IPN Callback Function Not Being Called

Hi Noor,

I’m using the IPN callback function to do post-transaction operations like updating the database, sending emails etc. but looks like the function is not getting called at all.

I have the IPN callback on functions.php

function my_callback_function($ipn_response) {
   // do stuff
}
add_action('wp_paypal_ipn_processed', 'my_callback_function');

– I don’t see any errors on the server error_log
– Transaction is updated on the WP PayPal dashboard and no errors reported on the debug
– I also used the IPN Simulator on PayPal to send to https://mydomain.com/?wp_paypal_ipn=1 and it was successful
– WordPress v5.5.3 and WP PayPal v1.2.2.5

Any pointers is greatly appreciated.

Thanks in advanced!
