  I’ve searched a lot how to use the api in wordpress but I didn’t find a real guide step by step for newbies such as me

  I’m feeling lost and don’t know where I can start from.

  but when I’ve searched for wordpress projects I haven’t found a project start from zero step to publish the post!

  as I’ve learned, I have to make an app to get something as access token to be able to use the api

  after searching I’ve found WordPress.com Connect.

  So I’ve applied everything and get the message “Connection successful!” when callback but when I try to get access_token key, I get a server message:

  Notice: Trying to get property of non-object in C:wampwwwwordpresscallback.php on line 42

  here is defines.php:

  define( 'CLIENT_ID', "XXXXXX" ); 
  define( 'CLIENT_SECRET', 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXX' );
  define( 'LOGIN_URL', 'https://engnajjar.wordpress.com/wp-admin/' );
  define( 'REDIRECT_URL', 'http://127.0.0.1/wordpress/callback.php' );
  
  // You do not need to change these settings
  define( 'REQUEST_TOKEN_URL', 'https://public-api.wordpress.com/oauth2/token' );
  define( 'AUTHENTICATE_URL', 'https://public-api.wordpress.com/oauth2/authenticate' );

  here is callback.php:

  require_once dirname( __FILE__ ) . '/defines.php';
  
  // If someone visits this page without a <code>code</code> value, it's likely they've not 
  // been authenticated or declined access, so redirect them to the login page.
  if ( ! isset( $_GET[ 'code' ] ) ) {
  	header( 'Location: ' . LOGIN_URL );
  	die();
  }
  
  // We pass an anti-forgery state value when redirecting the visitor, so upon
  // arrival here, we verify that the returned value matches our expectations.
  session_start();
  if ( $_GET[ 'state' ] !== $_SESSION[ 'wpcc_state' ] ) {
  	die( 'Warning! State mismatch. Authentication attempt may have been compromised.' );  	
  }
  
  // When redirected, a temporary, time-sensitive code will be included as a 
  // query parameter. This needs to be exchanged for an authorization token.
  $code = $_GET[ 'code' ];
  
  $curl = curl_init( REQUEST_TOKEN_URL );
  curl_setopt( $curl, CURLOPT_POST, true );
  curl_setopt( $curl, CURLOPT_POSTFIELDS, array(
  	'client_id'     => CLIENT_ID,
  	'redirect_uri'  => REDIRECT_URL,
  	'client_secret' => CLIENT_SECRET,
  	'code'          => $code,
  	'grant_type'    => 'authorization_code'
  ) );
  
  curl_setopt( $curl, CURLOPT_RETURNTRANSFER, 1 );
  $auth = curl_exec( $curl );
  
  // The JSON response can be decoded to an object containing the access_token 
  // that you will use to query the users profile information.
  $secret = json_decode( $auth );
  
  echo 'Connection successful!';

  if I add this line:
  $access_key = $secret->access_token;

  I get the previous server message

  how to continue please ?

  Hi there,

  This support forum provides support for end-users of free WordPress.com sites. We do not provide API support here.

  You can find our API documentation for the WordPress.com API at the following link:

  https://developer.wordpress.com/docs/api/

  For help with that API you can use the contact form at https://developer.wordpress.com/contact/, but we do not provide in-depth support with using the API.

  If you’re looking for information on the REST API in WordPress Core, you can find that here:

  https://developer.wordpress.org/rest-api/

  For help with the coding aspect of using either API, I suggest you ask in a developer forum instead, like the WordPress StackExchange:

  https://wordpress.stackexchange.com/
