# How to Make an API Call (Postman)
export const WhatComesNext = ({children, href}) =>
;
This how-to covers making an API call using OAuth 2.0 and **Postman**. For the full non-Postman setup, where you manage the entire token lifecycle, see the [OAuth 2.0 Setup Workflow Guide](/docs/current/guides/oauth-workflow-guide) instead.
## Prerequisites
Before you begin:
* You have [configured Postman](/docs/current/how-tos/oauth-postman/how-to-configure-postman-for-oauth) for OAuth 2.0
## Steps
### 1. Create an HTTP Request
In the Postman collection where you've configured OAuth 2.0:
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`
Each API endpoint has both a **Staging** and a **Production** URL. You can find these in the [Pleo API Reference](https://developers.pleo.io/reference/employees/search-for-employees) sections.
### 2. Add authorisation
1. Click the **Authorization** tab
2. Select **OAuth 2.0** as the **Auth Type**
3. Select the OAuth 2.0 token you previously created from the **Token** dropdown menu
4. Postman automatically injects: `Authorization: Bearer `
### 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
## Result
After completing these steps:
* You have successfully made a Pleo API call using OAuth 2.0 in Postman
