This page introduces the SenderKit public REST API. The endpoint pages in this section are generated from the OpenAPI specification and cover dispatching messages, listing message history, and reading or rendering stored templates.

Authentication

All endpoints require a Bearer API key. The sk_live_ / sk_test_ prefix selects the environment; the prefix is a hint for humans, the secret is the full token. 
Authorization: Bearer sk_live_xxx
See Authentication for how to create and manage keys.

​
Sends are asynchronous

POST /v1/send enqueues the message and returns 202 with status: "queued" (or "scheduled" when the request includes a future scheduledAt). Delivery happens out of band — poll GET /v1/messages to observe progress.
