We are trying to create an order and apply a coupon code using woo commerce API as explained in the woo commerce documentation. following is the JSON we are trying to send with the API request.
{
"order":{
"payment_details":{"method_id":"cash","method_title":"cash","paid":false},
"billing_address":{"first_name":"kamran","last_name":"masud","company":null,"address_1":"Dubai Dubai - United Arab Emirates",
"address_2":null,"city":null,"state":null,"postcode":null,"country":null,"email":null,"phone":"541234566"},

"address_2":null,"city":null,"state":null,"postcode":null,"country":null},
"customer_id":116,
"line_items":[

"shipping_lines":[],
"fee_lines":[
{"id":0,"title":"Shipping :","tax_class":null,"total":"0","total_tax":null}
],
"coupon_lines":[
{
"code":"fixedcart10",
"discount":"80",
"meta_data":[
{
"key":"coupon_data",
"value":[
{
"id":"168026",
"code":"fixedcart10",
"amount":"10"
}
]
}
]
}
],
"discount_total":null,
"shipping_total":null,
"total":null,"status":"processing"}}
