how to redirect the page in wordpress with XML-RPC API

how to input redirect code in wordpress, using xmlrpc.php like

<meta http-equiv="refresh" content="0;url=landing page address/">

I made auto posting program with python. I put the

<meta http-equiv="refresh" content="0;url=landing page address/"> 

in html source code. (landing page address is changing in every post).

I asked google Bard.

The reason why the code is erased automatically is because the XML-RPC API doesn't allow you to return HTML. Instead, you can use the wp_redirect() function to redirect the user to the landing page address. Here is an example of how to use it:

<?php
function auto_post_with_redirect() {
  // Get the post ID
  $post_id = 123;

  // Get the landing page address
  $landing_page_url = 'https://www.example.com/landing-page';

  // Redirect the user to the landing page
  wp_redirect($landing_page_url, 301);
  exit;
}

// Hook the function to the `xmlrpc_publish_post` action
add_action('xmlrpc_publish_post', 'auto_post_with_redirect');

This function will redirect the user to the landing page address after the post has been published.

Here are some additional things to keep in mind when using the wp_redirect() function:

The wp_redirect() function accepts two arguments: the URL to redirect to and the status code. The status code can be either 301 (permanent redirect) or 302 (temporary redirect). The wp_redirect() function will only redirect the user if the current request is a POST request. The wp_redirect() function will not redirect the user if the current request is a GET request. I hope this helps!

So Would you teach me how to set $landing_page_url as variable, and how to input that in html code?

I think it wount't work " " in html at article in wordpress.

How to make landing page address as variable? and How to call that function in html?

Thank you so much in advance.

I've tried to ask chatGPT, Bard, Bing etc.
