# [Zibal](https://zibal.ir) IPG NPM Module

Here is Zibal's NPM Module to Easily Create and Process IPG Transactions.

## Get Started
1. Install Module using `npm` or `yarn`
    ```
    npm install zibal --save
    ```
2. Configure Module 

    ```javascript
    const Zibal = require("zibal");
    
    
    const zibal = new Zibal({
        merchant: "YOUR_MERCHANT", // Your IPG's Merchant Id (You Can Get it From Zibal's Dashboard)
        callbackUrl: "https://yourwebsite.com/ipg/cb" // The URL Where User will be Redirected to After Payment
    })
    ```
    
    You can Configure These Two Parameters for Each Transaction Too.
    
    You can Specify `merchant: zibal` to Perform Sandbox Transactions.

3. Create IPG Transaction
    ```javascript
    zibal.request({
        amount: 200000, // Required - In Rials
        orderId: "ZBL-aaaa", // Optional
        merchant: "YOUR_MERCHANT", // As Said Above, You can Specify merchant for Each Transaction too.
        callbackUrl: "https://yourwebsite.com/ipg/cb", // As Said Above, You can Specify merchant for Each Transaction too.
        mobile: "09123456789", // Optional - User's Card Numbers will Show inf Dropdown in Shaparak Page if you Send User's Mobile
        description: "THIS IS MY DESCRIPTION", // Optional
        allowedCards: ["5022291092719457"], // Optional - Any Transaction with a Card Number which is not Present in this Array will be Unsuccessful
        linkToPay: true, // Optional - If true, we will generate a Short Link for this transaction.
        sms: true, // Optional - If true, we will Send the Short Link to User's Mobile
    }).then(response => {
        
        // Redirect User to Payment URL after Creating Transaction
        // res.redirect is for Express Framework
        // Store response.trackId Somewhere too
        res.redirect(response.paymentUrl);
    })
    ```
    
    See [Documentation](https://docs.zibal.ir/IPG/API) For More Features.
    
4. Catch Data in Callback
    
    User will be Redirected to `callbackUrl` you Have Sent in Request. We Will Specify Transaction Information in Query Strings Link:
    
    `https://yourwebsite.com/ipg/cb?trackId=10000&success=1&status=2&orderId=1`
    
    You Shall Catch it in Your Application (ExpressJS, Koa, Hapi, Loopback, Sails, Meteor etc.) and Verify the Transactions if `success === true && status === 2` and Process Your Order for your Customer.
    
5. Verify Transaction
    
    Here you Should Tell Us that You Got the Transaction Information & Verify it.
    
    ```javascript
    zibal.verify({
        trackId: 100000, // Required - Transaction's trackId Which we Specify in callback.
        merchant: "YOUR_MERCHANT", // As Said Above, You can Specify merchant for Each Transaction too.
    }).then(response => {
        // ALL SET AND DONE
    })
    ```

6. Done
