2022 Is it Checkout Pop-ups, Shopify vs Shopify Plus

I see apps that can be added to shops that generate pop-ups. One in particular I saw was an address validation service where after a user enters an address a pop-up appears telling the user, if the address was bad, that the address had a problem and that it should be fixed.

What I want to do is similar to that workflow. Upon an end user entering an address, I want to call a third party API to validate the address and display back to the user in real-time the deliverability of the address.

Why not use the the 3rd party app you may ask? I have my own API to do the address validation and many others so I want to call my own services.

Specifically, now in 2022 with all the things that have been updated with the platform these are my questions:

#1 Is it possible?

#2 Is it possible in Shopify or Shopify Plus or both?

#3 If it’s only possible in Shopify Plus do I need to pay for a Shopify Plus account to be able to create and test it?

#4 Can this work in the checkout module or other modules that involve end user data entry?

#5 Any documentation that spells this out more clearly would be helpful.

@jrjanrejr yes its possible with carrier calculated shiiping enabling shopify

it will allow to check shipping address with post code for clients on checkout.

you have to be on shopify advance or plus plan or pay extra $20+ per month if on basic or shopify plan.

@jrjanrejr Here is an example of post code checker app https://apps.shopify.com/postcode-shipping-extension in checkout after enabling carrier calculated shiiping in shopify

The address validation we do does more than just check postal codes on addresses. It fixes typos, it tells you what’s missing like if the apt was missing or out of range for the address, if its residential or business, is it general delivery or PO Box, is it military, is the address existing but vacant and so on. So I am looking for a doing this kind of workflow but with my address validation which is more detailed than most things on the market.
