# Test Mode

> Test your store without processing real payments.

Test mode lets you test the complete shopping experience — including checkout and payment — without processing real charges. When enabled, all payment gateways automatically switch to their test/sandbox credentials.

## How It Works

Navigate to **Settings > Developer Settings** to access the test mode toggle.

When test mode is **on**:

* All payment gateways use their test API keys
* Orders are processed normally but payments go through sandbox environments
* You can test the full checkout flow with test card numbers
* All other store functionality (inventory, emails, fulfilment) works as normal

When test mode is **off**:

* All payment gateways automatically switch back to their live API keys
* All integrations are set to live mode
* Real payments are processed

<Warning>
  Always turn off test mode before making your store available to real customers. Orders placed in test mode use sandbox payment processing.
</Warning>

## Setting Up Test Credentials

Each payment gateway has separate fields for live and test credentials:

### Stripe

Enter your Stripe test publishable key and test secret key. You can find these in your [Stripe Dashboard](https://dashboard.stripe.com/test/apikeys) under Developers > API keys (make sure "Test mode" is toggled on in Stripe).

### PayPal

Enter your PayPal sandbox client ID and secret from the [PayPal Developer Dashboard](https://developer.paypal.com/dashboard/applications/sandbox).

### PayFast

Enter your PayFast sandbox merchant ID, merchant key, and passphrase from the [PayFast Sandbox](https://sandbox.payfast.co.za).

## Test Card Numbers

When using Stripe in test mode, you can use these test card numbers:

| Card            | Number                |
| --------------- | --------------------- |
| Visa (success)  | `4242 4242 4242 4242` |
| Visa (declined) | `4000 0000 0000 0002` |
| 3D Secure       | `4000 0027 6000 3184` |

Use any future expiry date and any 3-digit CVC.
