Send a test delivery
Queues a synthetic webhook.test event. It travels the full path — same signing, same retry curve, same delivery log — so a passing test proves real events will arrive too. Requires the endpoint to be subscribed to webhook.test.
Authorization
bearerAuth 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.
