This is a repost of a project that has not been completed. We need an expert with experience in SSL and Google Checkout to solve problem as soon as possible.
We have a problem with API Callback URL in Google Checkout and Google Checkout Coupon. We have somebody from installed Google checkout level 2 to our site. However, there are problem(s):
1. Google Checkout SOMETIMES fails to process orders (it fails about 50% of the times). The message error is the save as problem number 2
2. When we try to generate coupons, they do not work. (When they checkout via Google Checkout, the box for entering Coupon Code shows up. However, after entering the code, there's a message saying: Your Coupon Code can not be used this time.
We check the Integration in our Google Checkout Account, and find the following error:
We encountered an error trying to access your server at [url removed, login to view] -- the error we got is: [url removed, login to view]: PKIX path validation failed: [url removed, login to view]: basic constraints check failed: pathLenConstraint violated - this cert must be the last cert in the certification path
Also, we don't know what to fill in for API Callback URL, and what Callback method to choose (XML or name/values pair)
1. Our host provider has SSL certificate from COMODO. According to our provider, it is accepted by Google.
2. Unusual events: Google Checkout worked fine for first couple weeks after the installation (by that time, we haven't activate Coupon). When we activated the Coupon within Google Checkout, it did not work (Coupon never worked before), and the problem seems to start. Another unusual event was that our Google Checkout Button was disappeared one day, and we had to fix it ourselves.
We expect that an expert should take a few hours to fix these issues. Please do not bid if you are not familiar with the issue mentioned. Experts who can communicate via Chat are preferred.
Good luck in bidding
If you prefer, you can uninstall our current Google Checkout and reinstall it.
