When new member pays through gravity form, 'gform_paypal_post_ipn' hook fires.
It get passed 4 params:
$_POST, $entry, $config, $cancel
I want to retrieve email that user specified on the form, and so far using this code:
$email_field_id = $config['meta']['customer_fields']['email'];
$email_address = $entry[$email_field_id];
Is there more API-ish way to retrieve this info (vs. directly poking into assoc. array?
