Impacts of validation error on buyer and store owner

  • Impact of PayPal IPN validation error on you (as a store owner)

Suppose WooCommerce gives the payment as “on hold”. But still, the buyer successfully places and pays for the order. The store owner will also receive the payment on the PayPal account.

PayPal Balance check

But because of IP issues or differences in the primary email and receiver’s email, it will raise PayPal IPN error. It will further place this order on hold.

To fix this, you must change the order status manually from the dashboard of WooCommerce as completed.

  • Impact of PayPal IPN Response errors on buyers/ customers

So, whenever WooCommerce puts a hold on the order, the buyer will never receive any confirmation email.

Let’s take a scenario. For instance, the store owner will receive the payment. The buyer will not receive notifications about payment completion.

Here, the buyer has to notify about the payment issue. He/ she has to send the proof for payment compilation. The store owner needs to clarify the payment and has to place the order manually.
