1 click upsell with clickbank and paydotcom?

I came across Warrior Forum "Special Offer" section and found out that there's a WSO titled "1clickupgrade software" by patricchan

The 1click software claim that it works with Paypal, 2Checkout, Clickbank, Paydotcom and etc.

After my own testing on the lite version, it was a different 1 click upsell.

I have been searching the 1click upsell that allow me to charge my customer without them to enter their credit card again after making the first purchase. I have found ipowerpay.com but it only for US people.

I was wondering if someone in the forum not from US but able to work with 1click upsell like 1shoppingcart or authorize.net?

I know Clickbank work with 1click upsell but it's not easy to get approval. The requirements are too high.

Info from Clickbank webpage

This capability is available to vendors who meet specific sales, refund, and chargeback rates, as well as other constraints:

• ClickBank client for a minimum of six months
• Made over 5000 sales through ClickBank
• Lifetime chargeback rate must be 0.6% or lower
• Lifetime refund rate must be 10% or lower
• Maximum price of each upsell product must be $500 or less
• Product cannot be physical or a recurring billing product

In addition, a vendor's upsell flow must be approved by ClickBank.

By the way, the 1clickupgrade software is for upselling "before checkout" instead of "after checkout". :-)
