Paypal Pro Setup Instructions

I have everything setup and I am getting Payment failure

This transaction cannot be processed due to an invalid merchant configuration.

On the Paypal side I did this:
1. Setup to use a 3rd party with paypal built in
2. Obtained API Signature.
3. Entered them into the Paypal Pro extension.
4. Get error mentioned above.

Hello,
As we answered you in the Pre-Sales questions category, PayPal Pro only supports 3 countries: United States, United Kingdom and Canada. Can you let me know what's your country?
If PayPal Pro does not work with your country so you can not use it. In this case, we will refund the money to you.
Hope to hear back from you soon.
Sincerely, Giang

I am in the United States. I went through the upgrade process on PayPal to the Business level, obtained the API's, entered them in the PayPal Pro extension setup and get the error.

I've read all the threads on the forums looking for answers.

Hi there -- I have also just purchased the Paypal Pro extension and am getting the same error message mentioned above.

I entered my username/password and API Signature in the Paypal Pro extension screen but get the error message.

I also tried requesting a new API Signature from Paypal and re-entering into the extension but same error.

(it is set to Live mode)

Any suggestions? There does not seem to be any configuration options on Paypal side, they only give user/pass/signature and that's it.

Hello Trevor,

The problem comes from your PayPal account. If you have another PayPal account, please try to use it if it works or not. By the way, PayPal Pro only supports 3 countries: United States, United Kingdom and Canada. What's your country?

I just replied you via Ticket System too. Please following up there to get the supports.
