Retrieve a marketing campaign
One campaign, including its body, which is the only place this API serves it. READ status TOGETHER WITH scheduled_for. Unscheduling a campaign returns it to draft but LEAVES scheduled_for populated, so a client that decided “is this armed” from the timestamp alone would report a disarmed campaign as armed forever. status is the answer; scheduled_for is when it was, or would have been, due. completed_at stays null on a cancelled campaign, which is how an abandoned send is told apart from a finished one.
Authorizations
A secret API key. Publishable keys cannot reach this API. A key may carry an expiry, and an expired key is refused exactly like an unknown one, with a 401 that names no reason; check the key's expires_at in the dashboard rather than inferring it from a response. When a merchant rolls a key's secret they choose a grace window of up to 3 days, and for its duration BOTH the new secret and the one it replaced authenticate, so an integration moves over on its own deploy schedule instead of at the instant the button is pressed. Move before the window closes: after it, the old secret is refused. Nothing else about this contract moves with a roll. The key keeps its id and its scopes, so the only thing an integration updates is the credential itself.
