You can significantly expand Dashly's capabilities using Google Sheets and Google Apps Script.
For example, you could record Dashly ID of each user who made an order, or set a promocode for each particular user, all using the spreadsheet. In addition, you can use data from your sheets in triggered messages, say, pop-ups.
Here's an example of using the data in a pop-up.
1. Create a new table or open the one you already have. We'll be using the table with some information about the products as an example.

2. Go to Extensions -- Apps Script. You'll be redirected to a new page containing three script lines.

3. Delete the lines and instead paste the following script:
function getData(){
try{
var values = SpreadsheetApp.openById('ХХХ').getSheetByName('YYY').getDataRange().getValues();
return values;
}catch(e){
return [[e.message], ['U SENT ' + JSON.stringify(parameters)]];
}
}
function doGet(e){
var cs = ContentService.createTextOutput();
cs.setMimeType(ContentService.MimeType.JSON);
cs.setContent(JSON.stringify(getData()));
return cs;
}
Instead of XXX, insert the table ID.

Instead of YYY, insert the name of the table sheet containing the data, for example, Sheet 1.
Using a GET request, you can return the data from the sheet with the help of the inserted script.
4. Click Deploy- New deployment. Select "Web app" as a new deplayment type. Set the project's name, set access for Anyone. Then click Deploy.

You will then get a Web app link, save it for later:
5. Let's move on to editing the pop-up. Suppose the block with products contains the following:
<div class="dashly-custom-carts">
{% for b in massViewed[:3] %}
{% set link = b.props["$url"] %}
{% set img = b.props["$img"] %}
{% set price = b.props["$amount"] %}
{% set name = b.props["$name"] %}
<div class="dashly-custom-cart">
<div class="dashly-custom-item-img">
<a href="{{link}}" target="_top" title="{{name}}"><img src="{{img}}" alt="{{name}}"></a>
</div>
<div class="wrapper">
<div class="dashly-custom-item-name">
<p><a href="{{link}}" target="_top">{{name}}</a></p>
</div>
<div class="dashly-custom-item-price">
<p>{{price}} р.</p>
</div>
<div class="dashly-custom-item-href">
<a target="_top" href="{{link}}">More</a>
</div>
</div>
</div>
{% endfor %}
</div>6. You'll need a function to execute an ajax request using the GET method and substitute the data received in response (the products) into the block with products.
This is what you should get:
function get_discount() {
$.ajax({
url: 'ZZZ',
type: 'GET'
})
.done(function(data) {
$('.dashly-custom-cart').each(function(index, el) {
for (var i = 0; i < $(data).length; i++) {
$(el).after('<div class="dashly-custom-cart"> <div class="dashly-custom-item-img"> <a href="' + data[i][1] + '" target="_top" title="' + data[i][0] + '"><img src="' + data[i][3] + '" alt="' + data[i][0] + '"></a> </div> <div class="wrapper"> <div class="dashly-custom-item-name"> <p><a href="' + data[i][1] + '" target="_top">' + data[i][0] + '</a></p> </div> <div class="dashly-custom-item-price"> <p>' + data[i][2] + ' р.</p> </div> <div class="dashly-custom-item-href"> <a target="_top" href="' + data[i][1] + '">More</a> </div> </div> </div>')
}
});
})
};
get_discount();Instead of ZZZ, place your web app URL. Paste this code into the pop-up and finish creating the message.
