Tutorial: Build an API from Start to Finish

Build your first API from design to deployment using Anypoint Code Builder. Design an API spec, implement the logic, test locally, and deploy to CloudHub 2.0 to learn the complete MuleSoft API development workflow.

What You’ll Build

A simple "Hello World" API that:

  • Returns a greeting message when you call it

  • Demonstrates the complete API development lifecycle

  • Runs in the cloud and is accessible from anywhere

What You’ll Use

  • Anypoint Code Builder

    Your cloud-based development environment for designing and building APIs.

  • MuleSoft Vibes (Optional)

    An AI assistant built into Anypoint Code Builder that generates API specs from simple descriptions. Instead of writing code, you describe what you want. If you don’t have access to MuleSoft Vibes, you can create API specs manually in Anypoint Code Builder.

  • CloudHub 2.0

    MuleSoft’s cloud platform where your APIs run. Deploy once and your API is accessible worldwide with automatic scaling and reliability.

  • Runtime Manager

    Your operations dashboard for monitoring deployed APIs, viewing logs, and managing applications running on CloudHub 2.0.
