Pleo
Pleo is a business spend management platform that issues smart company cards to employees, enabling real-time expense tracking, receipt capture, and automated bookkeeping. The Pleo REST API lets developers automate workflows, sync accounting data, manage users and cards, and build custom integrations against accounting systems. The API supports OAuth 2.0 (with PKCE) and API key authentication with a scopes-based permission model, and offers both a sandbox and production environment. Pleo also runs an App Marketplace where partners can publish integrations available to thousands of businesses across Europe.
