I'm working on a website that communicates with a bank API. During the process, the API sends a request to a callback page. I, therefore, created a "callback_bank.php" file, and put it at the root of the drupal folder (along with index.php, cron.php, etc.) so it's accessible by http://www.mywebsite.com/callback_bank.php
How would I go about packaging/deploying that file with the custom module I created, that does the rest of the work ?
Thank you!
Assuming the return path is configurable with the bank, you'd be better to create a hook_menu callback to handle the bank response.
That way you can leverage the Drupal API, e.g access callback to restrict to their IP address range to prevent spoofing etc..
e.g:
/**
* Implements hook_menu().
*/
function MYMODULE_menu() {
$items = array();
$items['payment/callback'] = array(
'title' => 'Payment callback',
'page callback' => 'MYMODULE_payment_callback_handler',
'access callback' => 'MYMODULE_payment_callback_access',
'type' => MENU_CALLBACK,
'file' => 'MYMODULE.pages.inc',
);
return $items;
}
The bank can then request https://www.yoursite.com/payment/callback?param1=foo¶m2=bar
