Relativity API
Relativity is an AI-powered legal data software company whose flagship platform, RelativityOne, helps legal teams organize complex data, uncover what matters most, and act with confidence. This page is an independent design exercise that asks what a well-designed Relativity 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 Relativity 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 Relativity 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 Relativity?
Relativity is an AI-powered legal data software company whose flagship platform, RelativityOne, helps legal teams organize complex data, uncover what matters most, and act with confidence. Law firms, corporations, and government agencies use Relativity for e-discovery, legal hold, early case assessment, investigations, contract review, and data breach response, collecting from sources like Microsoft 365, Google Workspace, and Slack, then processing, reviewing, and producing documents inside a single cloud workspace.
Core product areas include:
- RelativityOne (cloud e-discovery: legal hold, collection, processing, review, production, early case assessment)
- Relativity aiR (generative AI: aiR for Review, aiR for Privilege, aiR for Case Strategy, aiR for Data Breach Response)
- Review Center (customizable review queues and workflows)
- RelativityOne Government (FedRAMP-authorized variant for public-sector agencies)
- Relativity App Hub and Relativity MCP (custom apps and AI-agent connectivity)
An API for a platform like this would naturally organize around its core data entities:
- Workspaces, Matters, Clients, Users, Groups
- Documents, Images, Native files, Metadata, Fields
- Saved Searches, Search Indexes, Conditions, Views
- Productions, Production Sets, Markups, Redactions
- Legal Holds, Custodians, Collections, Preservation Notices
- Relativity Dynamic Objects (RDOs), Coding Decisions, Batches, Tags
The Relativity Integration Challenge
Legal teams run case-defining workloads on Relativity daily, but turning workspace- and review-driven workflows into API-driven automation is non-trivial:
- Per-workspace customization: Fields, layouts, coding panes, and RDOs are configured per matter, generic integrations break across workspaces and tenants
- Object Manager indirection: Querying documents, fields, and RDOs requires resolving Artifact IDs, ObjectType integers, and condition syntax rather than simple resource paths
- Import/Export pipeline complexity: Bulk document, image, and RDO loads operate on load files and staged workspace locations, not single REST writes
- Authentication and partner gates: SSO, OAuth, and MFA are standard in legal environments, and full platform access can sit behind RelativityOne partner and entitlement controls
- Versioned API surface: Endpoint coverage and behavior differ across RelativityOne releases and the FedRAMP-authorized Government variant
- Chain-of-custody and audit requirements: Productions, redactions, and coding decisions demand precise, defensible audit trails
What a Relativity API Could Look Like
If Relativity 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 endpoint sketches, technical requirements, and use cases below flesh out this hypothetical design.

Potential API Endpoints
Authentication
/authenticateWould authenticate to a Relativity environment using SSO, OAuth, or MFA and obtain a session token for downstream calls.
Workspaces
/workspacesWould list workspaces (matters) with filters for client, status, and creation date across the Relativity instance.
Documents
/documentsWould query documents, fields, and metadata within a workspace using saved searches and condition filters via Object Manager.
Documents
/import_documentsWould import documents, images, natives, and Relativity Dynamic Objects into a workspace from load files via the Import service.
Productions
/productionsWould retrieve production sets, markups, and redactions with status and date-range filters.
Legal Holds
/create_legal_holdWould create a legal hold, assign custodians, and issue preservation notices for a matter.
Use Cases
Sync e-discovery documents and metadata into a warehouse
- Pull documents, fields, and coding decisions from review workspaces into a single warehouse - Stream search results and batch status to downstream analytics and reporting tools - Reconcile custodian and collection records across matters for unified case 360
Automate document import and review coding
- Push documents, images, and RDOs into a workspace from upstream collection tools via load files - Apply coding decisions and tags programmatically without manual review-pane clicks - Route privilege and responsiveness calls to downstream QC and case-strategy workflows
Orchestrate productions and redactions
- Pull production sets, markups, and redactions for delivery tracking and chain-of-custody logging - Trigger production generation and validate Bates ranges before export - Surface production errors and stamping issues to case-management workflows
Keep legal hold and custodian data in sync
- Create legal holds and issue preservation notices when a matter is opened - Pull custodian acknowledgement and collection status for compliance reporting - Trigger downstream HR and IT workflows when custodian or hold scope changes
Connect via No-Code Tools
Automate this platform from the no-code stack you already use.
Technical Requirements
Authentication
Would require SSO, OAuth, and MFA (SMS, email, TOTP) with managed session handling
Connectivity
Would build on authenticated browser flows plus Relativity Object Manager, Import/Export, and Workspace REST services where exposed
Response format
Normalized JSON across Workspace, Document, Search, Production, and Legal Hold objects
Rate limits
Adaptive throttling tuned to your RelativityOne tenant to avoid platform-side limits
Session management
Would need automatic session refresh, MFA replay handling, and credential rotation
Data freshness
Near real-time pulls for documents, searches, and productions with optional scheduled batch syncs
Security
Encrypted credential vault, scoped access tokens, SOC 2-aligned controls, and audit logging; FedRAMP-aware for Government tenants
Webhooks
Event-style callbacks for document import completion, production status, and legal hold acknowledgements
Latency
Design target: sub-second reads on cached entities; multi-second writes when importing documents and generating productions
Throughput
Design target: horizontally scaled workers sized to large-volume document and metadata loads
Reliability
Retry, backoff, and idempotency keys for imports, coding updates, and production transactions
Versioning
Clear versioning and change management would matter as Relativity evolves
Frequently asked questions
Production sets, markups, and redactions are exposed through the normalized API with defensible chain-of-custody logging, so every read and write is captured for audit and discovery purposes.
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.
