Changelog

v1.0.9

Added OAuth2 client-credentials support. Pass clientId/clientSecret instead of apiKey and the SDK handles the token exchange and refresh automatically:

1
$client = new PayabliClient(
2
    clientId: "...",
3
    clientSecret: "...",
4
    options: ['baseUrl' => Environments::Sandbox->value]
5
);

The existing apiKey-based constructor still works unchanged — no action needed if you’re not switching auth methods. See the PHP SDK guide and Authentication to compare both methods.
