REST API v2 — Client registration date not exposed in any endpoint?

API General
1

Hi,

I’m using the REST API v2 to export client data programmatically. In the admin web UI, each client profile shows a “Date and Time of Registration” field — however, I cannot find any way to retrieve this value through the API.

I’ve checked the following endpoints:

  • GET /admin/clients — client list

  • GET /admin/clients/{id} — individual client detail

  • GET /admin/clients/field-values/{id} — custom field values

None of these return a registration/creation timestamp. The individual client record (/admin/clients/{id}) returns: id, name, email, phone, address1, address2, city, zip, state_id, country_id, full_address, is_deleted, can_be_edited, email_promo_subscribed, sms_promo_subscribed — but no date field of any kind.

Question: Is the client registration date accessible via the REST API v2, and if so, through which endpoint or parameter? If it’s not currently exposed, is there a planned addition, or a recommended workaround?

Note: We cannot use the JSON-RPC API (user-api.simplybook.me) as 2FA is enabled on our account, which blocks that authentication flow.

Thanks in advance.
