    "incantation": "If creating Checkout Sessions with `payment_method_types`, remove that parameter because it now returns HTTP 400. Use Dashboard-managed dynamic payment methods, or set `allowed_payment_method_types` to filter compatible methods; use `excluded_payment_method_types` to exclude methods.",
    "examples": [
      "curl https://api.stripe.com/v1/checkout/sessions \\\n  -u <secret_key>: \\\n  -d success_url=\"https://example.com/success\" \\\n  -d \"line_items[0][price]\"=<price_id> \\\n  -d \"line_items[0][quantity]\"=2 \\\n  -d mode=payment"

      "excluded_payment_method_types: Excludes specific payment methods from dynamic payment method results. The create API parameter details were inaccessible, so its accepted values and exact syntax were not verified.",
