How can I update the Stripe charge description with the gclid parameter in GiveWP donations?

It looks like the filter you’re using (give_payment_gateway_donation_summary) isn’t actually the one that sets the description on the Stripe Charge. Instead, the donation summary may be used for display on your site only. To pass a custom description to Stripe, you need to adjust the parameters sent in the API call that creates the charge.

For GiveWP using Stripe, you can use the filter that modifies the Stripe charge data. For example, try hooking into give_stripe_charge_data like this:

PHPCopied
function custom_stripe_charge_description( $charge_data ) {
    if ( isset( $_GET['gclid'] ) && !empty( $_GET['gclid'] ) ) {
        $gclid = sanitize_text_field( $_GET['gclid'] );
        $charge_data['description'] = "Petit Magicien Conversion GAds | gclid=" . $gclid;
    }
    return $charge_data;
}
add_filter( 'give_stripe_charge_data', 'custom_stripe_charge_description' );

This filter modifies the array of data that will be sent to Stripe when creating the charge. Make sure that:

• The filter name is correct for your version of GiveWP/Stripe integration.
• There aren’t any caching issues or other overrides modifying the charge data later in the process.

Using the above approach should ensure that the description you send to Stripe is updated with the gclid parameter from the URL.
