Everything to integrate payments except accepting payments.

Mockpay is a Stripe-clone API for integration testing. Wire your application to a payments platform that behaves like the real one and never moves a cent.

  -u mock_sk_51H8sandbox: \
  -d amount=2000 \
  -d currency=usd

Built for the integration, not the transaction

Stripe-shaped API

payment_intents, customers, payment_methods — the shapes your integration already speaks, served from a sandbox that is always test mode.

Deterministic outcomes

Test cards that decline on purpose. Exercise every failure path before production finds one for you.

Webhooks both ways

Signed outbound events, plus a hosted catcher to inspect what any provider fires at you.
