error message - “Value [addon id] specified for this param is incorrect”
I want my customers to checkout only my recurring addons without a plan.
Solution
Chargebee's checkout pages are plan-specific; meaning, without a plan, it is not possible to purchase only an addon.
Recently, we released (Feb 2021) 'One-time payments checkout'. This feature allows to checkout non-recurring addons alone without a plan.
Note: If you set up a checkout URL for recurring addon, your user will encounter the following error message. “Value [addon id] specified for this param is incorrect”
