# API Authorization

> Learn how to authenticate your API requests using your Account ID and API secret key.

## API Authorization Guide

To interact with the NLPearl.AI API, you need to authenticate your requests by including your Account ID and API secret key in the request header. This ensures that your API calls are secure and correctly attributed to your account.

### Authorization Header Format

Include the following authorization header in all your API requests:

```http theme={null}
Authorization: Bearer AccountId:SecretKey
```

The ***Token*** must be in the form `AccountId:SecretKey`.

**For example**:

```http theme={null}
Authorization: Bearer 66552698d60e456235eae520:tWPqr5EEZv2dxqutv58NsCg7NuqGc1tX
```

You can retrieve your Account ID and Secret Key in [our platform](https://platform.nlpearl.ai/app/settings/api).

### Example API Request

Here’s an example of how to set up the Authorization header for an API request using cURL:

```bash theme={null}
curl -X GET "https://api.nlpearl.ai/v2/endpoint" \
     -H "Authorization: Bearer 66552698d60e456235eae520:tWPqr5EEZv2dxqutv58NsCg7NuqGc1tX"
```

Replace `66552698d60e456235eae520` and `tWPqr5EEZv2dxqutv58NsCg7NuqGc1tX` with your actual Account ID and API secret key.
