Update or Set new default fonts in Elementor from your plugin or theme

set-default-fonts-in-elementor-from-theme-or-plugin.php

<?php 

add_action('elementor/loaded',  'prefix_register_custom_default_fonts');

// register custom fonts only when elementor is ready
function prefix_register_custom_default_fonts(){

$new_default_fonts = [
      //Primary Headline
			[
				'font_family' => 'Playfair Display',
				'font_weight' => 400
			],
      
       //Secondary Headline
			[
				'font_family' => 'Lora',
				'font_weight' => 400
			],
      
       //Body Text
			[
				'font_family' => 'Nunito Sans',
				'font_weight' => 400
			],
      
      //Accent Text
			[
				'font_family' => 'Nunito Sans',
				'font_weight' => 400
			],
		];
        
		$typography = new \Elementor\Scheme_Typography();
		$typography->save_scheme( $new_default_fonts);
    
    /*
    
    get saved fonts in anywhere in your theme/plugin. You will receive an array of 4 fonts.
    $updated_fonts = $typography->get_scheme_value();
    
    NOTE: You may want to use an option to track update of this method, because you need to make sure you update the default fonts once, 
    Otherwise, when a user change the fonts from elementor editor, it will be overridden by your function. I prefer to follow a style like below.
    
    if (!get_option( 'prefix_updated_elementor_fonts')){
				$typography = new Scheme_Typography();
				$typography->save_scheme( $xlaw_default_fonts);
				update_option( 'prefix_updated_elementor_fonts', 1);
		}
