Strava Webhook → Vercel Deploy

A Cloudflare Worker that listens for new Strava activities and triggers a Vercel deployment.

How it works

You log a new activity on Strava
Strava sends a POST to this worker
Worker triggers your Vercel deploy hook
Your site rebuilds with fresh Strava data

Setup

Prerequisites

Cloudflare account (free tier works)
Strava API application (create one here)
Vercel deploy hook URL

1. Deploy the worker

CLOUDFLARE_API_TOKEN=your_token npx wrangler deploy

2. Set secrets

CLOUDFLARE_API_TOKEN=your_token npx wrangler secret put STRAVA_VERIFY_TOKEN
CLOUDFLARE_API_TOKEN=your_token npx wrangler secret put VERCEL_DEPLOY_HOOK

Secret	Description
`STRAVA_VERIFY_TOKEN`	Any string you choose for webhook validation
`VERCEL_DEPLOY_HOOK`	Your Vercel deploy hook URL (Settings → Git → Deploy Hooks)

3. Register Strava webhook

curl -X POST https://www.strava.com/api/v3/push_subscriptions \
  -F client_id=YOUR_CLIENT_ID \
  -F client_secret=YOUR_CLIENT_SECRET \
  -F callback_url=https://your-worker.workers.dev \
  -F verify_token=YOUR_STRAVA_VERIFY_TOKEN

4. Verify

Check your subscription:

curl -G https://www.strava.com/api/v3/push_subscriptions \
  -d client_id=YOUR_CLIENT_ID \
  -d client_secret=YOUR_CLIENT_SECRET

Delete your subscription:

curl -X DELETE "https://www.strava.com/api/v3/push_subscriptions/SUBSCRIPTION_ID?client_id=YOUR_CLIENT_ID&client_secret=YOUR_CLIENT_SECRET"

Notes

Only activity + create events trigger a deploy — updates and deletes are ignored
Strava allows one webhook subscription per API application
The worker responds to Strava's validation GET and event POST requests
