For Individual Developers

Stripe Webhooks on a Freelance Project

When Maria, a freelance full-stack developer, was building a subscription dashboard for a client, she used HookCheck to verify that Stripe's invoice.payment_succeeded payloads matched her database schema. She caught a mismatched currency field on her third test payout — before the client's first real customer checked out.

Shopify Order Notifications for a Side Project

Tariq, a junior developer building an inventory tracker, pointed Shopify's webhook endpoint to his HookCheck URL. Within 20 minutes of creating a test order, he saw that Shopify was sending orders/create twice per checkout. He adjusted his deduplication logic and avoided a production incident he couldn't have reproduced locally.

GitHub Webhooks Before Deploying to Vercel

Before pushing his CI pipeline to production, solo developer Jonas used HookCheck to inspect the raw JSON from GitHub's push events. He noticed that ref came through as refs/heads/main instead of just main — a one-line fix that would have broken his branch-filtering logic for every contributor.

Twilio SMS Callbacks During a Hackathon

During the Amsterdam Tech Sprint, team lead Anouk hooked her Twilio number to a HookCheck endpoint to validate incoming Body and From parameters in real time. Her team iterated on their SMS parser between messages instead of redeploying after every guess.

Laravel Echo WebSockets Without ngrok

Freelancer Samir replaced his ngrok tunnel with a HookCheck endpoint while debugging Laravel's webhook-driven notifications. He got a persistent HTTPS URL, viewed request headers with signature verification, and shared the live log with his client during a demo call.

Webflow-to-Zapier Payload Inspection

When designer-turned-developer Leah needed to confirm that Webflow's form submission webhooks were passing through all custom fields, she routed them through HookCheck first. She discovered that two dropdown fields were being serialized as arrays instead of strings — a silent data loss she fixed before connecting Zapier.

"I was spinning up ngrok every time I needed to test a webhook for a freelance client. HookCheck gave me a permanent URL I could drop into Stripe, and the request history let me replay payloads while I fixed my handler. Saved me at least four hours over two projects."

Maria Veldhuis — Freelance Full-Stack Developer, Rotterdam

"As a junior dev, I didn't know how to expose my localhost to the internet. HookCheck removed that entire barrier. I pasted my endpoint into Shopify, triggered a test order, and saw exactly what was coming through. It felt like magic."

Tariq El Amrani — Junior Developer, Utrecht

"I built a solo SaaS that processes GitHub webhooks. I used HookCheck during development to catch edge cases — like when a repository gets renamed mid-push. By the time I deployed to production, I'd already seen every weird payload GitHub could throw at me."
