Authentication
Send an API key as a bearer token. The key must carry the mail.manage permission; a key without it is refused with 403, not 404.
This endpoint takes no organisation id. Your key already identifies the organisation it belongs to, and the response is scoped to it.
Try it
Replace anything in angle brackets with your own values, and the key placeholder with a key from your dashboard.
curl -X POST https://api.zinndigital.com/v1/mail/services/{mailServiceId}/mailboxes \
-H "Authorization: Bearer zdk_live_…" \
-H "Content-Type: application/json" \
-d '{ "local": <string> }'Signed in? The API console in your dashboard fills in your real organisation id and your own key, and runs the request against the live API so you can see the actual response. Open this endpoint in the API console
Details
Creates `local@domain` and returns it **with its password, once**. The password is never stored and cannot be read back — a lost one is replaced by `resetMailboxPassword`, not recovered. `password` is `null` when the backend reconciled to a mailbox that already existed and refused to rotate a live password; show that as "we could not display a password", never as a blank one. Requires `mail.manage`. Fails `409` on a duplicate address, and `422` when the service is not live yet or the domain is at its mailbox ceiling.
