Hello all,
I am in the process of implementing Google Checkout in an e-store. Once customers click the 'Google Checkout' button, my project requires that they are able to navigate back to the e-store to possibly edit the cart. Customers should be able to click the 'back' button, type in the URL to my cart page, or click the 'edit' link from Google.
At the same time, I need to clear the cart and provide customers with a blank slate as soon as they click the confirmation button on Google's side. I am already listening for a new-order-notification from Google, but this does not always arrive quickly enough to prevent customers from returning to the e-store and scratching theirs heads as to why their carts still show the items they just purchased.
Have any Google Checkout implementors come up with a novel solution to this problem? Any ideas are appreciated!
