I want to implement paypal IPN at my website. For that purpose I created 2 paypal sandbox accounts of type business (seller) and personal (seller) through my paypal developer account. Thereafter I created buy now button at my paypal sandbox business account with item name, code, price etc. and generated a code for buy now button, pasted it on my website. For first 2 weeks testing work smoothly after it started giving errors like
Sorry we cannot complete your purchase at this time. Please return to the merchant and choose other way to pay
Hence again I created 2 separate sandbox accounts, again same problem happened after 2 weeks. What is the reason behind this type of errors and how to rectify it?
This type of error is mainly due to using same credit card or banking account at buyers sandbox account.One need to use different credit card and bank account for too many test transaction performed through sandbox accounts.
