How do I connect ZenCart to my merchant account/gateway?

This may be a really elementary question, but I did quite a bit of search in the Tutorial and Forum and could not find the obvious answer.

I am about to get the Merchant Account approved soon. The Service Provider said "integration is really easy". And there are two options: API and "redirected link".

I am currently working with PayPal, and when I set it up I had to enter my "API details, etc" in the Payment Module installation process, to link it to my PayPal account.

But for Credit Card module, I can't find any place to enter any "link information". I tried installing the "cc" module, and turning the various cards on in the Configuration->Credit Cards.

Where should I fill in the missing link?

Thanks !

I am about to get the Merchant Account approved soon.
Who is this merchant account with?(usually a bank)
Does this merchant account support online payments?
What "Gateway Processor" do they support?

Sequence is:

Payment is checked in through one of the gateway processors and processed - they inturn charge the card and deposit funds to your merchant bank account.

The default CC module is specifically for Off-Line payment processing like if you also run a brick & mortar store and have a terminal to process with

The gateway/merchant account provider is Intabill http://intabill.com .

They said they will give me an "integration package" with codes and instructions, etc.

Just getting prepared mentally, what should I do on ZenCart side?

Thank you.

I have never heard of "intabill", but a module for zencart will be required to use this and if one does not exist you are on your own at writing one.

Did you check the "Recommended Services" link at the top of this page as there is a merchant bank/AuthorizeNet package that is economical and is already fully supported in Zen Cart...

I would not mess with an unknown for this critical part of making yourself successful...JMO

Thanks, Kobra. I will take a look at the recommended service providers.

Since I have already gone through the very time-consuming application process with Intabill and my merchant account got approved, I would like to give it a try.

They have a payment module for OScommerce which I attach. Would somebody be kind enough to have a quick look and tell me whether this is something that should work with ZenCart, and if modification is required, to what degree?

I am asking this question because I remember ZenCart's structure is similar to OScommerce's ? I actually do not know what I am talking about.

Also, Intabill says another way is "hosted sales page". If I understand it correctly, I direct the customer to the Intabill hosted sales page (I may have some freedom to customise it), and after the payment is successfully processed, the customer will be automatically redirected to a "payment success/failure url" of my ZenCart.

Does this work? Considering that I am selling downloadable goods and my desired effect is that after payment, the customer should see the "success page" with the download link for the products purchased. And also, how does the total order amount get auto-filled onto this "hosted sales page"? I don't know.

I am quite lost about what I should do. Any help is much appreciated.
