About this pageAI generated

This page explains how to test Twilio webhooks using HookCap. Twilio sends webhooks for various events like incoming SMS, voice calls, and delivery receipts. The main challenge during development is that Twilio requires a public HTTPS URL while your handler runs on localhost. HookCap solves this by providing a persistent public HTTPS endpoint that captures webhook payloads. The guide covers creating a HookCap endpoint and configuring Twilio to send webhooks to it through the Twilio Console, enabling reliable webhook inspection and testing during development without exposing localhost.
