Update Account’s Tax Exemption

The CRM / Ordering system updates an Account’s Tax Exemption flag in the OCS.io via the RESTful API. The request body contains updated Account details. The OCS.io updates the instance of the Account, then returns Business Transaction containing updated Account as a payload of the response. Other systems may be notified about the Business Transaction via the Streaming Platform.

The attribute Tax Exemption in the OCS.io is not versioned. Any changes to this attribute take effect immediately upon update. Please note that these changes do not have a retrospective effect, meaning they do not alter the tax exemption of documents that were created prior to the update.
