}Scheduled messages
Schedule a message
Send a template, rendered with data, to one destination at schedule.send_at or the earliest moment after it that the delivery_conditions allow. recurrence repeats it. Credits are spent when each send happens, not now. Presence conditions are accepted in shape and refused with 422 until presence delivery is enabled. Send an Idempotency-Key to make retries safe.

}Authorizations
LithoBlocks API key obtained from your organization dashboard. The LithoBlocks MCP server also presents a Supabase-issued user session token here on the user's behalf; such a token acts as that user with the scopes their organization role allows.
Headers
Any unique string (a UUID is fine). Repeating a request with the same key and body within 24 hours replays the original response with Idempotency-Replayed: true instead of running again; the same key with a different body is a 409. Incomplete and 5xx outcomes are retained for reconciliation beyond 24 hours. Applies only on the documented endpoints. Never automatically change keys to bypass an uncertain outcome.
Required string length:
1 - 255Example:
"3f7d2c1a-9b4e-4f0a-8c6d-2e1b5a7c9d10"
