You can edit the details of placing orders with a supplier using the Edit Supplier Ordering Details endpoint.

Order approval settings

order_approval_enabled, daily_order_threshold and approver_roles are returned to every library with their stored values, whether or not it has the Order Approval module.

• Without the module, a request that changes any of them is refused with 400, naming only the fields whose value differs from the stored one. Sending the stored values back is accepted, so a record that is read and written back whole goes through.
• approver_roles is written as role IDs. It is read as role objects (id, name) and written as a list of their IDs, like a user connector's role. Sending the objects back is refused with 400.
• Enabling needs a threshold. order_approval_enabled: true without a daily_order_threshold is refused with 400 on daily_order_threshold.
• Roles are checked when written. Each one must belong to the library, be a library or outlet role and hold the Approve Orders permission; otherwise the request is refused with 400 on approver_roles, listing the rejected IDs.
