curl https://api.goshippo.com/v1/tracks/ -H "Authorization: ShippoToken <TOKEN>" -H "Content-Type: application/json" -d {"tracking_number":"<TRACKING_NUMBER>"}
But i am send a response as below
{"detail": "JSON parse error - Expecting property name enclosed in double quotes: line 1 column 2 (char 1)"}
