mollie/mollie-api-php v3.16.0

on PHP Packagist

This release backports the voucher category fix from v4.1.0 to the v3 line and includes the fixes and additions merged since v3.15.0. PHP 7.4 remains supported.

Fixed

• Voucher payments: preserve category and categories on OrderLine and in its factory. Use categories for payment and payment-link lines, and category for order lines. This is the PHP 7.4-compatible backport of #947.
• Sales invoices: hydrate collections returned under _embedded.invoices, retaining registry names and legacy response aliases (#943).
• HTTP failures: classify network and request errors consistently with Guzzle 7 and 8. Preserve original exceptions, avoid retrying malformed requests, and do not treat incomplete transfers as completed HTTP responses (#944).
• Checkout Sessions: align request and resource models with the API specification (#931).

Added

• Checkout Session requiredCustomerDetails support in request objects and factories, plus requiredCustomerDetails, profileId, createdAt, expiredAt, and completedAt on session resources. Customer-detail collection is a private-beta API feature (#931).
• Guzzle 8 compatibility (#944).

Deprecated

• Checkout Session cancelUrl and Session::getRedirectUrl() are documented as deprecated: the API does not accept a cancel URL and returns only a self link. Use clientAccessToken with Mollie's client-side components (#931).

Documentation and maintenance

• Clarify that Google Pay payments use PaymentMethod::CREDITCARD, with googlePayPaymentToken for direct integration. PaymentMethod::GOOGLEPAY remains a wallet identifier for the Methods API, not a valid Create payment method (#933).
• Keep legacy reflection access in tests only on PHP versions that need it (#946).
