Send request to WordPress REST API

Question

I have a server (server 1) which send requests to another server (server 2) where WordPress is installed and I am using their (server 2) WP REST API.

The problem is that I can't create/send wp-nonce from server 1 to server 2, and I am getting the following response:

{
"code": "rest_not_logged_in",
"message": "You are not currently logged in.",
"data": {
    "status": 401
}
}

I know that is not easy to disable nonce for REST API, but what is the proper way to send requests from another server to the WP REST API ?

Answer 1

Since your specific scenario is a remote application making a request to WordPress you'll need to explore additional authentication methods available via plugins for the REST API. I won't make any specific recommendations since I don't know your use case in detail but I'm sure you will find one that works well.

Answer 2

Try adding the following to your theme's functions.php file at the top. This will allow you to use Cross Domain calls from your functions.php.

function add_cors_http_header(){
    header("Access-Control-Allow-Origin: *");
}
add_action('init','add_cors_http_header');
