# Integrating the verification stage

> Embed the ABBYY FlexiCapture Web Verification Station in a third-party system via an iframe, passing project, role, stage, task, and language URL parameters.

The instructions provided in this section assume that Windows authentication is used. Alternatively, you can use FlexiCapture or SAML authentication.

To load the Verification Station GUI and functionality into the `<iframe>` element, set the `src` attribute to:

```
<stationUrl>/WinAuth/Verify?projectId=[project identifier]&roleId=[role identifier]&stageId=[stage identifier]&disableSendToStage=false&hideTaskInfo=false&disableChangeDefinition=false&taskId=[task identifier]&loadInColor=true&returnTo=DeadEnd&mode=mini&language=en-Us
```

Users will interact with the integrated Verification Station in the same manner they interact with non-integrated Verification Stations in the standard processing scenario. A customized menu is used for forwarding tasks to the next stage and for exiting the integrated Verification Station.

You can set up the integrated Verification Station by editing the keys in the `<appSettings>` section of the `Web.config` file. To disable a menu item, set the corresponding key to `true`:

* `DisableSendToRescan` – sends a task to the Re-scanning stage
* `DisableTaskPostponement` – postpones a task
* `DisableSendToStage` – sends a task to a specific stage
* `DisableSendToExceptions` – sends a task to Exceptions

We recommend disabling the display of the Verification Station header and footer. This will ensure that the user can only access a specific batch and will not see the program features unrelated to the task at hand. This can be achieved by adding the suffix `?mode=mini` to the URL or by setting the `Headless` key to `true`.

When the user finishes processing the task and exits the integrated Verification Station, the `postMessage` method is used to pass one of the following messages to the parent element:

* `FC_Verification_TaskClosed` – The task was closed and sent to the Export stage.
* `FC_Verification_TaskSentToStage` – The task was sent to another stage.
* `FC_Verification_TaskSentToExceptions` – The task was sent to Exceptions.
* `FC_Verification_TaskPostponed` – The task was postponed.
* `FC_Verification_TaskSentToRescan` – The task was sent to the Re-scanning stage.
* `FC_Verification_CantGetTask` – The program failed to get the task for some reason.
* `FC_Verification_TaskRejected` – The task was rejected.

## Sample code for receiving a message from the parent element

```javascript theme={null}
window.addEventListener("message", receiveMessage, false);

function receiveMessage(event) {
  alert("Received event: " + event.data);
}
```

Once the message from the `<iframe>` element is processed, the integrated Verification Station can be closed down so that the user can resume his/her work with the third-party system.
