With custom connectors, you can combine the flexibility of APIs with the easy-to-use awesomeness that is the Power Platform. While there are a lot of examples for simple connectors, custom connectors offer a variety of advanced but less well-known features. Let's change the less-know part! Did you know that you can have fields with dynamic option values? Or that you can create action where some fields are completely dynamic and loaded at runtime? You can even create custom connectors with custom triggers. We will spend little time on theory but instead are focusing on awesome features in live demos.
