How to caculate the same Shipping methods for all the apps products

[Rajkumar1]

Hello,

I have one store in Shopify and enabled the shipping method "UPS" and appear on the checkout page that will fine, I have installed multiple apps and publish those products to my store, for example, the apps are customcat, printfy, printful, fuel, these apps products also I want to display the same shipping options. How can we do it? When we enabled those shipping options, is that way to connect to the UPS shipping account. Please give clarity on this.

Thanks in advance.
