# API Client | Postman API Platform

> Use Postman's API client to create and save REST, SOAP, and GraphQL queries. Send requests, inspect responses, and easily debug APIs.

## API Client

Send requests, inspect responses, and debug any API in seconds.

[Read Docs](https://learning.postman.com/docs/getting-started/basics/using-api-client)

---

## Explore, test, and debug APIs without writing code

### Every protocol in one tool

Create and execute any HTTP, GraphQL, gRPC, WebSocket, or MQTT queries from a single interface so your team stops juggling separate clients.

### Authentication made simple

Configure any auth method from a dropdown without manually crafting headers, tokens, or refresh flows.

### Scriptable workflows

Chain requests, validate responses, and automate multi-step scenarios with JavaScript that runs before and after every request.

---

## Debug any API using prompts

Postman AI reads your request, inspects the response, writes test assertions, and suggests fixes so you spend less time diagnosing and more time building.

*CAPABILITIES*

### Build, send, and save complex requests on a single platform

Postman's API Client gives you a single interface for building, testing, and debugging APIs.

### Organize requests with collections and environments

Group requests into collections by project, team, or workflow. Switch between dev, staging, and production environments with one click so every request hits the right server.

### Inspect every detail of the response

View the status code, response time, and response size. Postman's automatic language detection, link and syntax highlighting, search, and text formatting make it easy to inspect the response body.

### Visualize your data

Easily turn API data into shareable charts and graphs. Developers can harness HTML5, JavaScript, and CSS or bring in many of the available charting and graphing libraries to create rich visualizations.

### Variables

Use global, collection, and environment variables to keep values dynamic and reusable across requests. Store sensitive data in session variables that remain local to your machine and are never synced to your team.

### Request history

Keep track of past requests. Every request you send is saved automatically so you can replay, compare, or recover past calls.

### Debugging console

See every request and response in the console with timestamps, headers, and body payloads. Log variables from your scripts and trace execution step by step.

> Everything you need for APIs can be found in the Postman API Platform. It has accelerated so many processes. Customers can onboard and begin using APIs in under three minutes.

## 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.
