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 en‐
       code 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) op‐
       tion 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

       Returns CURLE_OK
