My POST request values returns NULL.

You could check if the field names match in your form. Sometimes a misspelled input name is the culprit.

Thank you for your answer. I don't have any form, because I'm sending the key:value pair directly.

Are you POSTing raw JSON; have you structured it correctly:

{
    "key": "value"
}

Hi tykus. I don't know, I'm sending the values like this: https://i.hizliresim.com/1EQYB5.png

I also tried to send the values from an application, it still returns null.

Can't see that link @Sphynxinator

That image doesn't work.

I added my link as "/login" to VerifyCSRFToken Middleware except list

Try removing the / in that. I don't know if it matters though.

Can you try this link: https://imgur.com/a/ONHzI0V

    $name = $request->input('username');
    $password = $request->input('password');

    echo $name;
    die();

And I'm trying to take the values like this.

What does your controller look like?

Use the Body with JSON like I described earlier rather than Variables (they're for something else).

{
    "username": "example_username",
    "password": "example_password"
}

Set the Body Content Type to application/json.

Alternatively, set the Body Content Type to application/x-www-form-urlencoded and specify key/value pairs like you were doing with Variables - this will simulate a HTML form being submitted to the specified URL

Thank you, it works.
