This method assumes that the UOE (Unified Order Entry) password is active for your store. Note that this will change the payment information for all subscriptions associated with this customer.
- Go to your Advanced Settings in the FoxyCart admin for your store.
- Copy the password from the "unified order entry password:" text box.
- Head over to subscriptions, still in your FoxyCart admin.
- Find the subscription you're trying to update payment for and click "Edit".
- Scroll until you see "Direct To Checkout" and click the link directly below the introductory text. This will show you the checkout as the customer would see it.
- Go ahead and paste in the password that you copied from UOE settings.
- You should now be able to update the customer's info.
- Click "Update My Subscription" to save the new information.
