Laravel-passport for external api

As nobody can answer me

i respond to myself

i did not find a way to do it

Here is code how i can achieve it without laravel-passport :

<?php

// from my own ZoomService

....

    public function base64UrlEncode($string)
    {
        return str_replace(['+', '/', '='], ['-', '_', ''], base64_encode($string));
    }

    public function generateJWT()
    {
        $headers = json_encode([
          'alg' => 'HS256',
          'typ' => 'JWT'
        ]);

        $payload = json_encode([
          'iss' => config('services.zoom.key'),
          'exp' => now()->addDay(1)->timestamp
        ]);

        $base64Header = $this->base64UrlEncode($headers);
        $base64Payload = $this->base64UrlEncode($payload);

        $data = sprintf(
            '%s.%s',
            $base64Header,
            $base64Payload
        );

        $signature = hash_hmac('sha256', $data, config('services.zoom.secret'), true);
        $base64Signature = $this->base64UrlEncode($signature);

        /*
        HMACSHA256(
        base64UrlEncode(header) + "." +
        base64UrlEncode(payload),
        API_SECRET)
        */
        $token = sprintf(
            '%s.%s.%s',
            $base64Header,
            $base64Payload,
            $base64Signature
        );

        return $token;
    }

maybe it could help us
