For builders who want their apps to connect reliably with other services, from first requests to real traffic.

Almost every useful app talks to other software, whether it is calling an AI model, taking a payment or receiving an order. When those connections are built carelessly, apps fail in confusing ways, data goes missing and costs climb. Builders who understand APIs properly ship faster and spend far less time chasing mysterious errors.

This course starts with the basics and builds steadily to the way serious systems handle real traffic. It is taught live and hands-on, with real requests against real services, and review of what you build. You leave able to connect to almost any service, design APIs others find easy to use and understand what keeps a busy system steady.

What you will learn

  • Connect your apps to other services with confidence
  • Design APIs that other developers find easy to use
  • Build integrations that hold up when traffic and errors arrive
  • Understand how production systems keep busy APIs fast and stable

Course outline

The full material opens once you are enrolled.

  1. Module 1

    Speaking the language of the web

    • Your first conversation with an APIMake your first real request and understand every part of the reply.
    • APIs people enjoy usingDesign endpoints that make sense to anyone who calls them.
    • Who gets inControl access to your services the way production teams do.

  2. Module 2

    Built to hold up

    • When the data will not fit on one pageWork through large amounts of data without missing a record.
    • Playing well with busy servicesStay within a service's limits and recover gracefully when it pushes back.

  3. Module 3

    Ready for real traffic

    • The front door to your servicesSee what stands in front of a serious API and why it matters.
    • Sharing the loadKeep your app responsive as more and more people use it.
    • Behind the scenes of a live systemSee how a production setup keeps a busy API fast and steady.
