Getting Started

Set up Genius Checkout in four steps. You'll have a working test integration in about 15 minutes.

1. Create a Merchant Account

1. Visit app.geniuscheckout.com/register
2. Enter your business name, email, and card details
3. After registration, you land on the merchant dashboard

2. Configure a Payment Gateway

1. Go to Gateways in the sidebar
2. Click Configure on PowerTranz Direct or PowerTranz HPP
3. Enter your PowerTranz Merchant ID and Processing Password
4. Select currencies and modes (test/live)
5. Optional settings:

Setting	Description
Capture Mode	sale (immediate) or authorize (hold then capture)
3D Secure	Enable/disable 3DS authentication
Fraud Check	Enable PowerTranz fraud screening
Address Verification (AVS)	Verify billing address with card issuer
Tokenization	Store card tokens for recurring charges

3. Get Your API Key

1. Go to API Keys in the sidebar
2. Click Create API Key
3. Copy the key — it starts with gc_test_ (test) or gc_live_ (live)

TIP

Keep your gc_live_ key out of source control and client-side code. The key is bearer credentials — anyone with it can charge on your behalf.

4. Set Up Webhooks

1. Go to Webhooks in the sidebar
2. Add your endpoint URL (e.g., https://yoursite.com/gc-webhook)
3. Select events: payment.completed, payment.failed, payment.refunded
4. Copy the signing secret
