Init options

Appearance is normally managed in the dashboard — no code changes needed. Inline options win when both are set, which makes them useful for a per-site override without touching the bot's configuration.

Option	Type	What it does
idrequired	string	Your bot key from the dashboard Install tab. Starts with bot_ and is safe to expose — it is bounded by your domain allow-list, not by being secret.
title	string	Overrides the header title set in the dashboard.
greeting	string	Overrides the first message the visitor sees. Naming what the assistant covers here produces better questions than an open invitation does.
accent	string	Hex colour overriding the dashboard accent, e.g. "#0F9D6B".
position	"right" \| "left"	Which corner the launcher sits in. Defaults to "right".

All options together

window.MatterChat = window.MatterChat || { q: [] };
window.MatterChat.q.push(["init", {
  id: "YOUR_BOT_KEY",
  title: "Acme Support",
  greeting: "Ask about shipping, returns, or sizing.",
  accent: "#0F9D6B",
  position: "right",
}]);
