add_sending_domainAdd a domain and get the exact DNS records to publish

}Prefer a key over OAuth? Add Authorization: Bearer <your-site-api-key> as a header. Get the key from your site in the dashboard.
OAuth 2.1 — one click
Your AI tool opens a browser, you approve access and pick which site to grant, and it's connected. PKCE, dynamic client registration, short-lived tokens. No key to copy.
API key — no browser
Send your site's API key as a Bearer header — the same key the WordPress plugin and REST API use. Ideal for headless setups and CI.
