Install the SDK

Supported languages, package managers and minimum runtime versions.

Last updated Oct 21, 2026

Every SDK wraps the same REST API, so you can mix languages across services without changing your data model.

Supported runtimes

terminal

npm install @tessera/sdk # or pip install tessera # or go get github.com/tessera/tessera-go

Keep your secret key in an environment variable. The SDK reads TESSERA_KEY automatically when you don’t pass a key to the constructor.
