    Begining to find the lack of communication bewildering.

    The one time DrB replied you got the issue the wrong way round.

    I've made it clear I will work with you to solve the problem by providing full logs of the issue once I know a resolution is being worked towards.

    Hi @DrByte
    I have two sites for the same client one runs Zencart 1.5.6a and the other 1.5.6c both run on a server running PHP 7 and recently switched to using PayPal Express with Payflow-UK. Both sites offer either payment by CC/DC and PAYPAL if the customer selects CC payment goes through without any issues . But if they opt for PayPal they get the "An error occurred when we tried to contact the payment processor. Please try agin , select an alternative payment method, or contact the store owner for assistance. (4) 4 Invalid Amount - Invalid Amount"

    Can anyone throw some light on this please, thank you.

    If you enable logging for the module, what's in the PayPal-CURL-xxxxx.log file generated by the transaction attempt? The actual details being transmitted should appear there. What's the amount of the transaction?

    Is it just something with a comma as a thousands-separator?

    The strange thing is if I change the option to PayPal and not Payflow-UK in admin express checkout the problem does not occur. Dr Byte for your info when the client applied to Paypal for pro, PayPal had to give them a special link for the option for Payflow-UK as it did not appear in their account. I spoke with PayPal and they have changed or are going to change something. I have emailed PayPal but still awaiting a reply from them!
    Thanks for your help.

    I'm wondering:
    - Is it because the amount is so low? ie: under 1.00 when the tax portion is separated out for PayPal's calculations?
    - How is the log different when using "PayPal" vs "Payflow-UK"?

    The Test purchase of 1.00 is not an issue when the Payflow-UK has been changed to PayPal. The amount of purchase does not seem to matter as some purchases produced the warning that were 50 plus, customers where unable to complete the purchase. CC payments go through OK . It's only when the customers opts to pay via PayPal express, and we have set express to use Payflow-UK that we get a problem.

    When using PayPal no log is generated as far as I can see, apart from the usual in admin/orders details.

    Just as a side issue, as I understand it Cardinal Commerce has an agreement with PayPal and all you need to do is register, the link that PayPal sent no longer works. Are you aware of a link that allows Zencart users to register with Cardinal Commerce?

    Thanks

    @DrByte
    Something has changed at PayPal. We have contacted PayPal and they are looking into why the Cardinal Commerce process is not working . Because the link that PayPal provided no longer works (same link on zen cart documents). The client contacted Cardinal Commerce with the following reply:"Basically you will need to go back to PayPal as they currently do not have an EMV 3D Secure solution in place." Paypal support has been emailed with this information, and we await a reply.
    So we have stopped using the Payflow-uk option in Zencart and currently use Paypal option. This works for customer paying via PayPal express or PayPal, no logs appear.
    However, if the CC version of payment is used the payment goes through but an email is generated saying "Cardinal Lookup 3[nn2ej6m516kr6sf8hf420ta7h9] Cardinal Centinel - cmpi_lookup error - 1002, 2002, 2020 - Error Processing Lookup Request Message, Invalid Merchant Id or Processor Id, Invalid Transaction Password

    There are 3 steps to configuring your Cardinal 3D-Secure service properly:
    1-Login to the Cardinal Merchant Admin URL supplied in your welcome package (NOT the test URL), and accept the license agreement.
    2-Set a transaction password.
    3-Copy your Cardinal Merchant ID and Cardinal Transaction Password into your ZC PayPal module. etc"

    My question is how can I disable the cardinal merchant aspect, is it really necessary in the UK as PayPal UK as I understand it are registered as a bank and would apply their own 2 part authentication or have I got this wrong?

    Further information from Cardinal Commerce:
    "At this time in 2021 we are referring PayPal Pro merchants back to PayPal for boarding on Complete Payments. We have been working on cleaning up the merchant messaging to minimize confusion but realize there is still some confusion out there. We were not able to enable 3DS 2.1 in a timely fashion for the UK merchants whom will need to support this protocol for issuers impacted by PSD2 mandates."
