Closing the Webview

It's a good idea to close the webview after a transaction is complete, especially if actions the user took will result in a message in the thread.

There are two ways to do this:

Messenger Extensions
Redirect URL

Closing via Messenger Extensions

MessengerExtensions.requestCloseBrowser() will close the webview. You may want to do this after a transaction or flow is completed.

<script>
      MessengerExtensions.requestCloseBrowser(function success() {
  
      }, function error(err) {
  
      });
</script>

Params

Param	Description	Type	Required
success callback	This function will be called if `requestCloseBrowser` is successful.	function	Yes
error callback	This function will be called if there is an error.	function	Yes

Closing via Redirect

You can also redirect the user to a URL with the following format:

https://www.messenger.com/closeWindow/?image_url=IMAGE_URL&display_text=DISPLAY_TEXT

The text and image specified as parameters will be displayed briefly until the window closes. This will close only if you redirect from your URL/Page. Direct opening of URL will not close the browser.

This only works on Android. On iOS, the text and image will be displayed, but the browser will not close automatically.

Param	Description	Type	Required
`image_url`	Image to be displayed before closing. Image is rendered with width 72px and height 72px.	string	Yes
`display_text`	Text to be displayed before closing	string	Yes
