Developer platform

One integration for customer communications.

Use SendOne through a REST API, TypeScript or Python SDK, signed webhooks and a sandbox designed for fast, confident integration.

send-message.ts

await sendone.messages.send(({
  to: customer.id,
  channel: "sms",
  template: "order-shipped",
  data: ({
    orderNumber: "SO-1042"
  })
}));

Stable, resource-oriented primitives with idempotency, request IDs and clear errors.

First-class SDKs for modern application stacks, with more languages planned.

Signed delivery events, retries and consistent payloads across supported channels.

Trace every request, routing decision, provider attempt and delivery outcome.

Scoped test and live credentials with environment separation and rotation.

Develop and validate message flows before moving real customer traffic.

Built on SendOne Core

A shared foundation—not another silo.

Every interface uses the same identity, consent, templates, routing, provider adapters, events, and logs.

One contact and consent model

One message lifecycle

One provider abstraction layer

One place to inspect delivery
