I am implementing instamojo payment method into my website. Can I use a localhost URL as Webhook URL in order to test the process?

We can't use localhost or as Webhook URL.If it is used the following error will show "Domain name should not be "localhost" or "127.0.0.1" ". So it must be a live URL.
You cannot use the localhost URL as a webhook URL in order to test the process. But you can simply bypass it, open hosts file from `C:\Windows\System32\Drivers\etc\hosts`
At the end of the line write 

```
127.0.0.1      yourname.com

```

And access localhost using yourname.com.
Just change localhost/your-location url with yourname.com/your-location in the PHP file.
