Use the Product object option property in order to define pricing options for dynamic products.

Use case

  1. Add an HTML link or button in your page like the one below.
  2. Create a JavaScript click handler to execute the Inline Client desired methods.
  3. Set the dynamic mode for cart by callingTwoCoInlineCart.setup.setMode('DYNAMIC').
  4. Set your currency using theTwoCoInlineCart.cart.setCurrency('USD')method.
  5. Use theTwoCoInlineCart.products.add({name, quantity, price, options})method to prepare your dynamic products.
  6. The options property should contain a list of objects with the name of the field, it's value and surcharge.
  7. You can see below a signature token request payload for this example. A success response contains a JSON with the property  “signature“ which needs to be used at the next step to set the signature using the TwoCoInlineCart method.
    "merchant": "2COLRNC",
    "dynamic": "1",
    "currency": "USD",
    "products": [
            "name": "A test dynamic product",
            "quantity": 1,
            "price": 20,
            "options": [
                    "name": "color",
                    "value": "red",
                    "surcharge": 10
                    "name": "shape",
                    "value": "squared",
                    "surcharge": 20

The above payload will generate the signature 50a651873d3d8926f6bb62397f34b1ec7dd3373fc885b28466db8f4022060138.

8. Use the TwoCoInlineCart.cart.setSignature('50a651873d3d8926f6bb62397f34b1ec7dd3373fc885b28466db8f4022060138') method to set the signature. It is important that you employ TwoCoInlineCart.cart.removeAll() just before the TwoCoInlineCart.products.addMany(products) or TwoCoInlineCart.products.add(product) methods to remove previous products as the signature is based on the products' definition.

9. Use theTwoCoInlineCart.cart.checkout()method to show the cart on your page.

Sample request


<a href="#" class="btn btn-success" id="buy-button">Buy now!</a>


window.document.getElementById('buy-button').addEventListener('click', function() {
    name: 'A test dynamic product',
    quantity: 1,
    price: 20,
    options: [
        name     : 'color',
        value    : 'red',
        surcharge: 10
        name     : 'shape',
        value    : 'squared',
        surcharge: 20


After setting the pricing options for dynamic products using the above method, your cart should look like this:
