Typed clients
Generated from the same spec the API serves, so the client cannot drift from the server.
Idempotent by default
Every write takes a key. Retries are safe without you designing for them.
Sandbox that matches
The test environment runs the same code path, including the failures you need to handle.
Product direction
See where the money actually went
Monitor activity in real time, and resolve the question the same day it is asked.
One timeline
Charges, refunds, disputes and payouts on a single ordered view rather than four exports.
Filters that persist
A view you set is a view you can link to, so a question asked once can be asked again.
Exports that reconcile
CSV totals match the dashboard totals, because both read the same ledger.
What you get
Built out of smaller, sturdier blocks
Everything needed to launch and scale, designed for speed, reliability and a developer experience that does not fight you.
Consistent uptime
An SLA backed by a status page that shows the incident rather than just the colour.
Keyboard shortcuts
Every destination reachable without the mouse, and discoverable without the docs.
Currency conversion
Settle in one, charge in thirty, with the rate recorded against each charge.
Enterprise security
Role-based access, audit trails and fine-grained controls that record who saw what.
Resource insight
Queue depth, error rate and latency at a glance, alerted on before they bite.
Blazing performance
Edge-cached reads and a dashboard that stays responsive at a million rows.
What customers report
We replaced three vendors and a spreadsheet with this. The part that convinced the board was reconciliation: the number in the bank finally matched the number in the books, on the first close.
