Build a Custom Fake API Connector From Scratch in Copilot Studio!

Creating a fake API can be an invaluable skill when you're building a prototype, testing new features, or just need a temporary data source without the complexity of a real one. This video is all about how you can use Copilot Studio to build a dummy API and then use it with an agent to see the power of generative orchestration in action.

You'll learn how to build a custom connector that returns different data based on the action called, all with the help of C# and Copilot. We'll walk through the process of generating sample JSON, importing it into your custom connector, and then testing it within a Copilot Studio agent. This is the perfect way to build a proof of concept or just experiment with a feature that doesn't have an existing API.
