Supergood | DealerCenter DMS API

Programmatically access DealerCenter DMS inventory, CRM, desking, and BHPH data with a stable REST API. Supergood builds and operates production-grade, unofficial DealerCenter integrations so your team can automate dealership workflows without heavy custom engineering.

Plain English: DealerCenter is dealer management software used by independent and franchise car dealerships to manage inventory, acquire leads, desk deals, submit credit apps, and service BHPH accounts. An unofficial API lets you programmatically pull vehicles, photos, book values, leads/customers, deals and lender statuses, BHPH accounts and payments—and push new leads, quotes, credit apps, and payments back into DealerCenter.

For a tech company selling to car dealerships, this means you can sync real-time inventory and pricing to power storefronts, capture leads from your digital retail experiences, create/price deals with taxes and fees, submit credit applications to lenders, and mirror BHPH accounts to automate reminders and reconciliation. You can also push photos/documents, update statuses across systems (CRM, analytics, accounting), and keep multi-rooftop operations in lockstep.

What is DealerCenter?

DealerCenter (https://www.dealercenter.com/) is a cloud dealer management system (DMS) that centralizes sales, inventory, F&I, websites/digital retail, and buy-here-pay-here servicing for automotive retailers. Teams use DealerCenter to merchandise vehicles, capture and work leads, desk and contract deals, submit credit apps to lenders, manage documents and compliance, and collect BHPH payments.

Core product areas include:

  • Inventory & Merchandising (VIN decode, pricing, photos, reconditioning, syndication)
  • CRM & Lead Management (website leads, third-party marketplace leads, tasks, appointments)
  • Desking & F&I (quotes, taxes/fees, trade-ins, lender submissions, e-contracting)
  • Digital Retailing & Websites (online checkout, credit apps, pre-qualification)
  • BHPH & Collections (loan setup, payment schedules, receipts, delinquency workflows)
  • Documents & Compliance (forms, e-sign, OFAC/Red Flags, stips)
  • Vendor & Accounting Integrations (e.g., QuickBooks, book values, floorplan)

Common data entities:

  • Dealerships, Users, Roles, and Permissions
  • Vehicles (VIN, stock, photos, cost, price, book values, reconditioning)
  • Leads and Customers (contact data, consent, source, assignments)
  • Deals/Quotes (vehicle, buyer/co-buyer, trade-in, taxes/fees, payments)
  • Credit Applications and Lender Decisions (bureau pulls, status, stip requests)
  • BHPH Accounts (amortization schedules, payment history, late fees)
  • Payments & Receipts (method, amounts, posting, allocation)
  • Documents & Attachments (forms, IDs, stips, photos)

The DealerCenter Integration Challenge

Dealers live in DealerCenter, but turning portal-first workflows into reliable automation is hard:

  • Module-specific UX and entitlements across Inventory, CRM, F&I, and BHPH
  • Multi-rooftop complexity: lots, locations, pricing strategies, and photo pipelines
  • Lender flows and statuses vary by program; strict compliance and audit trails apply
  • Data spread across dashboards, exports, and document attachments not built for APIs
  • Authentication with MFA/SSO and session expiry complicates headless access

How Supergood Creates DealerCenter APIs

Supergood reverse-engineers authenticated browser flows and network interactions to deliver a resilient API endpoint layer for your DealerCenter 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 dealership entitlements and role-based permissions to ensure compliant access
