"Invalid coupon code" from Google Checkout

**tbsmith** · 2 Mar 2008, 08:16 AM

Hi,
I've got the newest ZC and the newest GCO module, and I have commented out the ZC checkout button so that the only checkout method is GCO. Am I still able to use coupons? I've set them up in the Google Checkout Tools window but they never work- I always get the "Invalid coupon code" error.

-Thanks

Hi,
My coupons worked with all http/sandbox, but not https sandbox or production, so I correctly deduced that I had not set up my ssl certificate correctly. I went back over the installation instructions from when I bought my certificate and I had forgotten to uncomment a line in a configuration file somewhere. After that both http and https on sandbox and production started to work.

You have to set the coupon up in the zen cart admin, not in google checkout.

Todd,

I am having similar problem. Could you share which line in your configuration file you commented out?

Thanks a lot,
Jay
