Connectors are one of the superpowers of the Microsoft Power Platform. They link the Power Platform to a vast array of external services and applications. Over 1200 connectors are available now out of the box. But – what if the API you want to connect to doesn’t have an out of the box connector? Or the existing connector doesn’t do what you need? Or your company has custom APIs that they want to use with the Power Platform? APIs change all the time and that means connectors might not have the newest features.

With custom connectors, you can create your own connector that connects to an API. You have control over the custom connector, so you can include REST API endpoints in the custom connector that can help you automate scenarios with the Power Platform products like Power Apps, Power Automate and Copilot Studio.

Service principal authentication was not an option for custom connectors until recently. Now, in the custom connector wizard, you can turn on service principal authentication. This opens up many possibilities that were not possible before. For instance, you can now use custom connectors to authenticate to the Graph API, which has many operations that could take advantage of this.
