AJAX 400 Bad Request Worpress PHP-CodePudding

I'm currently using a GraphQL API with Ajax & PHP on Worpress.

First things first, everything is working as well as expected on my browser/account. But as soon as I change my google user or different browser or going on my phone. My ajax request get a 400 from my admin-ajax.php.

Honestly, I have no idea what is the problem, I'm just doing a simple request on php with ajax, then I make a GraphQL query in my back, then I send it back in JSON format in my front. That's all. I have 400 bad request w/e I try to do in my back. I have no clue what to do neither where to look for.

This is one of my ajax request.

ajaxurl is defined no worries:)

 $.ajax({
    type: 'post',
    url: ajaxurl,

    data: {
      'action': 'get_content_wino'
    },
    success: function(data){
        console.log(data);
        console.log("fetch ok")
    },
    error: function(errorThrown) {
        console.log(errorThrown);
    }
  });

This is my back.


function get_content_wino()
{
   if ( isset($_REQUEST) )
   {
       echo read_file();
       die();
   }
}

add_action( 'wp_ajax_get_content_wino' , 'get_content_wino' );

w/e my action is I get 400. on admin-ajax.php

Quick reminder, everything is perfectly working as long as I have the same browser and google accounts. There is no ip whitelist or login account on my website, pure ajax and php here.

Thanks

There are two action hooks when you hook into wp_ajax.

wp_ajax_{$action} for for logged-in users. Docs

and

wp_ajax_nopriv_{$action} for logged-out users. Docs

So to combine the two, you could use the following code:

add_action( 'wp_ajax_get_content_wino' , 'get_content_wino' );

add_action( 'wp_ajax_nopriv_get_content_wino' , 'get_content_wino' );

function get_content_wino()
{
   if ( isset($_REQUEST) )
   {
       echo read_file();
       die();
   }
}
