CXPI is firmware from Verifone for the Ux series of devices. The Ux series supported by triPOS consists of the Ux300 controller, the Ux100 PIN pad, and the Ux400 contactless reader. Both the Ux100 and Ux400 are add-ons to the Ux300, which runs CXPI.
NOTE: Support for Verifone Vx805 and Vx690 were discontinued in v5.21 as performance degraded and/or could not be guaranteed. In version 6.0.0, Verifone Vx devices cannot be installed.
GET /api/v1/input endpoint are only available on CXPI devices. See Input Endpoint Documentation for a list of prompts supported for each device.
