Creating a Custom Connector for Power Apps


Power Automate has become a key part of the power platform. Power Automate is a strong, built-in workflow engine that is meant to quickly automate workflows along with securely connecting on-premise data and cloud-based services ensuring that you can make most of your existing data. With Microsoft’s decision to shift from the classic workflows in Dynamics 365 CE, the use of Power Automate has become even more imperative. The Power Automate platform provides users with multiple connectors “APIs” that allow you to communicate and connect with the disparate systems / applications without coding.  However, not all connectors fit in the versatile business needs.
