stripe/stripe-php v21.3.0

on PHP Packagist

This release changes the pinned API version to 2026-08-26.dahlia.

• #2113 Support discriminated unions in the V2 runtime and fix array coercion

  • Adds support for nullable and discriminatedUnion field encodings in the V2 coercion runtime, so int64 and decimal fields wrapped in those schema kinds convert correctly.
  • Encoding a V2 request throws \Stripe\Exception\InvalidArgumentException when a polymorphic (discriminated union) parameter is missing its discriminator field, or that field is not a string.
  • Fixes int64_string and decimal_string fields inside arrays not being coerced in either direction.

• #2124 Add new EventNotificationHandler class for better thin event management

  • We've been putting a lot of time into rethinking the event handling experience in the SDKs. This new class is the culmination of that effort.
  • They're designed for a tight coupling with both StripeClient and the fully-typed nature of thin events. This delivers painless event destination upgrades, in-editor checks for common mistakes, and better code modularity.
  • Now that we've released thin event notifications for v1 objects, these new handlers are our recommended path for all integrations using thin event notifications.
  • See more detailed docs here: https://docs.stripe.com/webhooks/event-notification-handlers
