lingxi-webhook-dispatcher

An intelligent webhook routing system with automatic GitHub API fallback when standard push fails.

Problem It Solves

Git push can fail due to:

• Port 443 blocked by firewall/network
• DNS resolution issues
• SSL certificate problems
• Rate limiting on git protocol

This skill provides a robust fallback: when git push fails, automatically route to GitHub Contents API (PUT /repos/{owner}/{repo}/contents/{path}) to upload files directly.

Architecture

git push → [fails] → Webhook Dispatcher
  → GitHub Contents API (fallback upload)
  → Retry logic (exponential backoff)
  → Delivery receipt (JSON log)
  → Alert notification (if still failing)

Usage

Trigger: Automatic on git push failure

When: git push fails in any workflow
Action: Dispatcher intercepts → GitHub API fallback → Upload files
Output: Delivery receipt at ~/webhook-dispatch/logs/YYYY-MM-DD.json

Manual Dispatch

Trigger: "Dispatch files to GitHub via API"
Action: Uploads specified files to GitHub using Contents API

Fan-out Dispatch

Trigger: "Push this update to repos: [repo1, repo2, repo3]"
Action: Parallel upload to all specified repos
Output: Summary report of success/failure per repo

Configuration

{
  "github_token": "ghp_xxx",
  "default_owner": "nima54851",
  "retry_attempts": 3,
  "retry_backoff_ms": 1000,
  "log_path": "~/webhook-dispatch/logs/",
  "alert_webhook": "https://your-alert-channel.com/webhook"
}

GitHub Contents API Upload Flow

# 1. Get current file SHA (if exists)
gh api repos/{owner}/{repo}/contents/{path} --jq '.sha'

# 2. Upload with SHA for update (or no SHA for new files)
gh api -X PUT repos/{owner}/{repo}/contents/{path} \
  -f message="Automated dispatch: {timestamp}" \
  -f content=$(base64 -w 0 file.txt) \
  -f sha={sha}

Retry Logic

Installation

clawhub install lingxi-webhook-dispatcher

Integration with GitHub Actions

Add to your workflow as a fallback step:

- name: GitHub API Fallback Dispatch
  if: failure()
  run: |
    curl -X POST https://your-dispatcher-endpoint.com/dispatch \
      -H "Authorization: Bearer ${{ secrets.DISPATCH_TOKEN }}" \
      -d '{"event": "push_failure", "repo": "${{ github.repository }}"}'

Use Cases

1. CI/CD Pipeline Fallback: When git push fails in CI, use API to push artifacts
2. Automated Reports: Daily/weekly reports uploaded via API instead of git
3. Multi-repo Sync: Push same content to multiple repos simultaneously
4. Offline-to-Online Sync: Store changes locally, sync via API when network is available
