Attachment Code

A code that indicates the type of file being built. Possible values:

• SA - STANDALONE
• IV - IVR DATA CAPTURE MERCH
• IT - IVR AUTH ONLY MERCH

For DialPay file builds:

• A merchant only needs one terminal configured as IT or IV; any other terminals the merchant has can be configured as SA.
• A merchant cannot have a mix of IT and IV configured terminals.
• Any terminal type can be configured with the IT option.
• The IV Attachment Code should not be applied to any Class A, Class B+. or Class B terminal that uses authentication; it can cause issues with the dial transaction process. The merchant would need to configure a separate IV DialPay terminal.
