SDKs

Official SDKs wrap the REST API in idiomatic code for your language. They handle authentication, retries, and error types, so you don’t hand-roll HTTP.

​

What they cover

Both SDKs currently support outbound email — send a message and look up what happened to it. Everything else in the API is available over REST; see the API reference.

​

What you get

• Authentication handled — the key is read from the environment, validated before any request, and sent only in the Authorization header.
• Typed errors — branch on an exception type instead of parsing status codes.
• Safe retries — reads retry with backoff; sends never replay a request that might already have delivered mail.
• Secrets kept out of logs — the client redacts your key when printed, and no error message ever carries it.

​

Using another language?

The API is plain REST with JSON, so any HTTP client works. Start with the quickstart, then browse the API reference for a live console.
