New Integration New Mail and checkbox

Good afternoon. Documentation on integration with NovaPay from Checkbox via API - https://api.checkbox.in.ua/api/redoc#tag/Integraciya-z-Novoyu-Poshtoyu/operation/post_ettn_order_api_v1_np_ettn_post Implementation of actions of creation/deletion of creation of express waybill receipt will take about 25-30 hours, but for a more specific assessment if you need specific functionality according to the documentation - specify the technical specifications. After all, it is possible to develop, for example, a change in the stage of the process after automatic fiscalization of the receipt after changing the status of the consignment note. I would also like to draw your attention to the fact that in fact this does not automate the creation of the consignment note - according to the documentation https://wiki.checkbox.ua/uk/portal/cash-registers/nova-poshta you must have the integration configured in the Checkbox personal account for integration with the NP, and also before the request in Checkbox to create a check for the NP consignment note - the latter must already be created on the NP side
