Our solution is not a stationary module. But we set up your solution directly with your website. The solution is a PHP script placed in a separate folder on your site, and it works with the database directly. On the Printful side, the Printful API is used. The solution allows you to export products from Printful to Opencart and update information (most often the price is updated, but other parameters can be used for updating). Printful receives all orders received from customers through Opencart website. Please write what is needed for your business from the mentioned things, or what additional functions you would like to see. We will estimate the cost of the work.
