Capture applies to Stripe/Braintree integrations. ReCharge users can refer to this documentation for customizing the card update page.

After setting up a new account with Churn Buster, you'll already have default card update forms in place.

These pages are optimized for a great user experience, across mobile and desktop devices, and never require a login before submitting payment info.

Standard and Pro accounts have the option to host the capture page on their own domain. By hosting these pages on your own domain, customers will be linked to, instead of a generic Churn Buster URL.

How to self-host your capture page

You'll need about 10 minutes, and access to your webhost.

  1. From within your dashboard, navigate to your Capture page settings (under Account).
  2. Click the Download Capture link to download the HTML file.
  3. Upload the file to your server. Make it a standalone page — outside of any website templates/styles and without modification to the file contents. Also make sure access to the page won't be blocked behind a login. More specific instructions can be found below.
  4. In Capture settings, indicate the URL where this page can be found (by default it will be
  5. Save your settings.



Testing the Capture page

In Capture settings, you can make adjustments to the style.

  • Note: Capture pages include a tokenized URL to make it unique for each customer

After saving Capture settings, you can test by going to Customers > click into a campaign > click an upcoming email > click Capture link

As customers are linked to this URL, it will display a card update form specific to their customer ID. Updated billing information is securely passed through to your payment processor, and the charge will be reattempted in real-time.

The user will be notified of subsequent payment issues while they are still on-page, prompted to try again with different information.

Once the charge clears... the subscription is brought back into an active state and all is good 👌.

Upload instructions by platform

Ruby on Rails:

Upload the file so that it is located inside of the /public   folder of your application. It should then be visible in your web browser when you visit: 


Upload the file (via FTP in your web host) so that it is located inside of your site's main directory. It should then be visible in your web browser when you visit:


SquareSpace doesn't allow you to host custom HTML files. Please email [email protected], and we can host the page on a subdomain for you.


Upload the file so that it is located in the root folder of your public website. It should then be visible in your web browser when you visit: 


A Note on Security

When links are generated for customers, and included in the emails Churn Buster sends, each link contains a customer-specific ID, as well as an HMAC-SHA signature, signed with both off-site and customer-specific keys. This makes it impossible to guess the URLs of your live Capture pages.
