Site settings and site API keys
The site's configuration — names, emails, options, feature settings — and the provider keys a site uses for its own services.
Settings
/settings — every setting the site has, grouped by feature: name and tagline, admin and system email addresses, logo and brand, zone stylesheets, store options, affiliate rates, and so on. Change a value and save; it applies on the next page load.
A setting has a definition (its name), a value and a type (a constant, a variable, a list or a JSON document). Feature settings arrive when the feature is installed; you rarely need to add one by hand.
Site API keys
/sitekeys — provider keys that belong to this site rather than to your account: a payment processor's keys for this store, a mail provider for this domain, an AI provider for this site's chatbot. Add the provider, paste the key, save; the site uses it from then on. Custom providers can be added for functions and flows to use.
Keys that should follow you across sites (your OpenAI or Anthropic key) go in Integrations instead.
