Quick start

Integrate your CMS, website, or application with the checkout and licensing API in three steps:

Create an API Key

Go to your store settings and generate a Store API Key for server-to-server authentication.

Create a Checkout Session

POST to the session endpoint with your cart items. You'll get back a signed checkout URL.

Redirect the Customer

Send your customer to the checkout URL. After payment, they're redirected back to your success URL.

Minimal Example (cURL)

curl -X POST https://creativemark.co/api/v1/stores/your-store/checkout/session/ \
  -H "Authorization: Bearer $CREATIVEMARK_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"items": {"YOUR-PRODUCT-SKU": 1}, "currency": "GBP"}'
