Question 50/96
Universal Containers (UC) processes orders in Salesforce in a custom object, Order__c. They also allow sales reps to upload CSV files with thousands of orders at a time.
A developer is tasked with integrating orders placed in Salesforce with UC's enterprise resource planning (ERP) system.
After the status for an Order__c is first set to 'Placed', the order information must be sent to a REST endpoint in the ERP system that can process one order at a time.
What should the developer implement to accomplish this?

What should the developer implement to accomplish this?
Correct Answer: A
* Why Queueable Class?
* Queueable Apex supports callouts and allows chaining to process one record at a time efficiently.
* The trigger detects when theOrder__cstatus changes to "Placed" and enqueues the Queueable class to perform the callout.
* Why Not Other Options?
* B. Batchable class: Batch jobs are ideal for bulk processing but not suited for single REST callouts.
* C. Flow with invocable method: Flows are less efficient and limited in handling callouts for large- scale operations.
* D. @future method: While it supports asynchronous callouts, it does not allow chaining, making Queueable more suitable.
