GitHub Webhook Delivery
Route GitHub push events, pull requests, issue updates, and CI workflow notifications to services inside your private network — behind NAT, firewall, or VPN.
The Problem
GitHub sends webhooks to a public URL for push events, pull requests, issues, releases, and workflow runs. When your CI/CD pipeline, deployment automation, or code review tooling runs behind a corporate firewall, GitHub can't reach those services directly without opening inbound access.
Why This Is Hard
GitHub's webhook signature verification (HMAC-SHA256 with your secret) validates that the payload came from GitHub, but the receiving endpoint must still be publicly reachable. Exposing a CI trigger endpoint to the internet creates a potential vector. Self-hosted runners partially solve the build issue but don't address receiving webhook events into private services for automation, notification, or audit.
How Zen Mesh Helps
Zen Mesh provides a GitHub-ready webhook endpoint that validates GitHub's HMAC-SHA256 signature at ingress, then delivers the event through an outbound-only tunnel into your private network. Your deployment automation and CI infrastructure stay behind your firewall. No public endpoints inside your perimeter.
GitHub Template Pack
The GitHub template includes pre-configured defaults for endpoint setup, HMAC verification parameters, event type mapping (push, pull_request, issues, workflow_run, etc.), and operational visibility.
Runtime Path
Select the GitHub template from the Zen Mesh Registry.
Apply GitHub defaults: endpoint URL, HMAC verification, event type mapping.
Define which GitHub events route to which internal service — pushes, PRs, releases, etc.
Bind the GitHub endpoint, blueprint, and private target into a delivery flow.
Point delivery at your internal CI trigger service or deployment automation.
Security & Evidence
GitHub HMAC-SHA256 signatures validated at ingress. Delivery uses mTLS + HMAC on the data plane. Tamper-evident delivery receipts with hash-chain integrity. See Security for scope and maturity.
Current Status
GitHub templates are available as part of the Provider Template Pack (V1). Signature verification for supported provider templates is validated in local/sandbox. Free Forever and Pro Early Bird tiers include GitHub support.
