Programmatically access Thomson Reuters Legal Tracker’s corporate legal datasets—matters, invoices (LEDES), accruals, budgets, law firms/timekeepers—and workflow tools via a stable REST API. Supergood builds and operates production-grade, unofficial Legal Tracker integrations so your team can automate matter sync, e‑billing, approvals, and spend reporting without heavy custom engineering.

Thomson Reuters Legal Tracker is software used by corporate legal departments to manage matters and outside counsel spend. With an unofficial API, you can sync matters and custom fields, retrieve and normalize invoices and LEDES line items, capture accruals from law firms, push approvals and routing decisions, and export audit-ready artifacts—directly inside your legal ops and finance systems.

If you’re a legal tech company integrating Legal Tracker, you can pull matter and invoice data into case management, push new matters and budgets, collect firm accruals programmatically, and align rate cards and UTBMS coding. You can also build features like automated invoice compliance checks, spend dashboards, firm scorecards, and workflow automations that bridge legal ops with ERP/AP, procurement, and BI tools.

Legal Tracker (formerly Serengeti Tracker) is an Enterprise Legal Management (ELM) platform for corporate legal departments. It powers matter management, e‑billing and LEDES validation, outside counsel guidelines enforcement, accrual and budget tracking, law firm and timekeeper rate management, and reporting.

Core product families include:

  • Matter Management (intake, tracking, custom fields, phases/tasks)
  • E‑Billing & Spend Management (LEDES validation, approvals, adjustments)
  • Accruals & Budgets (forecasting, period tracking, variance reporting)
  • Vendor & Timekeeper Management (firm onboarding, rate cards, roles)
  • Compliance & Audit (OCG enforcement, audit trails, retention)

Common data entities:

  • Matters (number, title, status, custom fields, practice area, business unit)
  • Invoices (header and LEDES line items, taxes/adjustments, compliance flags)
  • Firms and Timekeepers (roles, rate cards, effective dates, currencies)
  • Accruals and Budgets (period start/end, amounts, variance, notes)
  • Approvals and Workflows (queues, actions, comments, timestamps)
  • Documents and Notes (attachments, guidelines, evidence)

Legal ops teams rely on Legal Tracker daily, but taking portal-centric workflows and making them API-driven is hard. Common pain points we hear from customers:

  • Limited real-time API access: Many accounts primarily use reports/SFTP exports; public APIs may be restricted or vary by licensing
  • Portal-first experiences: Matter intake, rate cards, and accrual capture live in the web app, slowing automation
  • Complex enterprise security: SSO/MFA and network controls complicate headless session management
  • E‑billing constraints: LEDES/UTBMS validations differ by OCG; error codes and line‑item adjustments require normalization
  • Custom fields and configuration drift: Account-specific fields and workflows make consistent schemas challenging
  • Attachments and artifacts: Retrieving invoice PDFs, LEDES files, and supporting documents programmatically isn’t straightforward

Supergood reverse‑engineers authenticated browser flows and network interactions to deliver a resilient API endpoint layer for your Legal Tracker workflows.

  • Handles username/password, SSO/OAuth, and MFA (SMS, email, TOTP) securely
  • Maintains session continuity with automated refresh and change detection
  • Normalizes responses (matters, invoices, accruals, rates) into consistent objects
  • Aligns with customer entitlements and licensing constraints to ensure compliant access

Frequently Asked Questions

Supergood supports workflows across matter management, e‑billing, accruals/budgets, and firm/timekeeper management, 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 we submit accruals or create matters programmatically?

Yes. Accruals and matter intake can be pushed via API, with normalization to your account’s custom fields and guidelines while complying with rate and licensing constraints.

Q: How do you normalize LEDES/UTBMS invoices and compliance flags?

We standardize line‑item schemas (task/activity, hours, rate, amount), timekeeper roles, and compliance flags into consistent objects, including error codes and suggested adjustments, so your downstream systems don’t need to handle account‑specific variations.

Supergood can have your Legal Tracker integration live in days with no ongoing engineering maintenance.
