Developers

Build on top of BusinessHRM. This section is for company administrators and developers who want to connect BusinessHRM to other tools, automate workflows, or let AI assistants read and write your workspace data.

There are two ways to integrate:

REST API — a standard JSON HTTP API at https://app.businesshrm.com/api/v1, authenticated with an API key. Use it from scripts, automations (Zapier, Make, n8n), or your own apps.
MCP (Model Context Protocol) — connect AI assistants such as Claude, Cursor and ChatGPT directly to your workspace so they can work with your contacts, tasks, projects, invoices and more.

Getting Started with the API — overview of the REST API and the interactive documentation.
API Keys — create, scope, rotate and revoke the keys that authenticate your requests.
REST API Basics — base URL, authentication, pagination, fields, sorting, filtering and error codes.
Connect MCP with Claude and other AI assistants — connect Claude Desktop, Claude.ai, Cursor and ChatGPT via MCP.

Permission: API key management is available to App Administrators only. Anyone with a valid API key (or who completes the MCP sign-in) can call the API, but each key acts on behalf of the user who created it and is limited to that user's workspace and permissions.
