The source code for Microsoft Power Platform Connectors is partially available, depending on the type of connector. Microsoft hosts an open-source repository on GitHub for Power Platform Connectors, which includes custom connectors, certified connectors, and related tools for Microsoft Power Automate, Power Apps, and Azure Logic Apps. You can find this repository at

. This repository contains:

• Custom Connectors: Sample connectors that are fully functional and can be deployed for extension and use. These are maintained by the open-source community and serve as examples or starting points for developers.

• Certified Connectors: Connectors built by partners who own the underlying service. These are open-sourced as a requirement of Microsoft’s certification program, allowing community contributions. They are available out-of-the-box in the Power Platform.

• Independent Publisher Connectors: Submitted by developers or companies who do not own the service behind the connector. These are also open-sourced and maintained by the community.

However, Microsoft’s native connectors (standard and premium) are not open-sourced. These are proprietary and maintained internally by MicroFor Providers in the context of Power Platform (e.g., Terraform providers for Power Platform), the source code for the Power Platform Terraform Provider is available at GitHub - microsoft/terraform-provider-power-platform. This provider allows interaction with Power Platform resources like connectors and environments via Terraform.soft, so their source code is not publicly available. For those looking to understand the parameters or functionality of these connectors, Microsoft provides documentation on Microsoft Learn or suggests building custom connectors to interact with similar APIs.
