Google Checkout and Zencart

I don't have much knowledge in programing, but with your easy instructions it was a breeze. This Mod is really a must for any online store in this day and age. When you have customers online, with so much competition - you really have to offer everything you got. Your program delivers what's needed: it integrated with our Zen-Cart very easily, offers real time order status right where you need it and does not interfere with other mods we have installed. Customers trust Google, and now with your Mod they can trust us in their purchase! Your Mod is really a must in any successful online store.

It was a real pleasure working with you. Annoying as I maybe with all my questions that were real simple. Apart from alot of other people I worked with You actually answered every single question and with surprising speed.

Graith Internet have developed a Level 2 integration of Google Checkout for Zencart - the first in the world. You can buy it now. There will be free updates for six months to catch any enhancements or bugfixes and email support is available for any issues you may find.

It's written and tested for zen-cart-v1.3.0.2-full-fileset.zip but it should work with other versions

If you have any questions about it, please use the form below.

The process isn't automatic. You'll be sent an email by a real person and you can converse by email if you have problems or questions.

Level 1 Integration just adds a Google checkout button to your Zencart page. If customers have an account with Google (like they can have a Paypal account), they click the button, login with a click (it remembers your login details) and you see your shopping cart and shipping charges and you can click to confirm purchase.

That's it. The Level 1 module uses shipping modules you configure on your Zencart site but you don't see the order in your Zencart admin panel and it doesn't control stock. You have to adjust that manually.

Level 2 Integration adds communication between Zencart and Google Checkout. It records the order and records the purchase as a Google checkout payment with the GC payment ID. In the administration, you can charge the credit card and you can notify your customer that the order has shipped and it will pass on the information to Google without using the Google Control panel. If the credit card payment was declined, the payment status will reflect this.

This code will look for the email address in members details and automatically make them a member if it's not found. Vouchers work (USA only currently). You can give them shipping discounts or percentage or fixed price off.

Official Google Code The free OSC module developed by Google has been written without the full understanding of how OSC works so the installation instructions are very difficult and the shipping calculations are not done by the OSC shipping modules.

Google Checkout Transaction Charges seem to be much lower than PayPal and the ease of purchase means this is going to be BIG.

PayPal Website Payments Pro charges $20.00 USD monthly fee. The transaction fees are 2.2% to 2.9% + $0.30 USD.

In Google Checkout for every $1 you spend on AdWords, you can process $10 in sales for free. For example, if you spent $1,000 on AdWords last month, this month you can process $10,000 in sales at no cost. The more you spend to promote your business through AdWords, the more you save on transaction processing fees with Google Checkout. This is a nice bonus for big AdWords merchants.

If you exceed your free transaction processing for the month, or you don’t advertise with AdWords at all, you’ll only be charged 2% plus $.20

Note:
Currenly, Google only allows merchants from the United States and UK to register to sell, but they are planning to roll it out to other countries soon.

Your website has to have two bits of software installed called LibXML and CURL. It also needs an HTTPS/SSL connection in order to use Level 2 integration. This zip file contains a PHP page which you can put on your site to see if your website has got this software already installed. test_google_functions.zip (4k)
