See Live Usage Here

When you done with above steps, you can simply use package to connect to Mellat gateway using your credential info supplied by Behpardakht.

Starting Payment

First of all create an instantiate of Mellat class:
$mellat = new HG\Mellat();

Then you should supply some variables and credentials to start payment as below:

All variables are set now. Remember if any of these variables didn't set, you'll encounter an exception before starting payment.

Now all you need to do is starting payment:

Note 1
You should use try-catch block for this plugin as it will through an exception in case of failure.

Note 2
You should catch all exception through AllException type.

Note 3
We can use Language class to translate exception messages as we see above.
You can use it's static function get($index) to get human readable message.
To get more information just look at src/Language.php and it's lang_fa() function to see indexes and messages. Also feel free to change message as you want or try to add extra language to it.

Starting Callback

When payment done or failed in bank side, user will redirect to address you provided before through $mellat->callback.

Now assume that here is a page we consider as callback. First of all we should provide and set some credential limiter than previous:

After these you should call request handler and wait for its response:

Note 4
Same as note 1 to 3, read them carefully.

Note 5
If anything failed you can call $mellat->refund_payment() to return fee to use bank account if his/her balance decreased. Also this is optional and bank will do it automatically after some minutes.
