Authentication Token Persistence

[UltraWelfare]

As far as I understand the token is stored in memory

laravel-viva-payments/src/Client.php

Lines 221 to 230 in 52796a9

	public function authenticateWithBearerToken(): array
	{
	$token = $this->token ??= $this->oauth()->requestToken()->access_token;
	return [
	RequestOptions::HEADERS => [
	'Authorization' => "Bearer {$token}",
	],
	];
	}

Which means that if, for ex; N users do a Viva::orders()->create call -> N authentication calls to Viva would happen. Each request would use a different token.

Shouldn't the authentication call be done once, then refresh when it expires? Probably store it using cache or something equivalent.

The token is stored in memory, which means in the current lifecycle the same token is being used, because the Client is a singleton.

If you want to store the token until it expires, you have to cache it like this:

// get the token from the cache or store it until it expires
$token = Cache::get('viva.token', function () {
    $token = Viva::oauth()->requestToken();

    Cache::put('viva.token', $token->access_token, $token->expires_in);

    return $token->access_token;
});

// set the token to the client
Viva::withToken($token);
