SDKs & tools

You build on Fabrik through the official TypeScript SDK. The CLI complements it by generating typed keys for your message definitions.

The TypeScript SDK is the supported client today. It covers SMS, email, WhatsApp, managed messages, verification, sender IDs, wallet reads, and webhook operations. SDKs for more languages will follow once the API reaches a stable release.
