First Data Payment Settings
Connect your First Data account to WP EasyCart and start sending payment requests through your gateway. It all comes down to four values — two from your Terminal, two from API Access. Find them. Enter them. Done.
Terminal Values — Gateway ID & Password
The first two values are related to the Terminal in your First Data account.
- Gateway ID: Clearly printed along with the terminal in your account.
- Gateway Password: Must be set in the details for the gateway.

- HMAC Key: Generated on the API Access page.
