Access Point Model

Felcy acts as an Access Point between your application and the FIRS e-invoicing ecosystem. Your integration talks to Felcy, while Felcy handles the upstream FIRS communication.

How it works

Your Application

Sends requests to Felcy using your Felcy-issued credentials

Felcy Access Point

Validates, logs, secures, and forwards supported requests

FIRS System

Processes validated invoice operations through the Access Point channel

Benefits

  • Simplified integration: a cleaner, more stable interface for your application
  • Security boundary: Felcy isolates external consumers from upstream complexity
  • Operational visibility: invoice activity, sync, and status tracking can be surfaced locally
  • Portal + API split: browser users and server integrations can use different auth models
