    That error always means that the credentials are somehow incorrect. You need to double check everything involved.

    1) Make sure Sandbox Mode is not enabled.
    2) Make sure live account credentials are filled into the live account API fields.
    3) Make sure values are indeed accurate with no extra spaces or garbage on either end.

    If you still need more help you should submit a ticket here so that I can work with you more privately.

    @danielaroa9, It sounds like maybe you’ve entered credentials into the “PayPal” settings in WooCommerce, which is what WooCommerce gives you by default.

    Our plugin would add “Express Checkout”, “Payments Pro”, etc.

    You need to make sure you’re filling the proper credentials into the proper settings screens based on which gateways you’re actually processing payments with on your site.
