This category covers the Integrations course, the technical core of the Foundations program.
Integrations is where you connect n8n to the outside world. It covers HTTP requests, webhooks, API authentication, pagination, flow logic with IF, Switch, and Loop, execution order, sub-workflows, Data Tables, and error handling. All the exercises use simulated APIs hosted by the Academy, so you do not need any external accounts or API keys.
This is the densest course in the program, so do not hesitate to ask. Post your question with the unit you are on, what you expected, and what you are seeing. Screenshots of your node setup help a lot here.
