To start configuring the workflow, we have to first set up a connector. A connector can be a push connector or a poll connector. Push connectors are those in which Logic App is notified by the connector when the event is fired, whereas poll connectors are those in which the connector is notified by Logic App when the event is fired. Connectors are classified into the following categories:

• API Apps, Logic Apps, and Azure Functions.
• Microsoft Managed APIs: There are managed by Microsoft and contain some third-party and Microsoft-built APIs. These type of connectors include GitHub, Facebook, Dropbox, Azure Blog, SQL Azure, CRM online, SharePoint online, and others.
• Marketplace: These are also third-party and Microsoft-built APIs, but are managed by Microsoft. Marketplace has a large number of connectors available, and they are mostly hybrid connectors such as SAP Connector, IBM DB2, Oracle, BizTalk API Apps, and others.
