Checkout error - "Your order has already been submitted successfully"

Problem Statement

This article helps you understand checkout error - "your order has already been submitted successfully".

Solution

This error usually occurs if you are using the incorrect checkout page URL. The URL that you seem to be using is the one generated upon accessing the plan specific hosted page successfully.

You would see the session ID embedded in it and the same URL cannot be used multiple times once the checkout is completed. This URL will hence throw the error - "Your order has already been submitted successfully".

The right URL that you need to embed on your website is the plan specific URL which can be found under Product Catalog > Plans. Click on Copy URL and you can embed the URL on your website:

Replace the site name and plan ID with your site name and plan ID as specified below. For example, if your site name is 'acmeinc' and your plan ID is 'monthly_plan' then this is how your URL would look like:

https://acmeinc.chargebee.com/hosted_pages/plans/monthly_plan

and the hosted page URL with the token (the page on which customer lands in after successful checkout) would look like this - https://acmeinc.chargebee.com/pages/v2/kzxPnK2B61CEOCfcd5nCaWnnt3aUQ6YRM/thank_you
