# Locating your API credentials

## How to find your Client ID and Client Secret to start making authenticated requests.

1. Reloadly uses the [OAuth 2.0](https://auth0.com/docs/protocols/protocol-oauth2) authorization framework. Before your application can call any Reloadly API, it needs to exchange your credentials for an access token. Those credentials — your **Client ID** and **Client Secret** — live inside the Reloadly portal.
   
   **Getting "Full authentication is required to access this resource"?**  
   This error means your request is missing a valid access token, or you're using a token from the wrong environment. Make sure you're generating a token with the correct credentials for the environment you're calling (live vs. sandbox).

   | **Step 1** | **Step 2** | **Step 3** | **Step 4** |
   | --- | --- | --- | --- |
   | Create your account If you don't have one yet, [register for a free Reloadly account](https://www.reloadly.com/registration). No credit card required for sandbox access. | Log in to the portal Go to [reloadly.com/login](https://www.reloadly.com/login) and sign in with your email and password. | Open API settings In the left sidebar, click **Developers**, then select **API Settings**. Your Client ID and Client Secret are displayed on this page. | Switch environments as needed Use the **Live / Sandbox toggle** in the sidebar to switch between environments and view the corresponding set of credentials. |

    
   
   ### **Two environments, two sets of credentials**
   
   Reloadly gives you completely separate credentials for each environment. Tokens generated from one set are not valid in the other.

\*\*Live environment (Production)\*\*

\- Token lifetime: 60 days (5,184,000 seconds)

\- Use for: Real transactions with live customers

\*\*Sandbox environment (Test)\*\*

\- Token lifetime: 24 hours (86,400 seconds)

\- Use for: Development, QA, and integration testing

### **Audience URLs by product**

When you request an access token, you specify an **audience** URL that tells Reloadly which API and environment the token is for. Use the correct URL for your environment.

| Product | Live audience | Sandbox audience |
| --- | --- | --- |
| **Airtime (top-ups)** | `https://topups.reloadly.com` | `https://topups-sandbox.reloadly.com` |
| **Gift cards** | `https://giftcards.reloadly.com` | `https://giftcards-sandbox.reloadly.com` |
| **Utility payments** | `https://utilities.reloadly.com` | `https://utilities-sandbox.reloadly.com` |
