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.

API Access Values — Key ID & HMAC Key

The other two values live in the API Access area for the gateway.

  • Key ID: Clearly stated in the API Access section.
  • HMAC Key: Generated on the API Access page.
