This section provides API reference for CellPoint Digital's Velocity API. This page provides overview information for all operations, and subpages give sample code and parameter descriptions for each operation. For information on how to integrate Velocity API, see Getting Started, API Quick Start, and our API integration guide.

Specifications

CellPoint's API is XML based*, and it uses standard HTTP response codes and authentication:

* Exceptions: Two API operations do not use text/xml format: Pay By Link (PBL) and Deactivate PBL. For more information, see each operation's API reference.

Special Characters

Please note:

• The following special characters can be sent within Velocity API calls: &, $, #, -, %, _, *, (), {}, [], @, and !.
• Characters outside of this range will impact the init token and cause the call to fail.

Fraud Detection

When a transaction is marked as fraud, CellPoint Digital treats similar transactions in the same manner regardless of the party that marked it as fraud.

For example, if you choose to disable a card payment method after one failed attempt or one fraud transaction, and a specific card transaction is marked as fraud by any system (a PSP, an acquirer, or a fraud system provider), then CellPoint Digital will disable the credit/debit card FOP.
