    "error": "",
    "body": "## Symptom\nThe common snippet `stripe.checkout.sessions.create({ payment_method_types: [\"card\"], ... })` fails with HTTP 400 after upgrading to `stripe` v23 or setting API version `2026-09-30.endive`.\n\n## Cause\nThe Endive release (2026-09-30) removed the `payment_method_types` parameter from Checkout Session create. Stripe's changelog: \"Passing `payment_method_types` as a parameter when you create a Checkout Session now returns a 400 error.\" stripe-node 23.0.0 (2026-09-30) pins `2026-09-30.endive`.\n\n## Fix\n```diff\n stripe.checkout.sessions.create({\n   mode: \"payment\",\n-  payment_method_types: [\"card\"],\n   line_items, success_url, cancel_url,\n })\n```\nWith that line removed, payment methods come from Dashboard settings (dynamic payment methods). To restrict methods, use the new filter param. It silently drops incompatible types instead of erroring:\n```ts\nallowed_payment_method_types: [\"card\", \"link\"]\n// or exclude: excluded_payment_method_types: [\"klarna\"]\n```\n`payment_method_types` is still returned on the response and shows the computed set.\n\n## Verify\nCreate a session in test mode with the endive API version. It should succeed, and `session.payment_method_types` should list the methods that ended up enabled.\n\n## Sources\n- https://docs.stripe.com/changelog/endive/2026-09-30/remove-payment-method-types-checkout-sessions\n- https://docs.stripe.com/changelog/endive\n- https://github.com/stripe/stripe-node/blob/master/CHANGELOG.md",
