Magento 2配置Payment Express Checkout：PxPay/PxPost字段填写咨询

Hey there, let’s walk through each of these Payment Express (now part of DPS) configuration fields for your Magento 2 store—all of these values are tied directly to your DPS merchant account, so you’ll need to pull them from your DPS dashboard or reach out to their support team if you can’t locate them:

• PxPay UserId: This is your unique merchant ID for the PxPay service, provided by DPS when you sign up. Think of it as the "username" that identifies your store to DPS’s PxPay API. You’ll find this in your DPS merchant portal under the PxPay settings section.
• PxPay Key: A sensitive secret string that pairs with your PxPay UserId to authenticate API requests between Magento and DPS. Copy this exactly (no extra spaces or typos!)—it’s case-sensitive and should be kept secure. You’ll retrieve this right alongside your UserId in the DPS portal.
• PxPay Url: The API endpoint where Magento sends PxPay payment requests.
  • Live environment: https://sec.paymentexpress.com/pxpay/pxpay.aspx
  • Sandbox/testing: https://uat.paymentexpress.com/pxpay/pxpay.aspx
    Double-check with DPS if you’re using a custom setup, as these endpoints rarely change but it’s good to confirm.
• PxPost Username: This is the dedicated username for the PxPost service, which handles transaction management tasks like refunds, status updates, and post-payment verification. You’ll get this from DPS when you enable PxPost for your merchant account, located in the PxPost section of your dashboard.
• PxPost Password: The secure password paired with your PxPost Username to authenticate PxPost API calls. Treat this like any other sensitive credential—don’t share it publicly, and ensure you input it correctly (it’s case-sensitive!).
• PxPost Url: The endpoint for PxPost API requests.
  • Live environment: https://sec.paymentexpress.com/pxpost/pxpost.aspx
  • Sandbox/testing: https://uat.paymentexpress.com/pxpost/pxpost.aspx

Quick Tips: #

• If you’re testing, make sure you use DPS’s sandbox account credentials and the UAT URLs—don’t use live details in a test environment!
• After saving your configuration, run a small test transaction to confirm everything is working as expected.
• If you can’t find any of these values in your DPS dashboard, reach out directly to DPS support—they’ll help you locate or reset them.
