Profile

I’ve been tinkering on a side project: a mock PSP (Payment Service Provider) API.It’s meant for developers who want to:- test payment workflows without touching Stripe/Adyen/etc. - quickly simulate authorise / decline / capture states - practice handling webhook events in their appsNo signup needed — you can grab an API key in the console and start calling endpoints. Free tier: 100 requests/day.Live console: https://paylab-ui.vercel.app/ Docs: https://paylab-ui.vercel.app/dashboard/docsRight now MVP supports:- POST /payment-intents - POST /payment-intents/:id/payments (supported payment statuses: initiated, authorising, authorised, declined, capturing, expired, captured, capture_failed) - GE
