Lawmatics is a legal CRM, client-intake and marketing-automation platform for law firms, from solo practices to multi-office firms. Its public developer surface is the Lawmatics OAuth API — a REST API of 177 operations across matters (called prospects in the API), contacts, companies, custom intake forms and form entries, custom fields, collections, pipelines, stages, practice areas, marketing sources and campaigns, events, tasks, notes, files, tags, users, time entries, expenses, invoices and transactions — plus a set of signed outbound webhooks. Access is OAuth 2.0 authorization code, gated on a Lawmatics support representative enabling developer settings on the account, and the resulting access token is non-expiring, unscoped and grants full CRUD over the firm.
Lawmatics publishes 27 APIs on the APIs.io network, including Addresses API, Collections API, Companies API, and 24 more. Tagged areas include Legal, CRM, Law Firms, Client Intake, and Marketing Automation.
The Lawmatics catalog on APIs.io includes 1 event-driven AsyncAPI specification and 1 JSON-LD context.
Lawmatics’ developer surface includes authentication, changelog, documentation, API reference, getting-started guide, support, engineering blog, and 28 more developer resources.
Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it
carries 10 points of the composite. It is scored from the published contracts
themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already
holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in
front of it, and the first time that check is skipped a duplicate record is created.
Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet,
not penalised by it.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/lawmatics: open an issue to ask a question, or submit a pull request to add artifacts.

x-pointers-deliberately-absent:
MCPServer: mcp/lawmatics-mcp.yml exists but records deployment mode "none" — Lawmatics ships no MCP server, hosted or stdio.
The file is an API Evangelist candidate tool list derived from the OpenAPI. Wiring MCPServer would assert an agent surface
that does not exist.
WellKnown: well-known/lawmatics-well-known.yml records 36 probes across 4 hosts and zero documents. The file documents an
absence, not a served surface.
SecurityTxt: /.well-known/security.txt returns 404 on every Lawmatics host.
AgentCard: /.well-known/agent-card.json and /.well-known/agent.json return 404 (or 403 on the S3-fronted app host) on every
Lawmatics host. Nothing was written to a2a/ — an agent card is never authored on a provider's behalf.
Security: probe-security-programs.py found no vulnerability-disclosure policy, no security@ contact and no bug-bounty program
on 2026-08-13.
TrustCenter: no trust centre, no report portal and no subprocessor list. Certifications are published as prose on the marketing
security page, which is wired as Compliance.
Idempotency: the Lawmatics REST API documents no idempotency key on any of its 177 operations. The only idempotency in the
platform is consumer-side de-duplication of webhook deliveries on event_id, which is not an idempotency contract on writes.
SDKs: Lawmatics publishes no first-party API client library in any language.
AsyncAPI: webhooks are documented in prose only; no AsyncAPI document is published.
Sandbox: no sandbox, test mode or test credentials exist.
Deprecation: no deprecation policy, notice period or Sunset header support is published.
