Merchant Descriptor Logic Some of the logic described in this section might not apply to your implementation depending on which parts of the merchant descriptor functionality are enabled in your CyberSource account. The logic described in this section applies to the invoiceHeader_merchantDescriptor and invoiceHeader_merchantDescriptorContact fields. It does not apply to the TAA fields. For authorizations, CyberSource provides merchant descriptor information to Chase Paymentech Solutions only when you include merchant descriptor information in the authorization request. For captures, CyberSource provides merchant descriptor information to Chase Paymentech Solutions when you provide merchant descriptor information in the capture request, authorization request, or your CyberSource account. When you do not include the merchant descriptor values in a capture request, CyberSource uses the values from the authorization request. If you did not include the merchant descriptor values in the authorization request, CyberSource uses the corresponding values from your CyberSource account. For follow-on credits, CyberSource provides merchant descriptor information to Chase Paymentech Solutions when you provide merchant descriptor information in the credit request, capture request, authorization request, or your CyberSource account. When you do not include the merchant descriptor values in a follow-on credit request, CyberSource uses the values from the capture request. If you did not include the merchant descriptor values in the capture request, CyberSource uses the values from the authorization request. If you did not include the merchant descriptor values in the authorization request, CyberSource uses the corresponding values from your CyberSource account. For stand-alone credits, CyberSource provides merchant descriptor information to Chase Paymentech Solutions when you provide merchant descriptor information in the credit request or your CyberSource account. When you do not include the merchant descriptor values in a stand-alone credit request, CyberSource uses the corresponding values from your CyberSource account.
