Connectors are integral components of the Microsoft Power Platform, they function as the proxies or wrappers that facilitate communication between different systems, services, platforms, and data. They enable data flow and create a bridge for the exchange of information and functionality across a variety of different platforms, interfacing between disparate applications and services.
Specifically focused on PL-100 Microsoft Power Platform App Maker exam, connectors are key to understand as they play a pivotal role in app creation, data manipulation, and integration of various services into a cohesive solution.
Types of Connectors
There are essentially three types of connectors available in the power platform:
- Standard Connectors: These are pre-built connectors, ready-to-use, and offer connections to a wide range of commonly used applications and services like Outlook, SharePoint, Dynamics 365, Twitter, Azure and many more.
- Premium Connectors: These offer connections to services that are often specialized, enterprise focused or niche, and usually require additional licensing to use. Premium connectors include services like Salesforce, the Common Data Service, and others.
- Custom Connectors: These are built by users, developers or Microsoft partners to connect to data and services that aren’t available through standard or premium connectors. Users or developers can build these connectors themselves to cater to their specific needs.
Using Connectors in Power Apps
In the context of Power Apps, connectors are used to fetch data from a database or other service, manipulate that data in some way and then possibly write the manipulated data back into that service. For instance, you might connect Power Apps to SharePoint through SharePoint Connector to fetch data from a SharePoint list, display that data in Power App, allow users to interact with that data, and store their responses back into SharePoint.
Here is an example of how we can use a connector in a Power App:
ClearCollect(ContactData, ‘[dbo].[Contacts]’)
In this example, ‘[dbo].[Contacts]’ is the connector being used to retrieve Contacts data from the database and store it in the Power Apps collection ‘ContactData’.
Benefits of Using Connectors
Connectors offer several advantages. Firstly, they abstract the underlying service complexities, meaning an app maker doesn’t necessarily need to know the specific technicalities of the services they’re working with, the connector will handle it. Secondly, the uniformity of connectors means that once you’re familiar with one, you can easily understand and work with others. Finally, with over 300 pre-built connectors and the possibility to create custom ones, connectors offer flexibility and accessibility to a large variety of services and data sources.
Conclusion
Understanding and effectively utilizing connectors is essential for anyone preparing for the PL-100 Microsoft Power Platform App Maker exam. Connectors facilitate data accessibility from a wide range of services, simplifying the process of app data integration. Therefore, a deep understanding of using connectors expedites the building and deploying process of complex and efficient apps on Power Platform.
