## Overview

This is a standalone ASP.NET Core API that gates rider–driver communications by trip state, provisions Twilio chat and masked-call sessions, issues client tokens, and records webhook events for history, live status, and recordings. The main workflow runs from trip initialization through client communication and webhook persistence, then closes sessions when a trip ends. The README documents the Trips API behavior; its controller and other unsampled implementation details are represented only where documented, with uncertain links omitted.

Main entry points: [`Data/AppDbContext.cs`](https://github.com/mrehanmehdi/twiliocommmodule/blob/main/Data/AppDbContext.cs) (EF data context), [`Controllers/WebhooksController.cs`](https://github.com/mrehanmehdi/twiliocommmodule/blob/main/Controllers/WebhooksController.cs) (Webhook handlers), [`Controllers/CommunicationsController.cs`](https://github.com/mrehanmehdi/twiliocommmodule/blob/main/Controllers/CommunicationsController.cs) (Communication API), [`Controllers/TripsController.cs`](https://github.com/mrehanmehdi/twiliocommmodule/blob/main/Controllers/TripsController.cs) (Trip lifecycle API)
