# Update a contact field

`PATCH /api/reach/v1/profiles/{profileUuid}/contacts/fields/{fieldUuid}`

Rename a custom contact field and, for the choice types, replace its option set.

Options carrying a uuid are kept and relabelled, options without one are created, and any
existing option left out of the list is deleted along with the values contacts hold for
it. The field type and slug cannot be changed.
