There are instances where a Paypal transaction can fall into a pending state. Below is a list of common issues associated with pending payments.
To get started, visit this link. Log in to your PayPal account and you will be directed to your IPN history.
Payments may still be pending due to the following reasons:
Address: the attendee did not include a confirmed shipping address, and your Payment Receiving Preferences calls for you to manually accept these payments. You can change this in the Preferences section of your Profile.
Authorization: payment requires manual authorization.
eCheck: the eCheck has not yet cleared. Most eChecks take 5-7 days to clear.
International: your Paypal account is outside the US and you do not have a withdrawal process, which means you have to manually accept the payment in your Account Overview.
Order: the payment action has been set to order and hasn’t been accepted.
Payment Review: Paypal is manually reviewing the payment, most likely due to possible risk or fraud.
Regulatory Review: Paypal is manually reviewing the payment, due to government compliance and regulations. Usually cleared within 3 business days.
Unilateral: the attendee's email address has not been confirmed.
Upgrade: you must upgrade your account to Business or Premier before you can receive the funds, or you have reached the monthly transaction limit.
Verify: your account has not been verified. Check your email (associated with the Paypal account) to complete the verification process.
Other: contact Paypal support for further assistance.
