Connecting to the 2Checkout API
To connect to the API, you need your merchant code, secret key, and secret word. These unique codes are automatically generated for your account, and you can retrieve them from your Control Panel Dashboard → Integrations → Webhooks and API. Copy the merchant code (found in the API section) and the Instant Notification Service (INS) secret word found in the Secret word area.
