Hi, We are looking for someone that could add a feature to our custom customization tool on shopify. Currently, our system adds two canvases with the user customizations that overlay on the product picture. To capture the current engraving for visual reference, we convert the canvases to base64 code. Our goal now is to utilize the Cloudinary API to upload the current product picture and its corresponding base64 code of the customization, merge them and upload to Cloudinary. This process will generate a URL for the merged image, which will then be added as a product option to the cart. It's important to note that this operation should occur exclusively when the product is added to the cart, mitigating the need for frequent API usage. Any questions please ask. Thanks!
