Allow UltraCart To Call The [chargeCreditCard] API

If you do not have the chargeCreditCard API permission turned on, you receive a message like this (body text below):

Subject: UltraCart [UC MerchantID] - PayPal permissions incorrect.

Hi <name of merchant as listed on the user login>,

This automated email is to inform you that your PayPal integration has not been configured properly to allow UltraCart to call the [chargeCreditCard] API.  Please contact support for assistance in adjusting your configuration.

-UltraCart

The solution 

To fix this issue, login to your PayPal account and:

1) Under the My Account menu click on the Profile option.
2) On the left side of the page under My Profile click on My Selling Tools.
3) Click the Update link to the right of API Access.
4) Edit the API access and grant permission for UltraCart to call [chargeCreditCard]

Until you grant permission for UltraCart to call chargeCreditCard, your customers can not use direct credit cards during the checkout.  This is limiting your sales to PayPal only.

UltraCart has received ERROR: 10501

Hi <name>,

UltraCart has received ERROR: 10501 Invalid Configuration This transaction cannot be processed due to an invalid merchant configuration from PayPal.

Make sure that you have accepted the "PayPal Payments Pro" agreement in your PayPal account after you have been approved by PayPal for PayPal Payments Pro. If you have accepted their agreement but are still getting this error, PayPal also occasionally acknowledges the agreement and activates Virtual Terminal but somehow misses activating PayPal Payments Pro itself; if your PayPal "Get Started" summary screen only shows Virtual Terminal and nothing about PayPal Payments Pro, please contact PayPal support to get your PayPal Payments Pro service activated.

If you are only using PayPal Payments Standard with a regular PayPal personal, Business or Premier account (i.e., if you have not upgraded to PayPal Payments Pro), please go to Seller Admin > Payment Preferences and make sure you have PayPal Payments Standard checked (rather than PayPal Payments Pro) and click Submit to save any changes you make.

The solution 

To fix this issue, login to your PayPal account and:

2) On the left side of the page under My Profile click on My Selling Tools.
3) Click the Update link to the right of API Access.
4) Edit the API access and grant permission for UltraCart to call [doCapture]

Until you grant permission for UltraCart to call doCapture, the orders will be stuck in "Payment Status = pending".
