# Purchase

When the purchase success page is loaded (thankyou.html), fire the following scriptlet to capture the purchase information

```
window._mp.safeExecute('evPurchase', function() {

   /**
    * if user does not have first name and last name, split the name using space
    * and assign first half to fName and second to lName
    *
    *
    * Example:
    * var userName = 'full name';
    * var fName = '';
    * var lName = '';
    * 
    * if (userName.indexOf(' ') > -1) {
    *   fName = userName.split(' ')[0];
    *   lName = userName.split(' ')[1]; 
    * } else {
    *   fName = userName;
    *   lName = undefined;
    * }
   */

   eedl('user_info', {
      pid: '<unique identifier representing user>',
      email: '<email address of user>',
      phone: '<phone number of user - no country code>',
      country: '<country code only>',
      city: '<city - madurai>',
      state: '<state - Tamil Nadu>',
      fName: '<first name of user>',
      lName: '<last name of user>',
      zip: '<zip code>',
   });

   eedl('mp_purchase', {
      currency: 'INR', /* Currency of website */
      transaction_id: '<order id - ABC00xxxx>', /* Order Id of transaction */
      cart_id: '<unique cart id>', // mandatory
      value: 123.33, // float value of order
      coupon: '<optional coupon>', // Leave this undefined if there is no coupon
      shipping: 123.33, // total shipping value in float
      payment_type: 'Credit Card', // optional
      tax: 123.33, // total tax value in float
      items: [ // array of items
         {
            item_id: '<mandatory - item_id>',
            item_name: '<mandatory - name of item>',
            item_sku: '<mandatory - style id of item>',
            index: 0, // order of item in array 0,1,2,3...
            price: 123.33, // mandatory - float price - DO NOT MULTIPLY with quantity.
            quantity: 2, // quantity of item
            item_brand: '<optional - brand>', // if not available leave undefined
            item_category: '<optional - category>', // if not available leave undefined
         }
      ],
      ev_source: 'ingestlabs'
    });
  })();
 
```

### Send event from an iframe window

If the event occurs in a iframe window, you need to fire the event using the below script.

```
window.top.postMessage({
      event_name: 'mp_purchase',
      event_payload: {
         currency: 'INR', /* Currency of website */
         transaction_id: '<order id - ABC00xxxx>', /* Order Id of transaction */
         cart_id: '<unique cart id>', // mandatory
         value: 123.33, // float value of order
         coupon: '<optional coupon>', // Leave this undefined if there is no coupon
         shipping: 123.33, // total shipping value in float
         tax: 123.33, // total tax value in float
         items: [ // array of items
            {
               item_id: '<mandatory - item_id>',
               item_name: '<mandatory - name of item>',
               item_sku: '<mandatory - style id of item>',
               index: 0, // order of item in array 0,1,2,3...
               price: 123.33, // mandatory - float price - DO NOT MULTIPLY with quantity.
               quantity: 2, // quantity of item
               item_brand: '<optional - brand>', // if not available leave undefined
               item_category: '<optional - category>', // if not available leave undefined
            }
         ],
         ev_source: '<Orign of the event>' // Example: 1Checkout, Razorpay, Gokwik, etc.
       }
    },
    'PARENT_URL'
);

PARENT_URL is the url of the website.
