Aderant API
Aderant provides practice management and financial systems for law firms, including Aderant Expert and Expert Sierra (cloud), plus products like iTimekeep (time capture), BillBlast (eBilling), CompuLaw (docketing/calendaring), Handshake (knowledge/intranet), and OCG Live (guideline enforcement). This page is an independent design exercise that asks what a well-designed Aderant API could look like: the resources it would expose, the authentication it would need, and the workflows it could unlock. Below: a hypothetical endpoint design, the technical requirements a production implementation would face, the use cases programmatic access could serve, and where to start if your team needs this kind of access today.
This page is an independent analysis by Supergood of what a well-designed Aderant API could look like. It draws on publicly available information, vendor materials, and general integration experience in this category. Nothing on this page describes an existing Aderant product, and Supergood is not affiliated with or endorsed by the vendor. If the vendor offers an official API, we highly recommend it.
What is Aderant?
Aderant provides practice management and financial systems for law firms, including Aderant Expert and Expert Sierra (cloud), plus products like iTimekeep (time capture), BillBlast (eBilling), CompuLaw (docketing/calendaring), Handshake (knowledge/intranet), and OCG Live (guideline enforcement). Firms rely on Aderant to handle timekeeping, matter and client records, billing and eBilling, trust and AR, conflicts and intake, docketing, reporting, and role-based approvals.
Core product areas include:
- Timekeeping & Rates (time/expense capture, rate tables, alternative fee arrangements)
- Matter & Client Management (intake, conflicts, client/matter hierarchies, assignments)
- Billing & eBilling (prebills, narratives, write-ups/downs, LEDES files, BillBlast submission)
- OCG Management (policy rules, validations, exception routing)
- Docketing & Calendaring (rules-based court deadlines via CompuLaw)
- Trust, AR & Collections (trust balances, receipts, write-offs, payment application)
- Reporting & Analytics (WIP/AR dashboards, utilization, realization)
- Knowledge & Integrations (Handshake portals, iManage/SharePoint links)
An API for a platform like this would naturally organize around its core data entities:
- Clients & Contacts (client number, billing addresses, payors)
- Matters (matter number, titles, responsible partners, practice groups, phases/tasks)
- Timekeepers/Users (attorneys, paralegals, roles, rates)
- Rates & Rate Cards (standard, client/matter negotiated, timekeeper-specific)
- Time & Expense Entries (date, hours/amount, UTBMS codes, narratives, status)
- Prebills & Invoices (line items, adjustments, taxes, LEDES exports, statuses)
- eBilling Submissions (target vendor, file versions, acceptance/rejection)
- Payments & Trust (receipts, allocations, balances, transfers)
- OCG Rules (policy definitions, violations, exceptions)
- Approvals & Audit (who approved, when, changes)
The Aderant Integration Challenge
Legal finance data and workflows are robust, and integrating cleanly is non-trivial:
- Multi-environment variability: Expert on-prem vs Expert Sierra, custom fields via Designer, regional ledgers, and firm-specific workflows
- Prebill lifecycle: WIP, draft, routing, revisions, and finalization span days and require idempotent, auditable updates
- OCG nuance: Client-specific rules (activity/task codes, narratives, rates, caps) must be validated consistently to avoid eBilling rejections
- eBilling complexity: LEDES generation, BillBlast submissions, vendor acknowledgements, and rejection remediation are asynchronous
- Authentication & security: AD/MFA and session handling differ by firm; least-privilege and entitlement alignment are mandatory
- DMS context: iManage workspaces are often the primary attorney interface; mapping matter and document context is essential
- Audit rigor: Every post, edit, and approval needs traceability with before/after values and user attribution
What a Aderant API Could Look Like
If Aderant exposed a modern, general-purpose API, the integration challenges above suggest what it would need to get right. This is a design sketch, not documentation of anything that exists today:
- First-class authentication: session handling with support for MFA and enterprise sign-on where the platform uses them
- Consistent resources: normalized JSON schemas and pagination across the platform's core objects
- Reliable writes: idempotency keys and validation that mirrors the platform's own workflow rules
- Entitlement awareness: endpoints scoped to what each customer's licensing actually permits
The sections below flesh out this hypothetical design.

Need This Kind of Access Today?
If your team needs this kind of access today, Supergood builds integrations on request, one customer at a time. We act at the direction of our customers, within the access they already hold. Customers bring their own accounts, licenses, and entitlements. If the vendor offers an official API, we highly recommend it.
- Schedule an Integration Assessment
A 30-minute session to review your product mix, licensing, and authentication model. - Scope the Integration
We design the access pattern around your workflows and entitlements. - Deploy with Monitoring
Go live with continuous monitoring as your platforms evolve.
Use Cases
Time Capture From iManage
- Capture time against the active iManage document/workspace and post to the correct client/matter with UTBMS codes - Validate entries against OCGs pre-post, suggest compliant narratives, and flag exceptions - Auto-apply negotiated rates and calculate WIP amounts
Matter Finance Inside the DMS
- Show budgets, WIP, AR, and rate info inside iManage workspaces - Let users request rate exceptions or add matter notes that sync back to Aderant - Keep matter lists in sync across practice teams and deal rooms
Prebill Review & eBilling
- Pull prebills with line-level details for in-app redlines, write-ups/downs, and narrative edits - Attach invoice PDFs stored in iManage, generate LEDES, and submit via BillBlast - Track acceptance/rejection statuses and remediate with one-click corrections
Intake, Conflicts, and Approvals
- Start matter intake from your app, capture required fields, and route to approvers - Run conflicts via the firm’s process and sync the resulting matter to create an iManage workspace - Enforce approval gates before time or billing can proceed
Connect via No-Code Tools
Automate this platform from the no-code stack you already use.
Technical Requirements
Authentication
Would require username/password with MFA (SMS, email, TOTP); supports service accounts or customer-managed credentials
Connectivity
Would build on works with Expert on-prem (via secure connector/VPN) and Expert Sierra (cloud); honors firm network policies
Response format
JSON with consistent resource schemas and pagination across modules
Rate limits
Tuned for enterprise throughput while honoring customer entitlements and usage controls
Session management
Would need automatic reauth and cookie/session rotation with health checks
Data freshness
Near real-time retrieval of matters, time/WIP, prebills, invoices, and eBilling statuses
Security
Encrypted transport, scoped tokens, audit logging; respects Aderant role-based permissions and approval gates
Webhooks
Optional asynchronous delivery for long-running workflows (billing runs, eBilling accept/reject, trust receipts)
Latency
Design target: sub-second responses for list/detail queries; billing and eBilling operations reflect underlying platform timing
Throughput
Design target: designed for high-volume time capture and prebill synchronization across large matter portfolios
Reliability
Retry logic, backoff, and idempotency keys minimize duplicates and support at-least-once processing
Versioning
Clear versioning and change management would matter as Aderant evolves
Frequently asked questions
Availability of official interfaces varies by product, plan, and licensing. Many platforms in this category gate access behind partner programs or paid modules, and there is often no broadly available, self-serve public API. Check the vendor's developer resources for current offerings.
The hard parts would be authentication (MFA, session management, enterprise controls), consistent schemas across the platform's products, and write semantics that reconcile the way the platform's own workflows do.
