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

I doubt if you can use local host URL
but instead you can create new links, as below
<https://www.instamojo.com/api/1.1/links/>
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.
