OpenAPI Specification
openapi: 3.2.0
info:
title: Lawmatics OAuth Custom Emails API
version: 1.22.0
description: 'The official Lawmatics REST API for legal CRM, client intake and law firm automation. Manage matters (prospects), contacts, companies, custom forms and form entries, custom fields, events and appointments, tasks, notes, files, tags, users, time entries, expenses, invoices and transactions.
Authentication is OAuth 2.0 authorization code grant; access tokens do not expire, there are no refresh tokens, and Lawmatics does not currently support scopes - an authorized app receives full CRUD access to the granted account.
All list endpoints support the shared query-parameter grammar documented in the Param Guide: `fields` (field selection, one level deep, `fields=all` to expand), `page` (pagination), `sort_by`/`sort_order`, and `filter_by`/`filter_on`/`filter_with` (one filter at a time; operators `=`, `!=`, `<=`, `<`, `>=`, `>`, `like`, `ilike`, `null`, `not_null`).
Responses follow a JSON:API-style `data` / `attributes` / `relationships` envelope.'

note: 'NOT published by Lawmatics. Lawmatics publishes no OpenAPI. Every path, method, parameter, request example and response example in this document was converted mechanically from the provider-published Postman collection "Lawmatics OAuth API v1.22.0"; nothing was invented. Schemas are typed as generic objects because the collection carries examples, not JSON Schema. The server URL is the base documented in the collection Param Guide (https://api.lawmatics.com), not the collection''s disabled {{host}} placeholder. The 401 and 429 responses added to every authenticated operation are the provider-documented, globally applicable responses: the collection''s auth guide states a per-firm rate limit applies to all endpoints and returns 429 with a Retry-After header, and https://api.lawmatics.com/v1/contacts was observed returning 401 unauthenticated on 2026-08-13.'
