Please review the following situation that I am referring.
We have following three types of subscriptions in our website:
a) Basic subscription for Four days
b) Premium subscription for one month
c) Other subscription for one year
In our website, we want to provide our customer/user to upgrade from a) Basic subscription to b) Premium subscription
Let’s take an example that the user has subscribed to two subscriptions (a) Basic subscription for four days and (c) Other subscription for one year and he wants to upgrade his Basic subscription (a) to (b) Premium subscription for one month. Now, with the available Modify and html parameters in PayPal for upgrading, if the user is choosing to upgrade, both the subscriptions (a) Basic subscription for Four days and (c) Other subscription for one year are shown in a list in PayPal’s site asking to select one of the subscription to modify.
But, what I need is to show the user only the exact subscription (i.e., (a) Basic subscription for Four days) and not the entire list of all his previous subscriptions in PayPal and ask the user to upgrade to the ‘Premium subscription for one month’.
I just want to know whether this is possible or not. If possible, please suggest how to achieve this.
