# Create a project.

POST https://services.leadconnectorhq.com/ai-builder-api/projects

Creates an app in the sub-account. Then start its first build with `POST .../agent-runs`; a sub-account token sends `externalAgent: true` because its own agent writes the code.

## Authentication

Send `Authorization: Bearer <token>` using:

- **Sub-Account token: OAuth access token or Private Integration Token.** Scopes: `clientportal-ai.write`

## Parameters

### Header Parameters

| Name | Type | Required | Description |
|------|------|----------|-------------|
| `Idempotency-Key` | string | No | Makes the request safe to retry: a repeat with the same key returns the first result. |
| `Version` | string | Yes | The API version. |
