# Custom domain connect endpoints and tax ID collection

*Version 1.281 – released 2026-06-17*

## Custom domain connect endpoints

Connecting a custom domain to a store is now an API call. Agencies and anyone provisioning stores programmatically can attach a domain and follow its verification state without clicking through admin.

## Tax ID collection at checkout

Checkout collects a buyer's tax ID through Stripe's TaxIdElement, so B2B orders arrive with a VAT or company number already attached instead of chasing it afterwards.

## Also shipped
- Store social links can be set through the API, alongside the rest of the store profile
