# Yokoy **Canonical:** https://apis.io/providers/yokoy/ **Website:** https://yokoy.io/ **APIs profiled:** 22 Yokoy (now part of Perk / TravelPerk) is an AI-powered spend-management platform for expenses, supplier invoices and corporate cards. Its public REST API (OpenAPI 3.0, 105 operations) imports master and configuration data into Yokoy and exports financial data — expenses, trips, invoices, transactions, journal entries and FX rates — to third-party ERP and accounting systems. Authentication uses the OAuth2 client-credentials flow; every request is scoped to an organization ID and most resources to a legal entity (company). The API spans expenses, invoices, trips, transactions, company cards and card accounts, cost centers, categories, tax rates, suppliers, users, policies, tags and finance-export tasks. ## Kin Score — 40.3 / 100 (developing) Scored 2026-08-21 under rubric 0.12.0.
