Why is the request payment method URL link not considering the '=' sign in the email notifications?

Problem Statement

This article explains why the equals sign (=) in the request payment method URL may appear differently in email notifications after saving.

Solution

When you use a URL like https://{site_name}.com/app/settings/billing?update=payment as the goal for the request payment button, Chargebee converts the = into an HTML character code (e.g., =) so it can be used in HTML emails. This follows HTML standards (see W3C HTML spec).

Most email clients send HTML emails by default. Chargebee does the same, so certain characters in the link field are converted to HTML character codes.
