#### Using Dynamic Merchant Descriptor

You can submit a merchant descriptor and a telephone number for customer support with each capture or credit request. The descriptor and telephone number will appear on the cardholder's statement.

Note: You must first pre-register the merchant descriptor information with your bank.

The merchant descriptor is accepted by Paymentech and FDMS South payment processors (the entity your merchant bank uses to process all credit card transactions).

Configure the CyberSource basics as described earlier in this Guide.

To use the CyberSource dynamic merchant descriptor:

1. Click the Edit button on the plug-in screen.
2. Mark the Enable dynamic merchant descriptor checkbox.
3. Type the merchant descriptor in the Merchant descriptor field. Valid formats for the merchant descriptor are the following:

   <12-character merchant name>*<9-character product description>

   <7-character merchant name>*<14-character product description>

   <3-character merchant name>*<18-character product description>

   Note: Do not use more than one consecutive space. Extra spaces will be removed. For Paymentech, question marks will be replaced with spaces. You can leave the default merchant descriptor in this field (WEB%domain%) - in this case your customer will get the service type (WEB) and his (or her) actual domain name registered at your HSPstore.

4. Specify the merchant contact information (for example, a phone number) that appears on the cardholder's statement in the Merchant phone number field. Accepted by Paymentech. Valid formats are the following:

   ACCCCCCCCCCCC

   NNN-NNN-NNNN

   NNN-NNN-NUUU

   NNN-NNN-UUUU

   NNN-UUUUUUU

   where:

   N: Numeric

   A: Alpha

   C: Character (Alpha or Blank)

   U: Alphanumeric (Alpha or Numeric)

   Note: Do not use more than one consecutive space. Extra spaces will be removed. Question marks will be replaced with spaces.

5. Click the Update button.
