In my paypal preferences for IPN, there's a spot for a Notification URL, is this something that ModularMerchant Uses?

Right now, it looks like IPN is not enabled for my account, but most orders work anyway. However about 1 in 4 orders doesn't come back to the store and I have to manually generate the download receipt.

Yes, the Notification URL is built-in to the pre-made PayPal forms provided by Modular Merchant as a hidden form field titled "notify_url".

For example, using the {COMPOSITE-PAYPAL-BUTTON} or {FIELD-REQUIRED-PAYPAL-FIELDS} QuickCode Tags in your HTML template will build a "Pay with PayPal" form. The contents of this form will look something like this:

<form action="https://www.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="business" value="email address" />
<input type="hidden" name="currency_code" value="store's currency type" />
<input type="hidden" name="cmd" value="_cart" />
<input type="hidden" name="submit_paypal_standard" value="1215621678" />
<input type="hidden" name="upload" value="1" />
<input type="hidden" name="item_name_1" value="product name" />
<input type="hidden" name="item_number_1" value="product SKU" />
<input type="hidden" name="amount_1" value="product price" />
<input type="hidden" name="handling_cart" value="shipping fees" />
<input type="hidden" name="tax_cart" value="taxes" />
<input type="hidden" name="bn" value="ModularMerchant.MarketplaceSTANDARD" />
<input type="hidden" name="return" value="URL of your store's "return" page" />
<input type="hidden" name="cancel_return" value="URL of your store's "cancel" page" />
<input type="hidden" name="notify_url" value="URL of your store's "notify" page" />
<input type="hidden" name="custom" value="order tracking data" />
<input type="image" name="pay_with_paypal" src="https://www.paypal.com/en_US/i/btn/btn_xpressCheckoutsm.gif" />
</form>

All of the items in blue above are generated automatically by the shopping cart software when the QuickCode Tags listed above are used. I believe that including the "Notificaiton URL" within the form submitted to PayPal circumvents the need to enter one within the PayPal account area. However, you could always try pasting a copy of the "notify_url" URL generated by your store's PayPal form into that field in your PayPal account area.

PayPal service issues can cause their website to fail to send the order data back to the store's Notification URL, which will unfortunately prevent the order from being listed in your shopping cart records. More info on PayPal service issues can be found on their website at: http://www.pdncommunity.com/pdn/blog?blog.id=mts_updates
