ProMax API
ProMax is an all-in-one front-end retail platform for automotive dealerships, combining CRM, desking, credit, compliance, inventory, and data mining into a single "credit-driven retailing" workflow. An unofficial API lets you pull leads and customers, deal structures, inventory, lender and compliance results, and data-mining outputs—and push new leads, updated deals, appraisals, and forms back into ProMax.
What is ProMax?
ProMax is an all-in-one front-end software platform for automotive dealerships, built around what the company calls "credit-driven retailing." ProMax Complete consolidates CRM, desking, credit, compliance, inventory, and data mining into a single connected workflow, so dealership teams structure deals, screen customers, and manage leads from one system rather than stitching together point tools.
Core product areas include:
- Complete CRM (lead generation, call tracking, marketing, and a mobile app)
- Desking with Lender Select (deal structuring and dealer reserve across multiple lenders)
- Credit and Compliance (Red Flag alerts, OFAC and MLA screening, automated FTC compliance)
- Inventory management and Appraisal Express
- Data Mining for equity and conquest opportunities in the existing customer base
- ID Verification and Fraud Detection, Employment & Income Verification, and Forms with e-signature
Common data entities:
- Leads, Customers, Up logs, Tasks, and Communications
- Deals, Desking scenarios, Lender quotes, and Dealer Reserve
- Vehicles, Inventory, Appraisals, and Trade valuations
- Compliance results (Red Flag, OFAC, MLA), Credit pulls, and Verifications
- Forms, E-signatures, and Documents
The ProMax Integration Challenge
Dealerships run high-volume sales workflows on ProMax every day, but turning portal-driven desking and CRM activity into API-driven automation is non-trivial:
- Partner-gated access: ProMax exposes a Data Exchange API, but custom integrations typically run through partnership and certification rather than self-serve developer keys
- Dealer-by-dealer configuration: Lender setups, compliance rules, forms, and deal templates vary per store and rooftop—generic integrations break across dealers
- Tightly coupled modules: CRM, Desking, Credit, and Compliance share state, so deal and customer data must stay consistent across all of them
- Sensitive credit and compliance data: Credit pulls, OFAC/MLA screens, and Red Flag results carry regulatory weight and demand careful, audited handling
- Mobile and web split: Reps work from both the ProMax mobile app and the web platform, so automation must reach data that surfaces across both
- Authentication complexity: Dealer logins, role-based access, and session timeouts complicate headless, always-on automation

Supergood reverse-engineers ProMax's authenticated browser flows and Data Exchange surfaces to deliver a resilient API layer for your dealership's ProMax instance—covering CRM, desking, inventory, and compliance data together.
- Handles dealer username/password and MFA securely in a managed session
- Maintains session continuity with automated refresh and change detection
- Normalizes responses across Leads, Deals, Inventory, and Compliance so you integrate once and rely on consistent objects
- Aligns with each dealer's lender setup, compliance rules, and form templates to keep access accurate and compliant

Frequently asked questions
Yes. Where your dealership has Data Exchange API access enabled, Supergood uses it directly, and supplements it with authenticated flows to cover CRM, desking, and compliance data the API doesn't expose.
No. Supergood works with your existing ProMax dealer credentials and entitlements. You don't need to become a certified integration partner to pull or push your own data.
Yes. Deal structures, lender quotes, and Lender Select dealer reserve are exposed through the same normalized API surface, so pricing and reporting tools can consume them programmatically.
Credit pulls, OFAC/MLA screens, and Red Flag results are handled with encrypted credential storage, scoped access, and audit logging, preserving the dealer's regulatory controls rather than forcing a generic schema.
Yes. Supergood profiles each store's lender setup, compliance rules, and form templates, so multi-rooftop dealer groups get consistent, per-store-accurate access across all locations.
