Good day @graffyhost, Thank you for posting to the PayPal community. If your facing this issue in sandbox test environment, this error code - 10548 usually occurs due to the Sandbox PayPal PRO account setup issue. Errorcode : 10548 Shortmessage : "Invalid Configuration" Longmessage : "This transaction cannot be processed. The merchant's account is not able to process transactions." Guide link - https://www.paypal.com/us/smarthelp/article/why-did-i-get-api-error-code-10548-ts1147 Here's how to enable PayPal Payments Pro on a Sandbox test account: Log in to your PayPal Developer account. At the top of the page, click Dashboard. Click Accounts under Sandbox on the left side of the page. Click the email address for the account for which you would like to enable Payments Pro.
