If you're using the Classic builder, you can find that article here.
All typeforms finish with an Ending, which appears after respondents click submit. You can customize Endings if you have an Essentials or higher account.
If you have a Free account, your typeforms have a default, branded Ending that looks like this (colors vary depending on your theme or design):
When you upgrade your account, your default Ending screen will be different:

Note! Endings will not appear to your respondents if you are using Redirect upon completion, as this feature will skip them.
Show different Endings based on score
Make your typeforms even more dynamic: use Calculations and Logic to show people different Ending screens depending on their answers. Here’s how.
How to add and use a customized Ending screen.
1. Open your typeform from your Workspace.
2. You can find the Ending screens under Endings. Click an Ending to edit it or + to create a new one:
3. Now you can write your Ending text. Hover over the question and click Ending to open question settings (explained below), or Layout to add an image and so on.

Tips! Remember, you can put URLs in your text, and they will be automatically clickable. However, we don’t support HTML tags for hyperlinking.

Recall Information
Click @ to include information (answers, scores, price or Hidden Fields) from your typeform. This is useful for showing respondents their answers, or perhaps including their name, if you have collected that in your typeform.
Layout images
Add a layout image to your Ending screen. Click the Layout button, and select Edit under the Media section.
Now you’ll be able to choose an image from the Unsplash library, add an icon from the Noun Project or upload or drop your own image file.
You can upload JPEG, PNG, static or animated GIFs. The maximum width for an Ending image is 800px – larger images will be automatically resized down to this width.
You can also crop and adjust your image, add filters to it and change its colors:
Once uploaded, you’ll see what your Ending screen will look like directly in the editor.
To remove your image click Layout and select the option without an image, as seen below:
To change your image, follow the same steps as when adding a new image by selecting Edit under Media.
Video
You can include a video, from YouTube or Vimeo or search the Pexels library. Simply click the Video tab in the media editor, and paste in the URL of your video.

Tips! You can use a video or an image, but not both. If you’ve added an image, you must remove it before trying to add a video!
Button
By default, your Ending screen has a button that will restart your typeform.
You can toggle this on and off, and also change the text of the button here.
Redirect to URL
By default, the Screen button reloads your typeform, as explained above. But you can change this to link to any URL you like. So if you want respondents to visit your site after completing the typeform, just add the link here.
Remember: if you want to redirect users to your URL before the Ending screen, you need a Professional account, which gives you Redirect on completion.

Note! Your URL must be a secure HTTPS address – make sure this is included in your URL or the redirect will not function.
Share icons
Use this to toggle the social share buttons. These allow your respondents to share your typeform quickly on Facebook, Twitter and LinkedIn.
