Webhooks guide

Inspect GitHub webhook deliveries without a local server

GitHub sends a ping after a repository webhook is created. A capture-enabled PNTR hostname lets you inspect that delivery and later redeliver events without keeping a tunnel process online.

Create the GitHub endpoint

Payload URL

https://yourname.pntr.dev/github

Setup

  1. 1

    Create a capture endpoint

    Create a PNTR subdomain with the webhook flow. Copy a URL such as https://yourname.pntr.dev/github.

  2. 2

    Create the repository webhook

    In the repository settings, open Webhooks, add a webhook, paste the PNTR URL as the Payload URL, and choose application/json.

  3. 3

    Select only useful events

    Start with the event types your application consumes. GitHub sends a ping immediately after the webhook is created.

  4. 4

    Inspect headers and body

    Open the PNTR request log. Use the GitHub event and delivery headers to identify the request, then inspect the JSON payload.

  5. 5

    Redeliver while debugging

    GitHub keeps a delivery history and supports redelivery. Use it to repeat the same payload after changing your parser or expected fields.

Before you ship

Use a high-entropy webhook secret for production handlers and verify GitHub's signature. PNTR helps you inspect the request but does not replace signature validation in your application.
