Connectors Overview

2 min readLast updated Sep 9, 2026

Connectors are open-source reference integrations built on the platform’s surfaces — they subscribe to webhooks and call the REST API to connect Efimis with the tools your firm already uses. Each one is a working, deployable codebase you can run as-is or fork as the starting point for your own integration.

Connector What it does
NetDocuments Syncs Efimis clients and matters to NetDocuments custom properties, and profiles and uploads documents written against them.
iManage Syncs Efimis clients and matters to iManage Work custom properties, and profiles and uploads documents written against them.
Zapier A self-managed Zapier integration with an Efimis webhook event trigger, client and matter searches, matter actions, and dynamic dropdowns.
Power Automate Automate Efimis workflows from Microsoft Power Automate.

Connectors are not an additional API surface — they are clients of the existing ones. Reading their source is a practical way to see the six surfaces used together in production-shaped code: OAuth 2.0 client credentials for authentication, webhook subscriptions with HMAC-SHA256 signature verification for events, and REST calls for reads and writes.
