LibCurl seems to escape my POSTFIELDS

Question

I'm using this code to post json to a server:

But it seems like CURL somewhere in the way escapes the data, ie transforms it into "{\\"email\\":\\"test@example.se\\"}" (Makes my quotes escaped). I think curl still posts with the Content-Type "application/x-www-form-urlencoded", even thou I've overwritten it with application/json in my headers. How can I make curl not do that?

curl_easy_setopt(curl, CURLOPT_URL, url.c_str());
curl_easy_setopt(curl, CURLOPT_POST, 1L);
const std::string& data = "{\"email\":\"test@example.se\"}";
curl_easy_setopt(curl, CURLOPT_POSTFIELDS, data.c_str() );
curl_easy_setopt(curl, CURLOPT_POSTFIELDSIZE, data.size() );
// Headers
curl_easy_setopt(headers, "Content-Type: application/json");
curl_easy_setopt(headers, "Authorization: Basic: something:something");
curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headers);
curl_easy_perform(curl);

From here: http://curl.haxx.se/libcurl/c/CURLOPT_POSTFIELDS.html

libcurl will not convert or encode it for you in any way.

The data pointed to is NOT copied by the library: as a consequence, it must be preserved by the calling application until the associated transfer finishes.
