Scenario:
Qualified leads must be collected from local bike fairs.
Adventure Works Cycles uses a Power Apps app for local bike fairs to attract new customers.
By using a Dynamics 365 connector, you can create flows that initiate when an event occurs in Dynamics 365, or some other service, which then performs an action in Dynamics 365, or some other service.
In Power Automate, you can set up automated workflows between your favorite apps and services to synchronize files, get notifications, collect data, and more.
