Invoke an action

You can invoke one the following types of actions using the API:

  1. Data: set the value of a column
  2. Grouped: execute a sequence of actions.
    All actions invoked in the Grouped sequence must be either Data: set the value of a column or Grouped: execute a sequence of actions.


Use a URL in the following form to invoke the API:



  • {appId} specifies the GUID of the AppSheet application.
  • {tableName} specifies the name of the table.

Request body

The HTTP request body contains:

  • The action name.
  • Optional properties such as Locale, Location, and Timezone.
  • One or more Rows elements specifying the key field values of the rows to which the action is to be applied.

The Locale is used when validating Date, Time, DateTime, Decimal, Percent, and Price data values. For example, when Locale is en-US, date values must be entered in MM/DD/YYYY format. When Locale is en-GB, date values must be entered in DD/MM/YYYY format.

When you wish to invoke an action on two or more rows, it is more efficient to invoke the action on all of the rows in a single API call than to invoke the action on each row in a separate API call. 

See Use templates in an automation for more on creating webhook body templates.

The following provides an example of the request body.
