Bulk import suppressions
Carry existing unsubscribes over BEFORE your first send, so people who already opted out never hear from you again. Only manual and unsubscribe are importable — bounces and complaints are facts the provider reports through webhooks, and asserting them by hand would corrupt the severity ladder.
bearerAuth writeAuthorizationBearer <token>An API key from the dashboard under Settings → API keys, sent as Authorization: Bearer aem_….
Authorization has two independent axes.
The scope is ranked — a key satisfies any requirement at or below its own tier:
read— see messages, contacts and metrics. Changes nothing, and cannot send.write— everythingreaddoes, plus managing templates, contacts, automations, segments and suppressions. This is what editing a template needs.admin— everythingwritedoes, plus sending configuration: domains, senders, webhook registration, kill switch, daily cap, brand.
There is no approve scope. It was a rung once; it is not one now, and a key requested with it is rejected.
The approval grant (can_approve) is a separate boolean, not a rung. Delivering mail to a real inbox needs write and the grant. Keeping them on separate axes is what makes the review gate a control rather than a convention: a key that may propose is not automatically a key that may approve its own proposal.
Give your application the lowest tier that works. Most need write and the grant — the dashboard mints that combination as Send + manage; Manage only is the same rung with the grant withheld.

Idempotency-Key?stringMakes a retry safe (1–256 chars, kept 24 hours). The same key with the same body replays the first success with Idempotency-Replay: true; the same key with a different body, or while the first request is still running, is 409 conflict. A failed request releases its key. Use a value tied to the thing you are creating, e.g. onboarding/user_42.
