The API, on one page

Three reads and two writes, touring caravans and motorhomes on one key. Every call carries your key in the x-api-key header. 60 calls a minute per key. JSON in, JSON out. Every write is logged in your organisation's name.

Authentication

The key is shown once in the portal. Send it on every call. A missing or wrong key gets a 401 with a sentence saying so.
