Magento Extension to add different product images and prices to the customer shopping cart so that customers can checkout. Product additions without creating extra SKUs On an APP or website, we have the following form. This form need not be on the same Magento Website, it can be anywhere on the web. Customer Email: SKU: Price: Image: The Requirements are as follows: 1) Once the submit button is clicked: a. The SKU, with the chosen image X and Price 10 (example) should be added to the cart of the customer A. b. The image and Price for that particular order will be stored in the customer order history. 2) Customer A will check out using the above data. 3) Customer B will have another order using the above form with the same SKU but will use Image Y with a different image and price 20. 4) Customer B’s order history should show the order with Image Y and Price 20 (example). There is no time lag between the first and second customer, this kind of transaction might happen continuously. We are currently using Magento 2.4. The developer should deliver: 1) Magento Extension to support the above functionality end to end. 2) Provide API so that the above form and functionality can be deployed anywhere on the APP or web. 3) Test and deploy without any flaws.
