Maintenance-free proxy API for Stripe & Plaid webhooks and calls
Solo developers building personal finance apps face nightmare Stripe and Plaid integrations with constant API changes and fees devouring slim margins.
PayProxy acts as a unified API gateway: devs swap endpoints to proxy.stripe-plaid.com, handling all auth, retries, and normalizations. It absorbs API changes centrally, sending normalized webhooks and data to your app. Fees are passed-through transparently, preserving your margins without dev overhead.
