This how-to covers making an API call using Standalone API Keys and **Postman**. For the full cURL instructions, where you use the command line, see the [How to Make an API Call Using a Standalone API Key](/docs/current/how-tos/api-keys/how-to-make-an-api-call-using-standalone-api-keys) instead.

## Prerequisites

Before you begin:

* You have [generated a Standalone API Key](/docs/current/how-tos/api-keys/how-to-generate-standalone-api-keys)

## Steps

### 1. Create an HTTP Request

In your Postman collection:

1. Click **New** and then select **HTTP Request**
2. Ensure that the HTTP method corresponds to the endpoint being called, for example: `GET`
3. Enter the **Staging URL** for the Pleo API you want to test, for example: `https://external.staging.pleo.io/v2/employees`

</div>

### 2. Add Authorisation

1. Click the **Authorization** tab
2. Select **Basic Auth** as the **Auth Type**
3. Enter your **Standalone API Key** as the **Username**
4. Leave the **Password** field blank

</div>

### 3. Send the Request

1. Click the **Send** button at the top of the screen
2. If everything is configured correctly, you should receive a JSON response

<div style={{ textAlign: "center" }}>
  <img src="https://mintcdn.com/pleo-61d4d38b/_rkxCoO48Dr_L3ku/images/current/standalone-api-keys/standalone-api-keys-postman-response.png?fit=max&auto=format&n=_rkxCoO48Dr_L3ku&q=85&s=93bd7e8e59acc753893d1fb449bccef1" alt="Postman GET HTTP Response" width="100%" style={{ display: "block", margin: "0 auto" }} data-path="images/current/standalone-api-keys/standalone-api-keys-postman-response.png" />
</div>

## Result

After completing these steps:

* You have successfully made a Pleo API call using Standalone API Keys in Postman
