The creation of ttn works strangely (it used to work correctly)

Based on the solution to the problem earlier in the topic https://crm-onebox.com/ru/support/logistics-and-delivery-services/8136-ttn-dzhastin-vsegda-stoit-nalozhka/#answer28464 (see the screenshot indicated in the comment topic) - Justin tech support pointed out that if you don't need an overlay, don't send the body of the order_amount payment and the sign that order_payment_is_required must be paid Both parameters are sent according to your TTN and it is calculated that otherwise there will be a cash on delivery. An example of the request parameters part: array ( [api_key] => [integration key] [data] => array ( [number] => 1160 [date] => 2021-10-17 [sender_city_id] => e156e3c8-dbfb-11e7-80c6-00155dfbfb00 [sender_company] => FOP Podolyanets Alexander Vasilyevich [sender_contact] => Podolyanets Alexander Vasilyevich [sender_phone] => +380982450939 [sender_pick_up_address] => [sender_branch] => [pick_up_is_required] => 1 [receiver] => Kurenya Anna Nikolaevna [receiver_contact] => [receiver_phone] => +380979365812 [count_cargo_places] => 1 [branch] => 7100103173 [weight] => 7 [dimensional_weight] => 0.25 [volume] => 0.001 [declared_cost] => 1049 [delivery_amount] => 52.3 [redelivery_amount] => 36 [order_amount] => 1049 [redelivery_payment_is_required] => [redelivery_payment_payer] => 1 [delivery_payment_is_required] => 1 [add_description] => [delivery_payment_payer] => 1 [order_payment_is_required] => 1 [delivery_type] => 0 [code_transfer_type] => 2 ) ) I recommend that you contact Justin tech support to get an answer why you do not create a cash on delivery when the appropriate parameters are passed to them. Probably they either have some innovations, or different working conditions for different clients.
