Use the Product object to add a dynamic product to the InLine Cart by calling the click event handler.

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. Use theTwoCoInlineCart.setup.setMode('DYNAMIC')method in order to let the cart know you are using dynamic instead of catalog products.
  4. In order to set currency useTwoCoInlineCart.cart.setCurrency(currency-code).
  5. Add your product to the cart by calling theTwoCoInlineCart.products.add({name, quantity, price, options}) method.
  6. 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

The above payload will generate the signature 718e810fee34be2bf4b9d4582323aa37580c4011ef694116cca5b0bb7badd2f1.

7. Use the TwoCoInlineCart.cart.setSignature('718e810fee34be2bf4b9d4582323aa37580c4011ef694116cca5b0bb7badd2f1') 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.

8. 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,


After adding the dynamic product to the InLine checkout using the above method, your cart should look like this:
