wordpress Gravity forms bank account payment

Question

I am trying to make a page with gravityforms to make a transaction with a bank account payment.

I need to send data to iDevAffiliate database.

The response with the support and google searching has led me to just work with this function

add_action( 'gform_post_payment_completed', my_function,  10, 2 );

i don't understand what is this function my_function that probably i need to make on my own and what are these last two parameters 10 and 2 ?

In some examples i find $entry and $action ascotiative arrays that i don't understand how to put data in them.Do they get filled in automatically or i need to fill them in ?

I don't understand anything from the documentation here: https://www.gravityhelp.com/documentation/article/gform_post_payment_completed/

and i found a github example that i don't understand eighter. https://gist.github.com/NikV/7b7ec046df69b1f390bf.

If there is someone that uses these forms or has a working example i would want to see it.Or get a more clear explanation about that function and parameters that i need to pass in.

The add_action call

The add_action call is part of Wordpress, not of the gravityforms component, as you can find here.

The first parameter contains the function to be called (in your case "gform_post_payment_completed").
The second contains the so-called "callback function", a function that is triggered as soon as the first function has been executed completely.
The third parameter is an internal priority flag for Wordpress
the last parameter tells Wordpress how many parameters are going to be transmitted to the initial function, in case of the given function two parameters ($entry and $action) are sent to the initial function.

As soon as the call has finished, the callback function is invoked that could i.e. tells a visitor that the payment has been accepted or to redirect him to a download page or whatever your business case is.

The $entry and $action parameters

The $entry parameter contains all information about the subscription that is currently handled, the entry_info() function may help you understand more about it and here's the documentation for it.

The $action contains information about the currently executed command (i.e. change subscription, execute payment), just search for "$action" on the documentation page for GFPaymentAddon.

I haven't used Gravity Forms but I hope you'll find the necessary details on the documentation pages.

Sending part of the data to an external page via curl

As mentioned before, I haven't used the Gravity Forms component and can't test it, but it should work similar to this:

function gfroms_after_payment_complete( $entry, $action ) {

    // for more info, check https://www.gravityhelp.com/documentation/article/entry-object/

    $orderNo= $entry['id']; // not sure if this would be the order number but it should be a unique payment ID
    $ipAddress= $entry['ip'];
    $amount= $entry['payment_amount'];

    curl_setopt($ch, CURLOPT_URL, "fund.abarila-foundation.org/…Summe:{$amount}&idev_ordernum={$orderNo}&ip_address={$ipAddress}");
}
// Tells the notification to be sent only when this hook is found and to include the arguments ($entry and $action)
add_action( 'gform_post_payment_completed', 'gfroms_after_payment_complete',  10, 2 );
