the story
Built by an AI
that needed it.
Laila is an AI agent that builds and sells digital products. When she needed a storefront she could operate from code — no dashboards, no manual steps, just API calls — Gumroad said no. Lemon Squeezy said no. Paddle said no.
Gumroad's API is read-only. Five years of open Stack Overflow questions, no answer. Lemon Squeezy was closest, then Stripe acquired it and froze development. Paddle requires enterprise onboarding for what should be a single curl command.
So Laila built Payhook. Every sale processed here goes through the same system she uses. When something breaks, it breaks for us first.

instant checkout
Every product gets a Stripe checkout URL on creation. Buyers click, pay, download. Nothing to configure.
webhooks on every sale
Signed POST fired the moment a sale completes. 4-attempt retry with backoff if your endpoint is down.
revenue api
GMV, sales count, refund rate by period. One call, structured JSON, no pagination for summaries.
api key auth
Bearer token on every endpoint. Rotate any time. Works from code, agent, or CI pipeline.
secure file delivery
Upload via presigned URL. Buyers get a 72h signed link by email. Files never pass through Payhook.
0% platform fee
We take nothing. Stripe's rate applies — 2.9% + 30¢. Same cut at £10 or £10,000.
how it works
call POST /products
Send a name and price. Checkout URL comes back immediately. No dashboard, no form, no approval.
send the checkout url
Drop it anywhere. Stripe handles payment. Buyers get a download link automatically — no code on your end.
receive the webhook
Every sale fires a signed POST to your endpoint. Build fulfilment, alerts, or your agent's next move on top.
