you plan to process some cards individually offline. Once you have finished selecting the cards you wish to make available, click the "Update" button. (The page refreshes showing the selections for each card type.)
4. Click the "Set up processing through FDMS" link under Option # 2 (see B figure 1).
5. Enter your merchant account information supplied to you by your merchant account provider into the fields and select the supported credit cards (see A-E Figure 2):

1. Name of Bank—enter the name of your merchant bank
2. Merchant Number—enter your merchant account number. If you have multiple accounts you need only enter the number for one.
3. MID—enter your Merchant Identification number; valid MID and TID numbers on this platform are usually 7 digits long each (not counting any leading zeroes). MID is not the same as your merchant account number.
4. TID—enter your Terminal Identification number
5. Cards—select the credit cards for which your account is set up.

Note: Check that your MID and TID are accurate before you finalize the setup process and select only the cards that your account is capable of processing.

1. Click the "Setup" button. (You will be taken to the Payment methods page.) Your set up is complete.

You will be emailed instructions on how to process your orders within your Yahoo! Store. Additionally, you may review our order processing help pages.

There is no additional charge for using your own merchant transaction service provider.
