POST
Create an address
Creates an explicit route for one local part on a domain. With an endpointId, matching mail is delivered to that webhook; without one it’s store-only (kept for retrieval). See Addresses & routing.
string
required
The domain the address belongs to (dom_…). Must be yours.
string
required
Everything before the @, e.g. support. 1–64 chars, lowercased; letters, digits, and ._+-.
string
A webhook endpoint (ep_…) to deliver to. Omit for a store-only inbox.
An explicit address claims that local part even without an endpoint — a store-only address opts that address out of the domain’s catch-all.
