Built for Shopify flash sales & drops

Never drop an order during a drop.

Restocks, influencer shoutouts, and scalper bots send traffic to your backend in bursts no normal integration is built for. Data Dam sits in front of it, absorbs the spike, and drains it in at a rate your systems can actually handle — so every order still lands.

No code to write or maintain

Sign up, paste the URL your backend already listens on, and swap it for a Data Dam proxy URL in Shopify’s webhook settings. That’s the whole integration.

1. Paste your URL

Tell us where webhooks currently go — no SDK, no deploy.

2. Get a proxy URL

A dedicated Data Dam URL, ready in seconds, with its own signing secret.

3. Update Shopify

Paste it into your webhook settings. Traffic now flows through Data Dam first.

A Cloudflare Worker can buffer requests. It can’t survive a crash mid-drop.

The “accept fast, forward slow” idea is simple. Getting it right under the exact burst shapes a flash sale produces — without losing an order — is not.

A quick Worker/Queue

  • No write-ahead log — a crash mid-burst can silently drop orders
  • No dead-letter recovery when your backend rejects a batch
  • You write and maintain the integration code yourself

Data Dam

  • Write-ahead log + crash recovery on every partition
  • Deterministic load-shedding and staggered delivery so your backend is never hammered
  • Paste a URL — zero integration code

Ready before your next drop

Takes about a minute. No credit card to get your proxy URL.
