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.products.add({code, quantity, options})method to prepare your catalog product.
4. In order to set currency use TwoCoInlineCart.cart.setCurrency(currency-code).
5. In order to set order external reference useTwoCoInlineCart.cart.setOrderExternalRef(your-external-reference)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": "AVLRNG",
    "currency": "USD",
    "products": [
        {
            "code": "74B8E17CC0"
        }
    ],
    "reference": {
        "external": {
            "order": "test-order-external-ref"
        }
    }
}

The above payload will generate the signature f40503a3feeb2c5fc0ca002ded20c59ad0f0b439e3911cfb03538906635d0ae4.
