# Authentication

All requests to the DropHub API must be authenticated using an API key. This ensures secure and authorized access to our services.

#### 🔗 Base URL

#### 📥 Authentication Method

DropHub uses **API Key authentication** for all endpoints.

* Pass your API key in the header of each request using the `x-api-key` header.

#### ❌ Missing API Key

If the API key is not included in the request, the API will return a `401 Unauthorized` response with the following message:

**Response**

```json
{

  "Missing API Key"
}
```
