In PowerApps, add a data connection to an existing app or to an app that you're building from scratch. In this topic, you use PowerApps Studio, but you can also use powerapps.com, as the Manage connections topic describes.
Your app's data connection can connect to SharePoint, Salesforce, OneDrive, or one of many other data sources.
Your next step after this article is to display and manage data from that data source in your app, as in these examples:
Most PowerApps apps use external information called Data Sources that is stored in cloud services. A common example is a table in an Excel file stored in OneDrive for Business. Apps are able to access these data sources by using Connectors.
The most common data sources are tables, which you can use to retrieve and store information. You can use connectors to data sources to read and write data in Microsoft Excel workbooks, SharePoint lists, SQL tables, and many other formats, which can be stored in cloud services such as OneDrive for Business, DropBox, SQL Server, etc.
Data sources other than tables include email, calendars, Twitter, and notifications.
Click or tap New on the File menu (near the left edge).
On the Blank app tile, click or tap Phone layout .
In the right-hand pane, click or tap the Data tab, and then click or tap Add data source.
Note: If you're updating an existing app and Add data source doesn't appear in the right-hand pane, click or tap Data sources on the View tab of the ribbon.
If the list of connections includes the one that you want, click or tap it to add it to the app. Otherwise, skip to the next step.
Click or tap New connection to display a list of connectors.
Scroll through the list of connectors until the type of connection that you want to create appears (for example, Office 365 Outlook), and then click or tap it.
Click or tap Create to both create the connection and add it to your app.
Some connectors, such as Microsoft Translator, require no additional steps, and you can show data from them immediately. Other connectors prompt you to provide credentials, specify a particular set of data, or perform other steps. For example, SharePoint and SQL Server require additional information before you can use them.
