inbox_id · required · string The Inbox ID or the inbox email address, such as `[email protected]`. A value that contains `@` must be a valid email address, and any other value must be a UUID, or the request returns a 422. The address match is case-insensitive and never falls back to the inbox `name`. An address that matches no inbox returns a 404.

Body application/json

2 body fields

name · required · string — New internal name for the inbox. Recipients do not see it. Between 1 and 64 characters after trimming.
from_name · optional · string — The name recipients see when mail is sent from this inbox. A plain name, not a `Name <email>` address. Max 78 characters. It cannot contain a colon, `<`, `>`, line breaks, or other control characters. An email address inside the name must be on a domain the team has verified for sending. An empty string removes it.
