My payment system through PayPal has suddenly stopped working.

OpenCart ecommerce store. 2.0.3.1

My payment system through PayPal has suddenly stopped working for no apparent reason. No changes were made by me. All my customers after entering their credit card details get the message "Please wait". After this nothing happens. All stages up to the final confirmation of payment work fine.

Good day @kilbaha 

Thank you for posting to the PayPal community.

Third party eCommerce develops their own modules/plugins.

I would suggest to please contact your website developer or the third party eCommerce support to verify the integration code. It is important to cross check whether you are using the same SANDBOX/LIVE  REST API Credentials(Client ID & Secret) while performing the below API calls.

https://developer.paypal.com/api/rest/postman/ 

Please try to process a test payment using a card that is not associated to your PayPal Account, since merchants can't process self-payments.

If you are still experiencing issues, please create an MTS ticket via the following URL -  https://www.paypal-support.com/s/?language=en_US . Please ensure that you provide detailed information and error details when submitting the ticket.

Sincerely,

Kavya
