The Resend toolkit integrates Arcade with Resend to send and manage transactional email from LLM-powered workflows.
Capabilities
- Send & schedule email — Send transactional email immediately or queue it for future delivery using a
scheduled_attimestamp; returns the Resend-assignedemail_id. - Manage scheduled email — Reschedule or cancel queued emails before they are sent using their
email_id. - Email status retrieval — Fetch details and current delivery status of any sent or scheduled email by ID.
Secrets
RESEND_API_KEY — A Resend API key used to authenticate all requests. Obtain it from the Resend API Keys dashboard (requires a Resend account). Create a key with at least Send access for sending/scheduling; full access is required if you need to retrieve or cancel emails via the API. Copy the key immediately after creation — Resend does not display it again.
