This filter can be used to modify the form submission data before it is used to create the transaction.

This hook has been deprecated. Please use gform_submission_data_pre_process_payment instead.


The filter which would run for all feeds can be used like so:

add_filter( 'gform_authorizenet_form_data', 'your_function_name', 10, 4 );

You can also target a specific form by appending the form id on the end of the hook name like so:

add_filter( 'gform_authorizenet_form_data_4', 'your_function_name', 10, 4 );


  • $form_data Form Data

    An associative array containing the form title, billing address, payment amount, setup fee amount, line items created using the submitted pricing field values and any discounts from coupons.

  • $form

    The form which is currently being processed.

  • $config Config

    The feed which is currently being processed.


1. Change fee_amount

The following example shows how you can change the setup fee depending on the value of a form field.

add_filter( 'gform_authorizenet_form_data', function ( $form_data, $form, $config ) {
    if ( rgpost( 'input_1' ) == 'some value' ) {
        $form_data['fee_amount'] = 0;

    return $form_data;
}, 10, 4 );


Your code snippet should be placed in the functions.php file of your active theme.
