# SDK Generator | Postman API Platform

> Generate production-ready client SDKs from your OpenAPI spec in TypeScript, Python, Java, PHP, Go, and C#. No boilerplate, no manual configuration.

## SDK Generator

Ship client libraries your developers actually want to use.

---

## Generate typed, production-ready client SDKs from any API spec

### One-click SDK generation

Connect your spec and produce a complete, typed client library in seconds.

### Multi-language support

Generate SDKs in TypeScript, Python, Java, PHP, Go, and C# from a single OpenAPI spec.

### Always in sync

Regenerate your SDK whenever your spec changes so client libraries never fall behind your API.

---

## Create up-to-date SDKs in seconds with AI

Postman AI reads your spec, applies the update you describe in plain language, and regenerates typed client libraries in one action so your SDK stays current without manual edits or context switching.

---

*CAPABILITIES*

### From spec to typed, distributable SDK in one workflow

Postman SDK Generator works directly from your Postman collection. When your API changes, one command regenerates the SDK. No spec exports, no external tooling.

### Produce typed client libraries from your spec

SDK Generator reads your OpenAPI spec directly and produces a client that matches parameters, response types, and error handling. Change your spec in Spec Hub and regenerate the SDK in the same session.

### Generate SDKs in leading languages

Provide the same API coverage in every language your consumers use so Typescript, Python, Java, PHP, Go, and C# clients all behave identically.

### Include your SDK in your Postman workspace

Give developers access to everything they need, from the collection and docs to the SDK, all in one place.

### CI/CD generation

Trigger SDK generation automatically when your spec changes in your CI pipeline.

### Spec validation

SDK Generator validates your OpenAPI spec before generating so you catch schema errors before they reach consumers.

### Multi-version SDKs

Maintain SDKs for multiple API versions simultaneously so your API consumers can migrate at their own pace.

> An API-first approach with Postman enables us to offer developers increased flexibility, accelerated time to market, and scalability.

## Broken collaboration leads to broken APIs.

Ninety-three percent of API teams still face collaboration blockers. The 2025 State of the API report reveals how you can unlock the productivity gains that API-first promises, but scattered tooling prevents.
