buy_set_default_address

Sets the default delivery address on a linked merchant account, using an id from buy_addresses. New orders default to it.

Not advertised in tools/list by default — the buy tool covers this conversationally. Expert integrations can still call it by name.

Parameters

Parameter	Type	Required	Description
`merchant`	string	Yes	Merchant slug (for example `doordash`)
`address_id`	string	Yes	The address id from `buy_addresses`

A confirmation that the default delivery address is set, including the address id. Failures return a short error message.
