Billingo is a Hungarian online invoicing and billing platform for businesses. It provides tools for issuing invoices and receipts and for integrating external systems with its billing workflows.
Billingo exposes one documented REST API surface: Billingo API v3 at https://api.billingo.hu/v3, authenticated with a Billingo-issued API key in the `X-API-KEY` header; no public GraphQL API, MCP server, or CLI was found.
- Billingo API v3discovered
Sign in to your Billingo account, then generate a V3 API key from the app. The developer docs say to go to Billingo Developer Portal: API kulcs generálása or in the app open Settings / Integrations / API-kulcsok, then click Új API-kulcs generálása. The marketing FAQ also says API keys are generated under Settings (gear icon) / API kulcsok: API és tömeges számlagenerálás FAQ.
