How can I resolve the error "Sorry the URL OR some of the parameters are not valid"?
The merchant is trying to enable sub-cancellation reason codes, but they are receiving an error "Sorry the URL OR some of the parameters are not valid.".
The merchant is trying to enable the option "Adding a reason code for Subscription Cancellation is mandatory." under Reason codes>>Subscription Cancellation but is receiving an error "Sorry the URL or some of the parameters are not valid.".
Generally, this issue occurs when the settings for canceling subscriptions and adding reason codes are not published under the checkout and self-serve portal configuration.
Go to the checkout and self-serve portal in the UI to see if the cancel sub-setting under the portal is TURNED ON OR OFF.
Also, double-check if the settings are published or not.
If the settings are not published, then publish the settings and try to activate the reason codes. It will work.
