API-First Platform for Developers
Build with a unified API that connects email, AI, auth, forms, and more. One SDK, one dashboard, one bill — designed for developers who ship fast.
Pain Points, Solved
Common Pain Points
Too many vendor APIs to manage
Every communication channel means another SDK, another dashboard, another billing relationship. Context-switching between providers slows you down.
Inconsistent developer experience
Each vendor has different auth patterns, error formats, rate-limit behaviors, and webhook schemas. Nothing feels cohesive.
Vendor lock-in limits flexibility
Switching providers requires rewriting integrations, migrating data, and retraining the team on new APIs.
How Transactional Helps
One SDK for every channel
A single TypeScript (or REST) SDK covers email, SMS, support, forms, calendar, AI, and auth. Install once, import what you need.
Consistent API design
Every endpoint follows the same auth scheme, error format, pagination pattern, and webhook structure. Learn one, know them all.
Modular architecture, zero lock-in
Enable only the modules you need. Each module works independently, so you can adopt incrementally and swap freely.

Overview
Transactional is built API-first for developers who want to stop stitching together dozens of SaaS tools. Instead of managing separate accounts for email (SendGrid), chat (Intercom), forms (Typeform), auth (Auth0), and AI (OpenAI), you get a single platform with a unified SDK.
Why developers choose Transactional
Ship faster with fewer dependencies
Every module in Transactional shares the same authentication, error handling, and webhook infrastructure. That means less boilerplate, fewer edge cases, and faster iteration cycles.
First-class TypeScript support
The SDK is fully typed with auto-generated types from our API schema. Get autocomplete, type safety, and inline documentation in your editor without leaving your flow.
Built for modern stacks
Whether you are on Next.js, Remix, Astro, or a plain Node server, Transactional fits in. Server components, edge functions, and serverless deployments are all first-class citizens.
Common patterns
- SaaS onboarding flows — Auth signup, welcome email, and calendar booking in one integration
- AI-powered apps — Route LLM calls through the AI Gateway, send results via email or chat
- Internal tools — Forms for data collection, email for notifications, observability for monitoring
