SDKs & CLI

One API, nine official clients

Typed SDKs for Node.js, Python, Go, Ruby, PHP, Rust, Java, .NET — plus a CLI — each published to its native registry and generated from the same API contract, so they never drift.

Every client covers the full REST surface — sends, batches, scheduling, campaigns, audiences, domains, webhooks, and templates — with idempotency keys and typed errors. Anything that speaks HTTPS can use the API directly, and AI agents can drive it through the MCP server and agent skills in the docs.
