laravel queue works in postman but not in browser

I have an api that sends emails using a job, I test it in postman and it works perfectly but when I call it from a button (in another app calling the api) it does not execute the job. any suggestion? Thanks

public function test()
{
    $data['pass'] = 'FnJKfkuG';
    $data['name'] = 'Gordon';
    $data['route'] = 'myapi.test/validate-email/jQZSPFSZLuBqAdQofxtV5Bw2TK4ZcrNmoxFFR5ZvgGM48gHyKcxv7y6jHBaZhHIF';
    $data['email'] = 'abc@gmail.com';
    $data['title'] = 'Hi!!';
    $data['body'] = 'Text here.';
    SendEmailJob::dispatch('', $data,'','', $data['email'],'welcome');
}

SendEmailJob code uses sendMail function

sendMail($this->mailto, 'Confirmación de solicitud', 'newRequest', $this->data, 'mi correo');

function sendMail($mailTo, $subject, $view, $data, $from)
{
    try {
        Mail::to($mailTo)->send(new SendMail($from, $data, $view, $subject));
        return sendResponse('Ok');
    } catch (\Exception $e) {
        Log::debug($e->getMessage());
        return sendExceptionError('Error 2',$e->getMessage());
    }
}

SendMail is a mailable class

it works in postman with the route: myapi.test/api/v1/test, the job y executed and email is sent

but when I call this route from another project, it does not work

I try to debug it using logs, when use postman it works like a charm but when use it in a button it has an error: Expected response code "250" but got code "530", with message "530 5.7.1 Authentication required". then, the job does not execute.

it is so weird, I dont understand why

Help me please, sorry my bad english

Thanks

I trying to send email using a laravel job

SOLVED: I copied the email configuration from the .env file and config/mail.php in the api project to .env and config/mail.php in the app project. I don't know if it's the best or correct solution, but it works now. Thank you all for the answers.
