wp_remote_post runs 3 times with plugin

I’m having an issue where wp_remote_post runs 3 times but is in the code once. I added the code to the “Posts” tab in the “Before the post content”.

Here is part of the code:

<?php
$postID = get_the_ID();
$array_with_parameters->blog_id = $postID;
$args = array(
    'headers' => array(
        'Content-Type' => 'application/json; charset=utf-8'
    ) ,
    'body' => json_encode($array_with_parameters) ,
    'method' => 'POST',
    'data_format' => 'body'
);

$url = 'https://apiendpointgoeshere.com';
$response = wp_remote_post($url, $args);

Can the plugin prevent wp_remote_post from running 3 times? I tried echo to show output but the output shows up once.
