Orders and carts
Create a cart for the signed-in member
Create a cart in the member’s company and bind it to the signed-in member in one call. The body is the cart create body of the public carts API (country_code is required; items and attribution are optional). The cart is created in the member’s company only: a company named in the body is ignored, as are member_id, customer_id and an admin source. The response is the cart already bound to the member and priced for them (wholesale for rep member types), with its token, and it is populated before the response. If the bind is refused no cart is left behind. FairShare on a member host makes this one same-origin call (session cookie plus X-CSRF-Token) instead of a public create followed by a claim; guests keep the public create. Claim stays supported. Requires a writable member credential.

session JWT, a portal JWT whose login is linked to a membership in
that company, or an opaque member token. The credential alone
identifies the member and company.
