# Submit Action

> Use the Submit Action activity to complete and return a result for an App action or task in an Action Center workflow.

## Description

Use the Submit Action activity to complete and return a result for an App action or task in an Action Center workflow.

This activity becomes available when you select **Define workflow file** in the **Events** tab of a control in your Action app.

The Submit Action activity works as follows:

1. The activity submits the outcome of an Action Center task to the parent process that created the task using the [Create App Task](https://docs.uipath.com/activities/other/latest/workflow/create-user-action) activity.
2. That same process waits for the outcome using the [Wait for App Task and Resume](https://docs.uipath.com/activities/other/latest/workflow/wait-for-user-action-and-resume) activity.
3. Once the outcome is submitted, the parent process resumes from where it left off. For more information on App tasks, refer to [Working with App tasks](https://docs.uipath.com/activities/other/latest/workflow/woking-with-app-tasks).

## Properties

* **Outcome**: The outcomes of the user action, defined in the action schema. Examples for user action outcomes are the following:
  + **Approve**: You can approve a submitted form.
  + **Reject**: You can reject an invoice after review.
* **Properties override**: You can override output and input/output properties defined in the action schema when submitting the task.
  
To override a property, follow these steps:
1. Select **Add Properties Override** in the activity. The user-specified action properties defined in the action schema are displayed.
2. Select the property you want to override.
    :::note
    You can override only output and input/output properties.
    :::
3. Select **Update Fields**.

4. Bind the property to the value of an app input control.

Use the following expression to bind app control values to action properties: `<Controls>.<MainPageName>.<InputControlName>.value`

For example, to override a property like `Reviewer Comment` with the value from a comment field in the app, use: `Controls.SimpleApproval.ReviewerComment.Value`.

       :::important
       * If you rename a property after adding it to the
       override list, the override is removed. You must re-add it using **Add Properties Override**.
       * The **Submit Action** activity returns
       default values for all output or input/output properties that are not overridden.
