I am attempting to use the SOAP API to collect credit card payments. When I send a test transaction, I get an error 10548 back, which appears to mean my account is not setup correctly. I already confirmed that I am setup as a business account, I have everything verified on the account, phone numbers added, etc. I contacted support and they seem to be at a loss as to what is causing the issue. Wondering if someone in the community has seen this and has ideas? Thanks

Good day @BBTC,
Thank you for posting to the PayPal community.
If your facing this issue in sandbox test environment, 10548 usually occurs due to the PayPal Sandbox account PRO setup.
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.
Note: Only Business accounts can have Payments Pro enabled. - Click Profile under the email address.
- Click Upgrade to Pro.
- Click Enable.
Once your sandbox business account is upgraded to PRO, you should be able to integrate and perform DoDirectPayment API calls.
If your facing this error 10548 in LIVE production, I request to please contact our PayPal Customer service via link - https://www.paypal.com/smarthelp/contact-us (then choose at the bottom one of the contact methods - email or phone) who should be able to help you regarding your LIVE PayPal account PRO setup query.

I already followed the steps that you suggested. I noticed on the directpayments link that you provided, it says that new users cannot use that feature, and must instead use the advanced credit card payments. Could you provide some clarification on that? I am attempting to use "PayPal PayFlow" on Aruba ClearPass. Thanks
