Checkout 2.0


On this page you will find information about how to Process the result and the different Purchase states through out the CheckOut session.

Processing the Result

The last step occurs when the customer finishes working with the form and there’s a result available. The client script signals this by calling the done callback function (see Showing the Check-Out Form).

The done callback doesn’t contain any information about whether the payment succeeded or not. It only signals that the customer is done working with the form. The partner site back-end must check what the actual result was. We have designed it this way as a security measure, so that the partner integrators aren’t tempted to trust the client script. Unfortunately, there’s no way to prevent malicious customers from modifying the script since it runs in their browsers.

The implementation of the done function is up to partners. However, a common scenario (unless the site is a single-page application) would be to perform a redirect to a page that verifies the result, passing the Purchase ID is a parameter in the URL:

//example of done function passed as part of the options for AvardaCheckOutClient.init function
var options = {
    done: function (purchaseId) {
        window.location.href = "/done.php?purchaseId=" + purchaseId;

The done.php page would then make a call to the GetPaymentStatus API function in order to check the actual result. If the payment was successful, the partner site might want e.g. to mark the order in its own database as paid and show a confirmation message to the user. If the payment wasn’t successful, the partners site should display an error message at least.

When the checkout process is completed a call to defined done method will be performed.
This function normally redirects the user back to order confirmation page, before showing confirmation merchant should verify purchase details by calling GetPaymentStatus.

Purchase States

Each individual Purchase changes its state during a Check-Out session. The following diagram shows valid transitions between the states:

The states shown in green are intermediate, meaning that the purchase cannot stay in neither of them for a long time. States of all other colors are terminal. Once a purchase makes a transition into one of such states, it stays in it forever.

Enumeration States

The enumeration describes the state of a single Purchase. Please refer to the diagram in Purchase States chapter to see possible transitions between states.
