Good day @kk-xiyan,
Thank you for posting to the PayPal community.
We apologize for any inconvenience.
Upon reviewing the error details, it appears that the reported order attempts failed to capture due to an error "INSTRUMENT_DECLINED".
Guide link to resolve the issue - https://developer.paypal.com/api/rest/reference/orders/v2/errors/#link-captureorder
UNPROCESSABLE_ENTITY, this error usually occurs when the API request payload is invalid or not well-formatted or the merchant account is restricted.
Also, please ensure that the API requests are in the correct format. Here is a sample for your reference:
{
"intent": "CAPTURE",
"purchase_units": [
{
"amount": {
"currency_code": "USD",
"value": "100.00"
}
}
]
}
For more detailed information, please refer to the guide provided in the following link:
https://developer.paypal.com/docs/api/orders/v2/
https://developer.paypal.com/docs/api/orders/v2/#orders_create!path=purchase_units&t=request
Unfortunately, we are restricted to process live payments on merchant’s website. Can you please try to process a test payment via card which is not linked to your PayPal account.
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.
