Read/Write API

The Open Law Read/Write API is the secured resource layer for practice data — matters, parties, documents, financials, scheduling, and related profiles — protected with FAPI 2.0 patterns (including PAR and PKCE where required).

What it exposes

Resource APIs are organised by conformance profiles, including:

• Authorisations and consent-linked access
• Parties and matters
• Documents
• Financials / invoices
• Scheduling

Exact paths and schemas are defined in the read-write-api repository and the shared specification ontology.

Security expectations

• Client consent at the firm TSP
• Client-tier scopes and client-visible data boundaries
• Token lifecycle aligned with FAPI

For app builders

You may call firm TSP endpoints directly after DCR and consent, or use a commercial connectivity layer such as Mattertwo Connect that normalises multi-firm access.
