A CLI and SDK to develop, build, and publish applications that extend Twenty CRM.

• Type‑safe client and workspace entity typings
• Built‑in CLI for auth, generate, dev sync, one‑off sync, and uninstall
• Works great with the scaffolder: create-twenty-app

Prerequisites

• Node.js 24+ (recommended) and Yarn 4
• A Twenty workspace and an API key. Generate one at https://app.twenty.com/settings/api-webhooks

Installation

npm install twenty-sdk
# or
yarn add twenty-sdk

Getting started

You can either scaffold a new app or add the SDK to an existing one.

• Start new (recommended):

  npx create-twenty-app@latest my-twenty-app
  cd my-twenty-app

• Existing project: install the SDK as shown above, then use the CLI below.

CLI quickstart

# Authenticate using your API key (CLI will prompt for it)
twenty auth login

# Add a new entity to your application (guided prompts)
twenty app add

# Generate a typed Twenty client and TypeScript definitions for your workspace entities
twenty app generate

# Start dev mode: automatically syncs changes to your workspace for instant testing
twenty app dev

# One‑time sync of local changes
twenty app sync

# Uninstall the application from the current workspace
twenty app uninstall

Usage (SDK)

// Example: import what you need from the SDK
import { /* your exports */ } from 'twenty-sdk';

Publish your application

Applications are currently stored in twenty/packages/twenty-apps.

You can share your application with all Twenty users:

# pull the Twenty project
git clone https://github.com/twentyhq/twenty.git
cd twenty

# create a new branch
git checkout -b feature/my-awesome-app

• Copy your app folder into twenty/packages/twenty-apps.
• Commit your changes and open a pull request on https://github.com/twentyhq/twenty

git commit -m "Add new application"
git push

Our team reviews contributions for quality, security, and reusability.

Troubleshooting

• Auth errors: run twenty auth login again and ensure the API key has the required permissions.
• Typings out of date: run twenty app generate to refresh the client and types.
• Not seeing changes in dev: make sure dev mode is running (twenty app dev).
