As part of your registration flow settings, Checkout & Registration Manager allows you to set custom Post-Registration and Cancel Registration URLs.
Post-Registration URL
If entered, the Post-Registration URL replaces the URL used for the "Keep Shopping" button on the registration confirmation page:

Figure 1. The Post-Registration URL takes place of the "Keep Shopping" link on the registration confirmation page.
If you do not enter a custom Post-Registration URL, clicking the "Keep Shopping" button on the registration confirmation page will return a customer to the page from which they accessed the registration flow.
If you've chosen to set a Post-Registration URL for which it does not make sense to use the button label "Keep Shopping," you may customize the text label used for the "Keep Shopping" button on the registration confirmation page. Learn how.
Cancel Registration URL
Using the Cancel Registration URL field, you can specify a page to take a customer to when they click the "Cancel" button on their registration form before completing the form and submitting it.
If you do not enter a custom Cancel Registration URL, upon clicking the "Cancel" button on the registration form, a customer will be taken back to the store page from which they accessed the registration flow. If a customer accesses the registration flow from the checkout options page and clicks the "Cancel" button on the registration form, they will be returned to the checkout options page.
