PEX Developer Center

PEX is a business expense prepaid card that helps your company control employee spending. You can issue and fund cards, and apply spending controls including restricting spending to specific merchant categories.

The power of the PEX platform is available through a complete set of JSON based APIs and Webhooks which can be used to duplicate every feature available in our admin portal as well as support a few features that aren’t.

The PEX platform can be used to power any proprietary expense management or business payment application and create a seamless payment experience for your users.

Note: You must have a PEX Business Account in order to use the PEX API.
