Authorize only on orders over XX amount: LinkPoint

Hi,
When a transaction is proccessed via Credit Card I want to have an Immediate Charge for orders under $250.
If over $250 I want to just Authorize it and process it later after investigation.

I was wondering if this would work and what other files would need to be modified in order to only Authorize CC orders over $250?

In /includes/modules/payment/linkpoint_appi.php on line 402 where it says:
$myorder["ordertype"] = (MODULE_PAYMENT_LINKPOINT_API_AUTHORIZATION_MODE == 'Authorize Only' ? 'PREAUTH': 'SALE');

Add just below it:

if ($chargetotal > 250){
$myorder["ordertype"] = 'PREAUTH';
}

I had a fraudulent transaction for $3100 that occured 5 minutes before Linkpoints auto batch and I was unable to void it. It got through and it took me 3 weeks to clear it up and get my nearly $300 in fees back after I had to make a return as opposed to a void.

Any thoughts or suggestions are appreciated.

Thanks,
Ken

You could try that.

However, you'll need to use $myorder["chargetotal"] instead of $chargetotal

You'll have to do the captures of those authorizations on the linkpoint terminal, not in your Zen Cart, since the options will not show in Zen Cart if the module itself is set to normally do a full charge.
