PayPal Instant Payment Notification Delays
We’ve noticed that PayPal’s instant payment notification (IPN) feature, which AcuInvoice uses to record the receipt of payments, is informing our servers of payments received on a timeframe that can’t really be described as “instant.” There was a post to the PayPal Developer Community blog on Friday indicating that delays were observed. Though PayPal subsequently indicated that the problem had been resolved, it appears as if similar problems may have resurfaced. Therefore, if it takes an unusually long time for PayPal payments to be recorded on your invoices, please understand that this appears to be an issue on the PayPal side. IPN notifications should be received, but it might take several minutes, or even hours for AcuInvoice to be notified.
