OPEX v1.11.3: a big release for builders 🛠️

Overview

This release emphasizes API expansion, roughly doubling what users can automate through the OPEX Public API. The update introduces deposit receipting, editable purchaser information, and structured lot addresses for real estate workflows, plus document input fields for business e-signing.

OPEX for Real Estate

New

• Receipting deposits: Record deposit payments directly against contracts with payment method, trust account, and optional supporting file attachments.
• Share deposit receipts: Generate share links to quickly email receipt details to relevant parties.
• Edit purchaser on exchanged contract: Correct purchaser name details post-exchange without running the nomination process.
• Structured lot addresses: Store addresses as individual fields (line, suburb/city, state, postcode) instead of single strings for cleaner data integration.
• Contract summary refresh: Updated interface to surface deposit receipting activity.

OPEX for Business

New

• Document input fields: Add mandatory or optional text input fields to documents, assigned to specific signing parties for collecting targeted information during signing.
