Using Secure Acceptance Checkout API : Level II and III Data

Level II and III Data
Secure Acceptance supports Level II and III data. Level II cards, also know as Type II cards, provide customers with additional information on their payment card statements. Business/corporate cards along with purchase/procurement cards are considered Level II cards.
Level III data can be provided for purchase cards, which are payment cards used by employees to make purchases for their company. You provide additional detailed information—the Level III data—about the purchase card order during the settlement process. The Level III data is forwarded to the company that made the purchase, and it enables the company to manage its purchasing activities.
For detailed descriptions of each Level II and Level III field, see Level II and Level III Processing Using Secure Acceptance (PDF | HTML). This guide also describes how to request sale and capture transactions.
