MB-920 Practice Question: The Dynamics 365 Commerce administrator for a…
You are the Dynamics 365 Commerce administrator for a medium-sized retail company that operates 20 physical stores and an online store. The company uses Dynamics 365 Commerce with the built-in payment connector for credit card processing. Recently, the company started experiencing a high number of abandoned carts in the online store. Customers report that when they attempt to pay using a credit card, they receive an error message stating 'Payment authorization failed.' However, the same credit cards work fine when used in physical stores. The IT team has verified that the payment connector is configured correctly and that the payment gateway is operational. The online store's checkout page loads correctly and customers can enter their payment details. The error occurs only during the authorization step. What should you do to resolve this issue?
⚠ Common exam trap
It's easy for candidates to assume a global payment method reconfiguration in HQ (Option C) will fix a channel-specific issue, or they may incorrectly think a hardware station (Option A) is needed for online payments, when in fact the online store requires a properly configured payment connector for its channel.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Review and update the payment connector configuration for the online store channel.
The issue is isolated to the online store channel, where the payment connector configuration may be missing or incorrect for that specific channel. Since the physical stores process payments successfully, the problem is not with the payment gateway or the connector itself, but with how the connector is configured for the online channel. Reviewing and updating the payment connector configuration for the online store channel ensures that the authorization request is properly formatted and routed.
