This is but an introduction to what Flow can do. It can connect to a wide range of platforms, from simple Excel spreadsheets to non-Microsoft platforms such as https://www.salesforce.com. Default templates can also facilitate integration by configuring and fine-tuning reusable Flows.
In this recipe, we implemented a simple one-step flow that replicates data between two platforms. Flow can deal with multi-step processes as well as conditional branching.

If you are after some more control over your integration, consider using Azure Logic Apps at https://azure.microsoft.com/en-us/services/logic-apps/.
