How to upload image using api on matlab?

Hi,

I tried various variations of this code.

url = 'https://api.cloudinary.com/v1_1/mycloudname/image/upload'; input = struct('file',fileName,'api_key','myapikey','upload_preset','mypreset','timestamp','173759331'); options = weboptions('MediaType','application/json'); response = webwrite(url, input, options);

But I always get the (400) bad request.

Thanks for help.
