Update a subscriber
update_subscriberIdempotent
Updates the first name (first_name), last name (last_name) and custom fields (fields, by technical key) of an existing subscriber. The email address cannot be changed: it is the identifier. Tags are managed with tag_subscriber. Unknown fields are rejected (400). The response contains the updated record and the fields keys that were ignored (ignored_fields).
