Connecting WordPress and Flarum to generate threads from posts

Oshvam

I would like to know if there is a way to connect the WordPress Rest API and Flarum so that my blog posts are automatically published on Flarum as a new discussion.

I think this would be a good idea for many WordPress sites to implement Flarum as a forum system.

Maybe something like this, but I am not able to get WordPress to choose the chosen tag.

function publish_in_flarum($post_ID) {
    $post = get_post($post_ID);
    $title = $post->post_title;
    $excerpt = $post->post_excerpt;
    $link = get_permalink($post_ID);

    $data = [
        "data" => [
            "type" => "discussions",
            "attributes" => [
                "title" => $title,
                "content" => "$extracto[Leer más]($link)"
            ]
        ]
    ];

    $ch = curl_init("domain/api/discussions");
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
    curl_setopt($ch, CURLOPT_HTTPHEADER, [
        "Authorization: API KEY GENERATED",
        "Content-Type: application/json"
    ]);

    $response = curl_exec($ch);
    curl_close($ch);
}

add_action('publish_post', 'publish_in_flarum');
