Create, Update Or Delete WordPress Posts / Custom Post Type Using REST API

There is three-stage of first we need to create a post with a simple one filed Title, Then we need to update the post and delete the post. The same process will work for Post type and Custom post type. 

Create a Post type with REST API

Where to insert all the code from this post? I hope you know this but just in case.

You need a postman and Website through Postman we are going to insert value in post type.

•  The first website – is the website where the post should be created.
•   The second Postman – is the website that will interact with the first website.

We are going to use wp_remote_post() it is a WordPress function it should be inserted somewhere in the WordPress environment. 

$api_response = wp_remote_post( 'https://domainname/wp-json/wp/v2/posts', array(
     'headers' => array(
        'Authorization' => 'Basic ' . base64_encode( 'LOGIN:PASSWORD' )
    ),
    'body' => array(
            'title'   => 'My test',
        'status'  => 'draft', // ok, we do not want to publish it immediately
        'content' => 'lalala',
        'categories' => 5, // category ID
        'tags' => '1,4,23' // string, comma separated
        'date' => '2015-05-05T10:00:00', // YYYY-MM-DDTHH:MM:SS
        'excerpt' => 'Read this awesome post',
        'password' => '12$45',
        'slug' => 'new-test-post' // part of the URL usually
        // more body params are here:
        // developer.wordpress.org/rest-api/reference/posts/#create-a-post
    )
) );
 
$body = json_decode( $api_response['body'] );
 
// you can always print_r to look what is inside
// print_r( $body ); // or print_r( $api_response );
 
if( wp_remote_retrieve_response_message( $api_response ) === 'Created' ) {
    echo 'The post ' . $body->title->rendered . ' has been created successfully';
}

Update a Post type with REST API

We are going update the title of the created post. Replace {POST_ID} with the ID of the post you would like to update. check the below sample

$api_response = wp_remote_post( 'https://domainname/wp-json/wp/v2/posts/{POST_ID}/', array(
     'headers' => array(
        'Authorization' => 'Basic ' . base64_encode( 'LOGIN:PASSWORD' )
    ),
    'body' => array(
            'title' => 'My test 1'
    )
) );
 
$body = json_decode( $api_response['body'] );
 
 
if( wp_remote_retrieve_response_message( $api_response ) === 'OK' ) {
    echo 'The post ' . $body->title->rendered . ' has been updated successfully';
}
 

Delete a Post type with REST API

If you add ?force=true at the end of the request URI, the post will be removed permanently without moving to trash.

$api_response = wp_remote_request( 'https://domainname/wp-json/wp/v2/posts/{POST_ID}', array(  // ?force=true to skip trash
    'method'    => 'DELETE',
    'headers'   => array(
        'Authorization' => 'Basic ' . base64_encode( 'LOGIN:PASSWORD' )
    )
));
 
$body = json_decode( $api_response['body'] );
 
 
if( wp_remote_retrieve_response_message( $api_response ) === 'OK' ) {
    if( $body->deleted == true ) {
        echo 'The post ' . $body->previous->title->rendered . ' has been completely deleted';
    } else {
        echo 'The post ' . $body->title->rendered . ' has been moved to trash';
    }
}

If you don't required Loing just remove Loing functionality from the function and customize based on your requirement.
