NAME
       CURLOPT_POSTFIELDS - data to POST to server

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_POSTFIELDS, char *postdata);

DESCRIPTION
       Pass  a  char  *  as parameter, pointing to the full data to send in an
       HTTP POST operation. You must make sure that the data is formatted  the
       way  you  want  the  server  to receive it. libcurl will not convert or
       encode it for you in any way. For example, the web  server  may  assume
       that this data is URL encoded.

       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.  This behavior can be changed (so libcurl does copy
       the data) by setting the CURLOPT_COPYPOSTFIELDS(3) option.

       This POST  is  a  normal  application/x-www-form-urlencoded  kind  (and
       libcurl  will  set  that  Content-Type  by  default when this option is
       used), which is commonly used by HTML forms. Change  Content-Type  with
       CURLOPT_HTTPHEADER(3).

       You  can use curl_easy_escape(3) to URL encode your data, if necessary.
       It returns a pointer to an encoded string that can be passed  as  post‐
       data.

       Using CURLOPT_POSTFIELDS(3) implies setting CURLOPT_POST(3) to 1.

       If  CURLOPT_POSTFIELDS(3)  is  explicitly set to NULL then libcurl will
       get the POST data from the read callback. If you want to send  a  zero-
       byte  POST  set  CURLOPT_POSTFIELDS(3)  to an empty string, or set CUR‐
       LOPT_POST(3) to 1 and CURLOPT_POSTFIELDSIZE(3) to 0.

       libcurl will use assume this option points to a null-terminated  string
       unless  you  also set CURLOPT_POSTFIELDSIZE(3) to specify the length of
       the provided data, which then is strictly required if you want to  send
       off null bytes included in the data.

       Using  POST  with  HTTP 1.1 implies the use of a "Expect: 100-continue"
       header, and libcurl will add that header automatically if the  POST  is
       either  known to be larger than 1MB or if the expected size is unknown.
       You can disable this header with CURLOPT_HTTPHEADER(3) as usual.

       To make multipart/formdata posts,  check  out  the  CURLOPT_MIMEPOST(3)
       option combined with curl_mime_init(3).

DEFAULT
       NULL

PROTOCOLS
       HTTP

EXAMPLE
       CURL *curl = curl_easy_init();
       if(curl) {
         const char *data = "data to send";

         curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");

         /* size of the POST data */
         curl_easy_setopt(curl, CURLOPT_POSTFIELDSIZE, 12L);

         /* pass in a pointer to the data - libcurl will not copy */
         curl_easy_setopt(curl, CURLOPT_POSTFIELDS, data);

         curl_easy_perform(curl);
       }

AVAILABILITY
       Always

RETURN VALUE
       Returns CURLE_OK
