Setting up Google Checkout
Using Google Checkout is really easy with Cart45. You need to have a few things in place first and then perform a few tasks which should take about 10 minutes:
- Get a merchant bank account
- Get a Google Checkout account
- Configure Cart45 with your Google Checkout settings
- Configure Google Checkout with your Cart45 settings
1. Get a merchant bank account
In order to take payments online, you must have a merchant account with a bank. All payment providers lke Paypal, Protx, Worldpay and Google Checkout make this a mandatory requirement. We can't help you with this step and we advise that you speak to someone at your bank for advice.
2. Get a Google Checkout account
If you don't yet have your merchant account you can still set up Google Checkout (you just won't be able to take any payments - yet.) Head to https://checkout.google.com/sell/ and click the Sign up button then follow the instructions on screen.
3. Configure Cart45 with your Google Checkout settings
Once your Google Checkout account is set up, log into it and from the main page (the first page you see after logging in to Google Checkout) click the 'Settings' tab towards the top. Then click the 'Integration' link on the left.
You should now see something like this
On the right hand side is your Google merchant id and Google merchant key - make a note of them.
Open a new tab or window in your browser and head over to your Cart45 website's admin area - which should look like this www.yoursitename.com/admin.Where www.yoursitename.com is your website address.
Once logged-in to Cart45 click the 'Settings' tab.
This should load website settings and if you scroll down you'll see two fields: one for the Google merchant id and one for the Google merchant key. Simply enter the relevant codes into those two fields.
4. Configure Google Checkout with your Cart45 settings
In order for Google Checkout to 'inform' Cart45 of sales you need to tell Google Checkout which page to talk to. Hopefully you left Google Checkout open in another window or tab if so go back to it and on the same screen you were on before (login > Settings > Integration) make sure the form field labelled API callback URL: has a value like this:
https://www.yoursitename.com/inc/google-checkout/responsehandler.php
Where yoursitename is repalced with your web address so if you website is www.bobsautoparts.com you'd have:
https://www.bobsautoparts.com/inc/google-checkout/responsehandler.php
Other options
- Check My company will only post digitally signed carts
- Set Callback method to XML
- Under advanced settings make sure all checkboxes are checked
