    Hi @stk_jj

    Is this in Sandbox mode or live? If you use the Sandbox first, you can get more details about what’s happening in your PayPal sandbox account.

    thanks Corey for your advice.

    I put it in sandbox mode, but error seems not much more detailed to me:

    PayPal error: Security header is not valid (10002)
    A payment error has occurred, looks like chosen payment method is not responding. Please try again later.

    Interesting. That error message might actually help. From this documentation:

    If you get error code 10002 with the message 10002: Security Header Invalid, you have incorrect API credentials. Check that the account that will receive payments was used to generate the API credentials. If you’re using PayPal’s Sandbox environment, you must generate API credentials from within the Sandbox business account rather than a Live account.
