Xero API changes & breaking changes
Accounting integrations fail quietly: a changed field in an invoice response doesn't crash anything, it just mis-books. Detektu diffs Xero's published OpenAPI contracts so ledger-relevant changes surface as findings, not month-end discrepancies.

Change model
How Xero ships changes
The release patterns that shape your integration risk.
Xero publishes per-domain OpenAPI contracts. Accounting is the flagship, alongside Assets, Bank Feeds, Files, Finance, Identity, Projects, and region-specific Payroll (AU, NZ, UK). Payroll in particular changes on regulatory schedules that have nothing to do with your release calendar.
Detektu diffs each contract independently and reports the exact operation and field, so a schema change in AU payroll stays quiet for a UK-only integration while a changed invoice field escalates for everyone booking revenue through it.
