This module allows us to use Instamojo as Payment Gateway in CS-Cart and Multi-Vendor 4.0.x.

• Download the zip file and paste the content of upload folder into your sites main directory, this is public_html is most cases. Note that inside public_html you will already have folders named app and design, so you are supposed to merge the app and design from our module to those folders.

Before we start with the setup I would like you to create a log file to keep track of things, this file will help us in finding issues with the transactions as well as plugin. So, this is a must do thing.

CS-Cart logs everything to "var/log" directory, if you don't have a log directory under var then create one and give it enough permissions so that the plugin can create a file named "imojo.log" under it and write logs to it.

While sharing issues related to plugin do share your "imojo.log" file as well. Our support email id is: support@instamojo.com

• Open the sql_install.txt file and copy its content. Now open phpMyAdmin or which ever MySQL client you are using and run the copied MySQL query. This will add an entry of Instamojo in cscart_payment_processors table.

Now it is time to create a new Payment Gateway backend from Admin backend.

• In Admin backend go to Adminstration -> Payment methods.

• Now click on the + button the top-right side to add a new Payment method, this will open a form.

• In Name field type "Instamojo".
• In Processor dropdown select Instamojo(It's under Gateways section).
• Leave Template as is .
• In Payment category select Credit card.
• In Description you can add some text that will be displayed to users during checkout, for example: "Pay using DB/CC or Online Banking".
• Make sure the Status is set to Active.
• In Icon you can choose the file icon.png received with the zip file.

Currently your form will look like:

Now click on Create to create the Payment method.

Click back on Instamojo payment method we have just created inside Adminstration -> Payment methods and then click on Configure, in some cases due to caching it shows an empty page.

To fix this you will have to clean up the backend cache from "var/cache/templates/backend/", clean up all the files(.php files) from this folder and refresh the Payment method page.

Note that if this form was already there then there's no need to clean the cache.

Here we now have six fields, in the coming sections I will explain from where to get the values for these fields.

In this section we will learn how to create a Payment link along with how to get the required values for Payment Link and Custom Field .

• Create a Payment Link on Instamojo under the Services/Membership option.

  Set the price to Rs. 10 and enable "Pay what you want". Under Title and Description, you may enter something that describes your business and the nature of the products being sold.

  Under Advanced settings of the same link there's a field Custom Redirection URL, here if your website's URL is http://www.example.com then use http://www.example.com/index.php?dispatch=payment_notification.process&payment=instamojo as Custom Redirection URL. This is important because it will be used to register the Payment.

Now click on Get started to save the button.

• Now copy the Payment Link URL and paste this in Payment URL field on the Instamojo module configuration page. URL's format is usually: https://www.instamojo.com/username/slug/.
• Now on the Payment Link page go to More options and click on Custom Fields Create a custom field called Order ID, mark it as required and save it. In the custom field creation page, hover over the field you just created. You'll see a field with the format Field_. Note down the full name (including the Field_ bit. Note that this is case sensitive!).

Enter this name in the Custom field field on the Instamojo module configuration page.

In this section we will learn how to get the values of fields API Key, Auth token and Private salt.

Go the Instamojo developers page, if your are not logged in already then login first and then you'll see the value of API Key, Auth token, Private salt there on the bottom left side of the page.

Simply copy and paste their values in the configuration form in their respective fields.

Now this is the only field we are left with. In this field you are supposed to store the Currency code of currency you're using right now, i.e Indian Rupee or something. If you don't have any such currency in backend then please create one by going to Administration -> Currencies.

For example here I have created a Currency named Indian Rupee with Code "INR", so I am going to use "INR" in the Instamojo configuration form.

Now the form will look like:

Click on Save to save these settings and we are good to go.

Now during checkout you will get an option of Instamojo.
