Currently available, the Localization Extensions developer preview allows partners and app developers to access the tax id collected during checkout and use this information to augment shipping apps (to expedite customs clearance) and invoicing apps (to issue gov. invoices).
As of the 2020-07 release candidate, orders made through checkout in countries that require a tax id for customs clearance or government invoicing will have this information available through the GraphQL API.
You can try these changes using a development store with the 'Localization Extensions' developer preview enabled.
Okay, so @Jason_Tigas says:
"As of the 2020-07 release candidate, orders made through checkout in countries that require a tax id for customs clearance or government invoicing will have this information available through the REST and GraphQL API."
So from what I understand this is a misunderstanding and there is no such field in the REST API, right? Could you please point developers to where is this field available using the GraphQL API?
Are there any plans to get this to REST API so that webhooks are supported?
We have quite a few merchants looking for these localization extensions and currently the only way is to get a manual Graphl QL query ( https://shopify.dev/tutorials/get-a-country-field-using-localization-extensions ) without any update webhooks.
It would be a great addition and would make the reporting and compliance much easier.
Any update on the plan to expose data from these fields via the REST API? The February 26 deadline is looming.
This is very inconvenient for your customers with an existing Shopify REST API integration: you are introducing required fields to checkout which cannot be disabled, with no way to access the data from those fields...
