# Making your first request

This article guides you through sending your first authenticated v3 API request using one of the following methods.

## Base URL and authentication

| Region | Base URL |
| --- | --- |
| Europe (default) | `https://apihub.document360.io` |
| United States | `https://apihub.us.document360.io` |
| Canada | `https://apihub.ca.document360.io` |

Authenticate every request by sending your API key in the `X-API-Key` header:

```
X-API-Key: YOUR_API_KEY
```

You will use this API key regardless of the tool — in curl as a request header, in Postman as a header on the **Headers** tab, and in the interactive reference through the **Authorize** button.

## Option 1: Using the interactive API reference

The interactive reference provides a browser-based interface to try every endpoint in real time.

1. Open the v3 API reference.
2. Click **Authorize**.
3. Provide your API key and click **Authorize**.
4. Navigate to any endpoint, enter the required values, and click **Execute**.
5. View the response directly in the browser.

## Option 2: Using Postman

Postman lets you import the Document360 v3 API collection and make requests from a graphical interface. This is recommended for testing and team collaboration.

1. Log in to Postman and click **Import**.
2. Choose the **Link** option and paste the v3 OpenAPI URL: `https://apihub.document360.io/swagger/v3/swagger.json`
3. Click **Continue**, then **Import**.
4. Set the base URL, then add a header named `X-API-Key` with your API key on the **Headers** tab.
5. Send a request to any available endpoint.

## Option 3: Using curl

A good first request is to list the projects your API key can access — this also returns the `project_id` you need for most other calls.

```
curl --request GET "https://apihub.document360.io/v3/projects" \
  --header "X-API-Key: YOUR_API_KEY"
```

A successful response returns a paginated list of projects:

```
{
  "success": true,
  "request_id": "req_abc123def456",
  "data": [
    {
      "id": "1c2d3e4f-5a6b-7c8d-9e0f-a1b2c3d4e5f6",
      "name": "Product Docs",
      "description": "Customer-facing product documentation",
      "sub_domain_name": "docs",
      "status": 0,
      "created_at": "2025-01-15T09:00:00Z",
      "modified_at": "2026-06-30T12:00:00Z"
    }
  ],
  "pagination": { "page": 1, "page_size": 25, "total_count": 1, "has_more": false }
}
```

Note

`status` is an integer: `0` = Active, `1` = Inactive. When you authenticate with an API key scoped to a single project, this list returns only that project.

Note

`https://apihub.document360.io` is the default (Europe) host. Depending on where your project is hosted, use `https://apihub.us.document360.io/` (United States) or `https://apihub.ca.document360.io/` (Canada) instead.

Note

On Windows, use double quotes (`"`) instead of single quotes (`'`) in curl commands to avoid errors.
