Supergood | Hemlane API
Programmatically access Hemlane rental property data, tenants and leases, rent payments, and maintenance workflows with a stable REST API. Supergood builds and operates production-grade, unofficial Hemlane integrations so your team can automate portfolio operations without heavy custom engineering.
Plain English: Hemlane is a property management platform for rental real estate that helps landlords and managers market listings, screen applicants, sign leases, collect rent, and coordinate maintenance with tenants and local service pros. An unofficial API lets you pull properties, units, tenants, leases, rent rolls, payment ledgers, and maintenance requests—and push updates like new service tickets or unit/lease changes back into Hemlane.
For a tech company integrating with Hemlane, this means you can ingest real-time portfolio and financial data to power dashboards, sync rent payments and fees to accounting (e.g., QuickBooks, Xero), automate maintenance triage, trigger delinquency alerts and reminders, or enrich your platform with lease and tenant context. You can also streamline showing workflows, centralize documents, and keep downstream systems (ERP, analytics, CRM, support) in sync.
Some teams report challenges around direct integrations with Hemlane—such as lack of a public API, reliance on manual CSV exports for accounting, limited webhook/event support for payments and maintenance updates, and friction when trying to automate tasks that are optimized for portal use. An unofficial API can reduce this operational drag by providing stable, programmatic access to the same data and actions you use every day in the UI.
What is Hemlane?
Hemlane (https://www.hemlane.com/) is a cloud platform for residential rental property management. It centralizes leasing, tenant communication, rent collection, accounting workflows, and maintenance coordination across owners, managers/agents, tenants, and vendors. Teams use Hemlane to advertise listings, manage inquiries and showings, screen applicants, execute leases with e-signatures, collect rent and deposits, assess late fees, coordinate repairs with local pros, and manage documents—all with tenant and owner portals for collaboration.
Core product areas include:
- Leasing & Marketing (Listings, Lead Tracking, Applications, Screening, Showings, E-Signatures)
- Rent Collection & Financials (Recurring Charges, One-Time Fees, Payments, Payouts, Refunds, Late Fees, Ledger/Reports)
- Tenant & Lease Management (Tenants, Leases, Co-signers, Notices, Documents)
- Maintenance (Tickets/Requests, Work Orders, Vendor Assignment, Messaging, Photos/Docs)
- Communications & Tasks (Messaging, Announcements, Reminders, Tasks/Follow-ups)
Common data entities:
- Users and Roles (Owner, Manager/Agent, Tenant, Vendor/Service Pro)
- Properties and Units (addresses, attributes, market/occupancy status)
- Tenants and Applicants (contacts, application status, screening results)
- Leases (terms, rent schedule, deposits, proration, status)
- Payments (charges, invoices, ACH/card payments, fees, refunds, payout status)
- Maintenance Requests (category, priority, SLA/status, assignments, attachments)
- Documents (leases, addenda, receipts, inspection photos)
The Hemlane Integration Challenge
Property management teams depend on Hemlane daily, but turning portal-first workflows into API-driven automation is non-trivial:
- Role-aware portals: Owners, managers, tenants, and vendors see different data, actions, and approval states
- Financial rigor: Recurring rent, partial payments, late fees, and ACH/card differences require consistent modeling
- Portal-first flows: Applications, screening, lease e-signature, and maintenance coordination are optimized for the UI
- Authentication complexity: SSO/MFA and session lifecycle management complicate headless automation
- Data spread: Key objects span listings/leasing, payments/ledgers, and maintenance with context across multiple views
How Supergood Creates Hemlane APIs
Supergood reverse-engineers authenticated browser flows and network interactions to deliver a resilient API endpoint layer for your Hemlane tenant.
- Handles username/password, SSO/OAuth, and MFA (SMS, email, TOTP) securely
- Maintains session continuity with automated refresh and change detection
- Normalizes responses so you can integrate once and rely on consistent objects across modules
- Aligns with customer entitlements and role-based permissions to ensure compliant access

Frequently Asked Questions
Q: Which Hemlane modules can this integration cover?
Supergood supports workflows across commonly used modules such as Leasing (Listings, Applications), Tenant/Lease Management, Rent Collection (charges, payments, payouts), and Maintenance (tickets, vendor assignments), subject to your licensing and entitlements. We scope coverage during integration assessment.
Q: How are MFA and SSO handled for automation?
We support username/password + MFA (SMS, email, TOTP) and can operate behind SSO/OAuth when enabled. Sessions are refreshed automatically with secure challenge handling.
Q: Can you sync payments and fees to our accounting system?
Yes. We can normalize rent, fees, methods (ACH/card), and payout states to match your accounting schema and deliver updates via webhooks or polling while complying with rate and permission constraints. We commonly integrate with QuickBooks and Xero.
Q: Do you support maintenance attachments and vendor notifications?
Yes. We support uploading attachments via signed uploads with checksum validation, returning time-limited URLs. Vendor assignments, status changes, and tenant notifications are modeled explicitly in our normalized responses.
