Overview

This document describes how partners can integrate their systems with Call Me using the **postpaid pay-as-you-go** model.

Billing is calculated per participant-minute.
Call duration is rounded up to the nearest full minute.
Formula: 2 participants in a call for 5 minutes = 10 billed minutes.
Default billing rate is Rp 100 / minute / participant.
API keys and secrets must be kept securely on your partner backend server, never in public clients.
Each partner operates in an isolated namespace. Room codes like `TEAM-01` owned by Partner A and Partner B are isolated and can coexist simultaneously.
