The HID® Approve™ Software Development Kit (SDK) is a key component of the HID Global's push-based validation solution whereby logon requests and actions (such as money transfers) can be digitally signed using cryptographic keys stored on a customer’s mobile device.

The HID Approve SDK communicates with the HID authentication platform the ActivID Authentication Server (AS), ActivID Appliance or the HID Authentication Service (cloud platform) - for provisioning and signing. It is hosted on the mobile device and embedded into the customer’s mobile application.

It is recommended that you review the Getting Started to understand the SDK's concepts and usage.
