Change title of page dynamically in page - php

Question

I have an page (with snippet code and short code and manual php code) and it call a REST API and base Of response, I want change tag title of this page (Not in database).and it was change every call.
i try do :
in snippet code:
$GLOBALS['MyTitle'] = $response-> title;
in function:
function change_title($title) {
$variable = $GLOBALS['MyTitle'];
if (!empty($variable))
{
$title = $variable;
}
return $title;
}
add_filter('pre_get_document_title', 'change_title',500);
but it was empty every time because the function section run sooner then snippet code(Api Call).
WordPress has not any function for change title tag text? like wp_set_title('my title') to use without add_filter?

Answer 1

Changing title of the page dynamically by applying the filter the hook used for the filter is document_title_parts. Here is the official wordpress documentation link and below is the example. In this example i have used get method for API.
add_filter( 'document_title_parts', 'function_to_dynamic_title');
function function_to_dynamic_title( $title_parts_array ) {
$request = wp_remote_get( 'https://dummyjson.com/products/1' );
if( is_wp_error( $request ) ) {
return $data;
}
$body = wp_remote_retrieve_body( $request );
$data = json_decode( $body );
$title_parts_array['title'] = $data->title;
return $title_parts_array;
}

In WordPress, we have an action to change the title programmatically.
add_filter('the_title','your_callback_function');
function your_callback_function($data)
{
global $post;
// add your condition according to page
return 'Desired Title'. $post->ID;
}
