Salesforce AP-219 Exam - Topic 4 Question 14 Discussion

Posted by Lenny on Jun 29, 2026 at 05:37 AM

An admin is working with Order Management licensed as standalone (B2C Commerce is not in the scenario). The admin submits a JSON payload using Workbench and Workbench indicates the operation was successful The second time the same payload is submitted the operation fails. What are two likely causes?

Suggested Answer: B, D

Two likely causes that could make the second submission of the same JSON payload fail are:

The payment data must be updated. The payment data in the JSONpayload contains information such as the payment method, amount, and authorization code. If the same payment data is used for the second order, it may cause a duplicate payment error or an invalid authorization error.

The Order Reference Number must be updated. The Order Reference Number is a unique identifier for each order that is generated by the external system and sent in the JSON payload. If the same Order Reference Number is used for the second order, it may cause a duplicate order error or an invalid order error.

True, but we can't ignore the possibility of needing a new reference number.

But if the first order went through, C seems more likely to me.

I’m leaning towards D. The Order Reference Number should change for each order.

A is definitely not the cause, SKUs don’t change that often.

Wait, how does the Order Reference Number affect it?

I disagree, it could also be B, payment data might need a refresh.
LI
Lilli 3 months ago
C makes sense, stock levels could be the issue.
RE
Reuben 3 months ago
I feel like stock levels are crucial in these scenarios, so C seems like a strong answer, but I wonder if there are other factors at play too.
VI
Viola 4 months ago
I practiced a similar question where payment data was a factor, but I can't recall if it applies here. Could B be relevant?
KI
Kip 4 months ago
I'm not entirely sure, but I think the Order Reference Number might need to be unique for each submission, so D could be a possibility.
CL
Clarence 4 months ago
I remember something about how stock levels can affect order submissions, so maybe option C is a likely cause.
