CURLOPT_XOAUTH2_BEARER(3) Library Functions Manual CURLOPT_XOAUTH2_BEARER(3)

CURLOPT_XOAUTH2_BEARER - OAuth 2.0 access token

#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_XOAUTH2_BEARER, char *token);

Pass a char pointer as parameter, which should point to the null-terminated OAuth 2.0 Bearer Access Token for use with HTTP, IMAP, LDAP, POP3 and SMTP servers that support the OAuth 2.0 Authorization Framework.

Note: For IMAP, LDAP, POP3 and SMTP, the username used to generate the Bearer Token should be supplied via the CURLOPT_USERNAME(3) option.

The application does not have to keep the string around after setting this option.

Using this option multiple times makes the last set string override the previous ones. Set it to NULL to disable its use again.

NULL

This functionality affects http, imap, ldap, pop3 and smtp

{
  CURL *curl = curl_easy_init();
  if(curl) {

    curl_easy_setopt(curl, CURLOPT_XOAUTH2_BEARER, "1ab9cb22ba269a7");
    res = curl_easy_perform(curl);
    curl_easy_cleanup(curl);
  }
