# Generate Access Token

> Use client credentials to obtain a JWT for Account and Liquidity APIs.

## Overview

This is the first step for any API call. Use your `apiClientId` and `apiClientSecret` (Basic auth) to get a short-lived `accessToken`. That token is then sent as `Authorization: Bearer ...` to other endpoints.

## Prerequisites

* `apiClientId` and `apiClientSecret`
* Base URL: `{{ACCOUNT_URL}}` (staging or production)

## Request

```bash theme={null}
curl -X POST "{{ACCOUNT_URL}}/v1/ext/jwt/generate-token" \
  -u "$API_CLIENT_ID:$API_CLIENT_SECRET" \
  -H "Content-Type: application/json" \
  -d '{}'
```

## Response (200)

```json theme={null}
{
  "accessToken": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9..."
}
```

## Usage Tips

* Store `accessToken` securely and reuse until it expires.
* Do not expose client credentials in client-side code.
* Rotate credentials periodically.
