  packages: packages,
  restaurant_package_id: 1,
  adult: 2,
  kids: 1,
  price_cents: 1000,
  date: Date.today
  use_dynamic_pricing: true,
  custom_price_cents: 1500,
  group_sections: group_sections
)
builder.build

                                   promo_price, spending_tier_discount, selected_package)
end

#extract_spending_tier ⇒ Hash?

Extract DIY spending tier information from the selected packages. This method returns the spending tier data that was previously included in each package response. The spending tier provides information about spending thresholds and discount percentages for DIY packages, which is now returned as a separate attribute in the API response. The structure is flattened to include the appropriate tier data directly based on total price.

Examples:

{
  spending_type: 'per_booking',
  discount_type: 'percentage',
  name: 'Spending Incentive Tier 2',  # Selected based on total price
  price: { price: 150, price_cents: 15000, currency: 'THB', format: '฿150' },
  discount_percent: '5.0'
}

Returns:

  • (Hash, nil) —

    A hash containing the flattened spending tier details or nil if not applicable
