Step-by-Step State Machine Transition for Escrow Releases
# app/services/sharetribe_escrow_service.rb
class SharetribeEscrowService
def self.release_vendor_payout!(transaction_id)
tx = SharetribeIntegrationApi.fetch_transaction(transaction_id)
return unless tx.state == 'delivered_confirmed'
# Calculate platform commission (12%) and net vendor payout
total_amount = tx.total_cents
platform_fee = (total_amount * 0.12).round
vendor_payout = total_amount - platform_fee
# Execute Stripe Connect transfer to vendor connected account
Stripe::Transfer.create({
amount: vendor_payout,
currency: tx.currency,
destination: tx.vendor_stripe_account_id,
source_transaction: tx.stripe_charge_id,
description: "Vendor payout for Sharetribe order " + transaction_id.to_s
})
# Transition Sharetribe transaction state
SharetribeIntegrationApi.transition_transaction(transaction_id, 'payout_completed')
