Detalhes

**Unauthenticated by design** — the caller is a Cloudflare Email Routing Worker with no Zinn® credential, so an HMAC over `"<timestamp>\n<body>"` in `X-Zinn-Signature` *is* the authentication. The timestamp is inside the signed material and its skew is bounded, so a captured request cannot be replayed later. This is the inbound half of support email. Before it existed the platform sent notifications from an address that accepted mail and discarded it: a customer replied, nothing happened, and neither they nor the waiting staff member was told. The ticket is resolved from a **signed token inside the `Message-ID`** we set on the outbound notification — nothing in the body, the `From` address or any other header selects a tenant, because all of those are chosen by whoever sent the mail. Redelivery is the normal case, not the exception: email is at-least-once and a lost response guarantees a retry, so a message already filed answers `200` with `duplicate: true` rather than appending a second copy. ⛔ Unlike the gateway webhooks, a message that **cannot be routed is answered `422`**, not `200`. A 2xx tells the Worker to accept the mail, and an accepted message that reaches no ticket is the exact defect this endpoint exists to remove; `422` makes the Worker reject it so the sender's own mail server bounces it back to the customer.

Parâmetros

Nome	Tipo	Obrigatório	O que é
`X-Zinn-Timestamp (header)`	`string`	Sim	Unix seconds. Inside the signed material; skew-bounded to five minutes.
`X-Zinn-Signature (header)`	`string`	Sim	`sha256=<hex>` HMAC over `"<timestamp>\n<body>"`.

Corpo da requisição

Nome	Tipo	Obrigatório	O que é
`from`	`string`	Sim	The envelope sender. Forgeable, and treated as such — it is checked against the ticket's org and the answer becomes a flag, never a permission.
`to`	`string`	Não	—
`message_id`	`string`	Sim	The message's own `Message-ID`. Stored, and unique, so a redelivery cannot append twice.
`in_reply_to`	`string`	Não	Carries the signed ticket token when the customer replied to one of our notifications.
`references`	`string`	Não	The full thread chain. Searched as well as `in_reply_to`, because a reply to the third message in a thread puts our id here and not there.
`subject`	`string`	Não	—
`text`	`string`	Não	The message body. Quoted history is trimmed engine-side and the result is length-bounded.

Resposta

Nome	Tipo	Obrigatório	O que é
`ticket_id`	`string`	Sim	—
`duplicate`	`boolean`	Sim	This exact message had already been filed — a success, not an error.
`sender_verified`	`boolean`	Sim	Whether the sender is a known address on the ticket's org. `false` still files the message, flagged for staff.
`reopened`	`boolean`	Sim	Whether filing it moved a `solved` ticket back to `open`.
