We are looking to move to Checkout Extensibility upgrade. Currently we have 2 features custom coded into the checkout which I believe when upgraded will need to be added as apps via Checkout UI Extensions.
Can anyone advise 'exactly' how to do this?
Details as follows -
Feature 1 - reduce characters in checkout shipping fields to max 35.
This is currently powered by the custom snippet in checkout-custom.liquid file
Still looking into the best way to do this - in particular reducing characters in shipping fields to 35.
Seems there are 3 options
1. Do via Shopify functions
2. Do via Extensions UI
3. Use a third party adress validator.
Looking for direction on what would be the best option long term?
