Question

I am constantly receiving a 415 Unsupported Media Type when making a "POST" using the skyscanner.com Live Request API. I am using both postMan and the swift platform and receiving the same 415 error message on both. My url is: http://partners.api.skyscanner.net/apiservices/pricing/v1.0?country=UK&currency=GBP&locale=en-GB&locationSchema=iata&originplace=EDI&destinationplace=LHR&outbounddate=2017-05-30&inbounddate=2017-06-02&adults=1&children=0&infants=0&apikey= prtl6749387986743898559646983194 and my headers are: Content-Type : application/x-www-form-urlencoded Accept: application/json

The header type and query sting is as required per api:
