API

Send mail and drive a mailbox from your own code, with a workspace API key.

What this is

A REST API over the same mailbox the app uses. Send, schedule, cancel and retrieve messages; read and organise threads; work with drafts, labels, templates, rules, contacts, audiences and domains. It authenticates with a key you issue yourself, enforces scopes, and refuses any From address the key was not given.

The API is on in every environment. What decides access is the workspace key you issue in Settings, scoped when you create it, revocable at any time.

A key belongs to a **workspace** (the mailbox it was issued in) rather than to the person who created it. It keeps working after that person leaves, and it does not widen the day they are granted an address somewhere else.
