Developer APIs
Finmatrix APIs are built for teams that ship. Idempotent writes, signed webhooks, predictable errors, and documentation that does not leave you guessing at edge cases.
APIs that behave the same in docs, sandbox, and production.
REST + webhooks
Create payments and payouts via REST; receive authoritative status via signed webhooks.
Sandbox parity
Test success, failure, and pending paths with simulated bank responses before go-live.
Idempotency keys
Safe retries for network blips without double-charging or double-paying customers.
Role-based API access
Separate keys for staging and production with scoped permissions for your team.
