Hi edhor,
Quoting from the documentation for Sellacious Payment Gateway Development (
See full doc here):
If your plugin requires a redirect and callback mechanism as explained above, you can supply the Callback URL to the gateways as below:
$callbackUrl = $this->getCallbackUrl();
$feedbackUrl = $this->getCallbackUrl(array(), true);
This will return something like (not exactly):
https://yourdomain.com/index.php?option=com_sellacious&task=payment.callback
If you need additional parameters in the callback URL such as “status=success” then call this method as below:
$callbackUrl = $this->getCallbackUrl(array('status' => 'success'));
$feedbackUrl = $this->getCallbackUrl(array('status' => 'success'), true);
You can find this in Page #3 and #6 of the documentation.
Hope this helps. Thanks.
