API error in version 8.0.0 – Unnecessary required billing address fields

    After updating to version 8.0.0 of the Mollie plugin, we’re experiencing an issue during checkout caused by an API error. The payment request returns the following response:
    Error executing API call (422: Unprocessable Entity): The following fields of the billing address are missing: streetAndNumber, postalCode. Documentation: https://docs.mollie.com/reference/v2/payments-api/create-payment

    In this case, the fields streetAndNumber and postalCode of the billingAddress were not included in the request, which is expected behavior. According to the official Mollie API documentation, these fields are not required unless a specific payment method requires them (e.g., Klarna).

    This seems to be a bug introduced in version 8.0.0 of the plugin, where these address fields are incorrectly treated as required, even for standard payment methods. As a result, the checkout process fails.

    Could you please investigate whether this behavior is unintended and possibly fix it in an upcoming release?

    Thank you in advance for your help.

    Hello @thijmens

    To better judge what could be causing this, we are interested in a copy of your WooCommerce system report and your latest Mollie plugin log files.

    The system report can be accessed from here:
    WooCommerce > Status > Get system report > Copy for support

    You can copy the log files from here:
    WooCommerce > Status > Logs > select “mollie-payments-for-woocommerce-[…]”.

    You can share it either via https://privatebin.syde.com/

    Regards,

    Hi there!

    I created an account just for this particular post :-). Sorry for hijacking @thijmens , but I hope this helps you too!

    I am experiencing the same issues with the latest version of the mollie plugin. Before, I was able to generate payment requests for my customers and this did not require an emailaddress or particular address information. Now all of a sudden, it gives me the following entries in the logs:

    2025-03-29T22:39:59+00:00 DEBUG Creating payment object: type Order, first try failed: [2025-03-29T22:39:59+0000] Error executing API call (422: Unprocessable Entity): The ’email’ field is missing.

Field: billingAddress.email

    Same issue here. Payments are suddenly not accepted. With error: “The following fields of the billing address are missing: streetAndNumber, postalCode, city.”

    Reverting to previous version.

    Yep, same issue here with two of our clients. It seems to occur when a checkout is missing some of the default address fields.

    For example, we have a customer who accepts simple payment donations, only asking for an email address and name. This worked fine before, but after the latest update, it’s no longer working. The error log shows that it’s due to the required address fields mentioned above.

    The same issue applies to another customer selling digital products, where no address is needed. The address fields were removed from the checkout, but after the update, the same error appears in the logs, asking for required billing address fields.

    I know we are not supposed to reply with I have the same problem but need to create a new topic according to the forum guide lines… Though I do experience the same problem: payments are not accepted without billing address. Reverting to 7.10.0 resolved the issue.

    Hi Femi,

    Great, thanks.
    I’ve updated the plugin with the provided beta-release from Github and it’s all working as before.

    So it seems to lift the checkout adress-fields restriction indeed and that the issues regarding this topic are fixed in this version.
