Say hello

event_say_hello

Idempotent

Sends a hello (a connection request) from the person to somebody listed in their event matches; when it is accepted, a conversation opens that both can read and answer from the app, the web page or an assistant. Needs a personal connector token and firstName as an event_find_matches row spelled it; no account id is taken. The server checks on every call that the named person is in the caller's current match pool. It is a single call: the hello is sent when the call succeeds. Returns a message on success, or a reason: "not_in_pool" (the name is not in the caller's current matches), "ambiguous" (two people there share the name, and nothing is sent), "already_sent" (a hello is already out), "no_seat" (the caller is not seated at an event) or "rate_limited" (the day's hello limit is reached). Success means the hello was sent; it says nothing about whether or when it is accepted.
