Getting Started & Authentication
You get your API key from the Corpenza panel: your company → API tab → New Key. The key is shown only once and is always bound to a single company — it cannot access other companies' data. All requests use HTTPS with the Authorization header.

Scopes are chosen at key creation: read:company, read:invoices, read:expenses, read:reports, read:usage, write:invoices, write:expenses. write:* endpoints require an active Corpenza API package.
