The Flows reference section provides descriptions, details, and examples for blocks, TypeScript functions, and Flows Query Language (FQL).

## Blocks reference

Learn about each block's inputs, outputs, and setup options, in the [blocks reference section](/flows/reference/blocks/overview/). You can also see what blocks are often used together.

## TypeScript functions

Learn how and where you can [use TypeScript](/flows/reference/typescript/typescript-overview/) to enhance logic and functionality in the logic blocks of your Postman Flows.

## Flows Query Language
