PrestaShop: Solve common problems

Solve common problems that may arise, such as those caused by inactive payment methods in your Mollie account.

Restore the connection

Mollie ensures a secure connection to PrestaShop using API keys. Incorrect API keys can cause unprocessed payments, payment methods unavailability, or incorrect payment statuses.

To verify that the API keys are correct, follow the steps given in Connect to Mollie.

Activate payment methods

If a payment method is inactive, or was deactivated in your Mollie Dashboard after you added it to your checkout, it may not appear in PrestaShop or your customer may get errors when trying to pay.

Ensure your chosen payment methods work flawlessly with your e-commerce platform by managing their activation status in your Mollie Dashboard.

To activate payment methods in your Mollie account, follow these steps:

  1. Log in to your Mollie Dashboard.

  2. Go to Settings > Website profiles.

  3. Click Payment methods under the website profile.

  4. Use the toggles to activate your payment methods.

    A blue toggle indicates that the payment method is active. A yellow toggle indicates that it's pending Mollie's approval.

    Important

    Some payment methods require Mollie's approval before they're available in your Mollie Dashboard. If your account has been approved but payment methods are still missing from your dashboard, contact support.

Enable Apple Pay in a one-page checkout

If you use a custom one-page checkout module together with Mollie for PrestaShop, Apple Pay might not work on the checkout page.

To work around this problem, follow these steps:

  1. In your PrestaShop instance, go to PrestaShop/modules/Mollie/mollie.php.

  2. In the mollie.php file, add a custom instanceOf check for your module to the hookActionFrontControllerSetMedia function.
