Address	`https://api.hanzo.ai/v1/marketing/unsubscribe`
Method	`GET`
Operation	`get_marketing_unsubscribe`
Auth	`Authorization: Bearer $HANZO_API_KEY`

Is the PUBLIC one-click endpoint (no principal): a recipient clicks the signed link in an email footer. The token binds (org, channel, address), so a caller can only opt OUT exactly the tuple it was minted for — never another address and never another org. An invalid token is refused, and a deployment with no KMS-sealed key refuses rather than accepting anything.

Request

4 fields.

Field	In	Type	Required	Description
`org`	query	string	—	Org is the org the link was minted for.
`channel`	query	string	—	Channel is the surface to opt out of.
`address`	query	string	—	Address is the recipient to opt out.
`token`	query	string	—	Token is the HMAC over (org, channel, address).

Response

Status	Body	Meaning
`200`	Unsubscribed	ok

200 body — 3 fields.

Field	In	Type	Always	Description
`address`	body	string	—	Address is the recipient now opted out, normalized (lower-cased, trimmed) to the form the send gate matches on — so it can differ in case from the address the…
`channel`	body	string	—	Channel is the ONE surface opted out of: email, sms, social, meta, google or tiktok.
`unsubscribed`	body	boolean	—	Unsubscribed is always true here: the opt-out is idempotent, so a second click on the same link confirms the same thing rather than reporting nothing changed.

Failure carries the platform error shape — see Errors.
