API Overview

The current CostSync release does not expose a public API.

ℹ️

Note

There is no API-key generation flow, public base URL, or confirmed plan entitlement for API access. The routes used by the embedded app are authenticated internal routes and are not supported for external integrations.

For supported integrations, use CSV import/export or the accounting exports included with Growth and Pro. If you need an integration that is not covered by those workflows, contact support.
