we are on Civi 5.8 and Wordcpress 5.

A member called and wants to change her credit card information for her recurring membership. I would prefer to send her a link to click so she can change it herself. Does anyone know what the URL is?

Thank you


If they get the email receipts or have the initial email that notifies it is recurring it has the URL.

This is what I see for WP:


crid is the in the civicrm_contribution_recur table

Not sure what CS string is.

    CS is a checksum, which in this usage means the link is only valid for a certain time (for security reasons). After that time you need to give a new link with a new checksum.

    Actually for "updatebilling" that particular checksum might have infinite lifetime, so it's just a secondary access check, to prevent random people from updating anyone's billing info. But it's still based on a timestamp of when the link was generated, so isn't a fixed string.
