App column type (deep link)

The App column type is used to navigate to a different view in the current app or to another app. The value in an App  column must be a deep link.

A deep link is a special text value that follows a particular format. There are two ways to create a deep link:

To learn more, get started with a sample app.

Note: In addition to being a normal column, App columns can be used with app launchers and app actions.

Learn how to deep link to a view in another app using LINKTOVIEW() by using the Change view on row selection sample app. This sample defines an action called Change View that uses the LINKTOVIEW() function to change the current view based on the View Name column in the Views table.

AppSheet provides the following functions to create deep links.

Function Description Examples
LINKTOAPP() Deep link to an app

Navigate to app MyApp-123 and displays its default starting view:

LINKTOAPP("MyApp-123")

LINKTOFILTEREDVIEW() Deep link to view with filtered row values

Note: The second argument is a filter expression over the rows in the view. This is similar to the filter in SELECT() expressions.

  • Navigate to the Order View and display Orders whose Order Status is Open:
    LINKTOFILTEREDVIEW("Order View", [Order Status] = Open) 
  • Navigate to the Customers Table View and display high-priority customers associated with the current sales rep:
    LINKTOFILTEREDVIEW("Customers Table View", AND([Sales Rep] = [_THISROW].[Sales Rep Id], [Priority] = High)) 
  • Navigate to the Students Table View and display students having ages younger than the current student:
    LINKTOFILTEREDVIEW("Students Table View", [Age] < [_THISROW].[Age])
LINKTOFORM() Deep link to a form with pre-filled values (current app, if not specified)

Note: In the following examples, the function pre-fills the [Store] column with the value Main Warehouse and the [Type] column with the value Wholesale. You can include any number of column name-column value pairs in the function.

  • Navigate to the New Order form in the current app:
    LINKTOFORM("New Order", "Store", "Main Warehouse", "Type", "Wholesale") 
  • Navigate to app MyOtherApp-123 and display the Other New Order form:
    LINKTOFORM("Other New Order", "Store", "Main Warehouse", "Type", "Wholesale", "MyOtherApp-123") 
LINKTOPARENTVIEW() Deep link to the parent view

Navigate to the parent view in the current app:

LINKTOPARENTVIEW() 

LINKTOROW() Deep link to a row (current app, if not specified)
  • Navigate to the Order Details view in the current app for the row having key order456
    LINKTOROW("order456", "Order Details") 

  • Navigate to the Order Details view in the current app for the row with the key value contained in [Order Detail ID]:
    LINKTOROW([Order Detail ID], "Order Details")

  • Navigate to app MyOtherApp-123 and display the Other Order Details view for the row with key order456:
    LINKTOROW("order456", "Other Order Details", "MyOtherApp-123") 
  • Navigate to app MyOtherApp-123 and display the Other Order Details view for the row with the key value contained in field [Order Detail ID]:
    LINKTOROW([Order Detail ID], "Other Order Details", "MyOtherApp-123")

LINKTOVIEW() Link to a view (current app if not specified)
  • Navigate to the New Orders view in the current app:
    LINKTOVIEW("New Orders") 
  • Navigate to the app MyOtherApp-123 and display the Other New Orders view:
    LINKTOVIEW("Other New Orders", "MyOtherApp-123") 

You can manually construct deep links by specifying the app name and link parameters, as described in the following sections and demonstrated in the examples.

Format tips:
  • Whitespace or other HTTP special characters in a deep link must be URL-encoded using the ENCODEURL() expression.
  • A deep link is a text value, not an app expression. The link must be enclosed in quotes.

App name

Your deep link can specify the app name. When no app name is specified, the current app name is assumed.

The app name is defined by the appName query parameter in the app URL when viewing the app in the editor or accessing the app in your desktop browser. (It is not equivalent to the Short Name of the app defined in Settings.) For example, in the following app URL the app name is ShiftManagement-3518598:
https://www.appsheet.com/template/AppDef?appName=ShiftManagement-3518598&appId=58bb9fcc-b701-462a-87fd-34129fe8fcba&quickStart=False#Data.Columns.Admin%20Scheduled%20Shift

Link parameters

Your deep link can control which view and row is displayed by specifying optional link parameters following a # symbol. Link parameters are separated using the & symbol. The following link parameters are supported:

Link parameter Description
view  Name of the UX view to be displayed. If any link parameters are specified, this parameter is required.
row Key of the row to be displayed. This parameter is required for some views and is optional for others. 
mapcolumn Name of the Address or LatLong column on which the Map view is based. This parameter is used for Map view controls.
at Minimum timestamp required for the data. Setting the timestamp to a time in the future can force the app to sync to pick up data changes rather than work with stale data. The most common use for this parameter is in sending anemail, SMS, or push notification with a link to a particular data entry in the app. 

Examples of manually constructed deep links

The following table provides example of manually constructed deep links.

Deep link to Example Description
App "MyApp-123" Navigate to app MyApp-123 and display its default starting view.
View in the current app "#view=New Orders" Navigate to the New Orders view in the current app.
View in another app "MyOtherApp-123#view=Other New Orders"  Navigate to app MyOtherApp-123 and display the Other New Orders view.
View and row in the current app "#view=Order Details&row=order456"

Navigate to the Order Details view in the current app and display the row with key order456.

CONCATENATE("#view=Order Details&row=", ENCODEURL([Order Detail ID])) 

Navigate to the Order Details view in the current app and display the row with the key value contained in [Order Detail ID].

CONCATENATE(LINKTOVIEW("Inspections"), "&at=", ENCODEURL(NOW()+1)) Navigate to the Inspections view in the current app and force a sync.
View and row in another app "MyOtherApp-123#view=Other Order Details&row=order456"  Navigate to app MyOtherApp-123 and display the Other Order Details view for the row with key order456.
  CONCATENATE("MyOtherApp-123#view=Other Order Details&row=", ENCODEURL([Order Detail ID]))  Navigate to app MyOtherApp-123 and display the Other Order Details view for the row with the key value contained in field [Order Detail ID].
App and force a sync CONCATENATE(LINKTOAPP("MyApp-123"), "#at=", ENCODEURL(NOW()+1))  Navigate to app MyApp-123, force a sync, and display its default starting view.
