# Get a workspace's billing details

> Who a workspace's invoices are made out to: the billing email, name, address, tax ID (tax_id_type, tax_id), po_number and the invoices' language, with the default payment_method as far as it is safe to show (its kind, brand, last four digits and expiry).

<div class="g1t-endpoint"><span class="g1t-method" data-method="get">GET</span><code>/workspaces/{workspace}/billing_details</code></div>

`customer` is false until the workspace has been set up to pay. Tax is worked out from the address: `tax_location` says whether it is enough for that (a country, and in the US a ZIP code), `tax_address_needed_at` is set while g1t is holding a charge for want of one, `tax_id_status` is Stripe's check of the tax ID (`pending`, `verified`, `unverified` or `unavailable`), and `tax_exempt` is `none`, `exempt` or `reverse`. Members of the workspace only.

Owners change these on the workspace's billing page. `payment_method` is null until a card or other way to pay is saved. Tax is worked out from the address: `tax_location` is false until it has at least a country (and in the US a ZIP code), and `tax_address_needed_at` is set while a charge waits for one.
