Level III Data

You can provide Level III data for purchase/procurement cards, which are used by businesses for expenses such as supplies and services. These cards are often used as replacements for purchase orders. The Level III data is forwarded to the company that made the purchase. It enables the company to manage its purchasing activities.
Check with your processor to determine whether you need to add Level III processing to your contract or account setup. Support for Level III processing is processor and card specific. See Supported Processors and Card Types: Level III for a list of the supported card types for your processor.
When you are ready to go live with Level III processing, contact Customer Support to have your account configured to process Level III data. If your account is not enabled and you try to send Level III transactions, you will receive an error for invalid data.
IMPORTANT
Unless otherwise specified, Level III transactions must include Level II data.
