Invalid Form Key Error in Magento After Payment Notification

Invalid Form Key Error in Magento After Payment Notification

Hello everyone,

I'm encountering an issue with my Magento store related to payment notifications. When a payment notification is received from the payment gateway, the request does not include the form_key parameter. As a result, Magento is unable to process the request and redirects to the homepage, displaying an "Invalid Form Key" error.

However, I am unsure how to resolve the missing form_key in the payment notification request. One potential solution could be to disable the form_key check for POST requests coming from specific origins. This way, we can allow the payment notifications to be processed without the form_key parameter.

Has anyone experienced a similar issue or can anyone provide guidance on how to handle this? Any help would be greatly appreciated!

Thank you!
