What this service solves
Give fulfillment staff a single queue for a defined set of order exceptions. The workflow reads order events, classifies them using the agreed rules, and creates a task linked to the source event. Staff can see what needs attention, who owns the next step, and which failures can be retried.
What you get
Routed exception queue
Each matched exception produces an owner task with the order reference, rule, and source event.
Retry and ownership path
The fulfillment owner can identify an incomplete handoff and check the source record before attempting a repeat.
What’s included
Read order events
Read order events using the approved access and identify the record and event attributes needed by each rule.
Classify agreed exceptions
Apply up to three agreed rules, with a defined result for an incomplete event or an event that arrives out of order.
Create an owner task and trace its source event
Create a task for the designated queue owner and preserve the source event reference. Agree how staff should inspect or retry a failed handoff.
How implementation works
Select exception rules
Choose the exceptions that belong in the queue and agree which event and conditions prove each one occurred.
Connect and deduplicate
Connect the storefront and operations queue. Use stable event or order identifiers to distinguish a repeat from a new exception.
Test delayed and repeated events
Test delayed and repeated events and trace the resulting task or exception back to its source.
Technical considerations
- Event identity and ordering
- Use the event or order references available from the storefront and agree how to distinguish a new exception from a repeat. Compare the source event time or current state where supported. If the source cannot resolve the order of events reliably, name the reconciliation step the owner will use.
- Queue handoff
- Carry the rule, order reference, and source event into the task so the owner can verify what triggered it. Keep the storefront access read-only. Define which failed handoff can be retried and where the owner should check for an existing task first.
Systems, inputs & prerequisites
Order events, exception examples, a fulfillment owner, and expected volumes.
- Representative order events, examples for each exception rule, and an estimate of expected event volumes.
- Read access to the storefront data and a fulfillment owner who can confirm how tasks are resolved or retried.
Starting scope & pricing
Base scope
One storefront, one operations queue, up to three rules, and read-only order access.
Illustrative workflow
Read the event
Check the order ID, event timestamp, and status against the rule.
Route the exception
Create the task with the source event and the designated fulfillment owner.
Recheck the source
Compare late or repeated events against the existing task before opening another.
Validation & handover
- Replay an event for each agreed exception rule and verify the correct task owner and trace back to the source.
- Exercise a repeated event and confirm that the queue reflects the agreed duplicate handling.
- Test a late event and verify the result against the selected reconciliation rule before handoff.
- Show the queue owner how to inspect a failed handoff and determine whether a repeat is appropriate.
Limitations & possible extras
Limitations
Storefront access is read-only. Downstream writes, higher event volumes, and API upgrades are separately scoped. Missing stable identifiers or delayed events can require additional reconciliation.
Delayed events and unreliable identifiers need explicit reconciliation.
Possible extras
Storefront API upgrades, high-volume processing, or downstream write actions.
Questions about this service
Will the workflow change orders or issue refunds?
The starting scope reads order events and creates tasks for the operations queue. Staff make order changes or refunds through their existing authorized process.
What if the same order has a new exception after its first task is closed?
Agree on how to distinguish a new occurrence from a repeat delivery. The decision depends on the rule and which event or state identifiers the storefront exposes.
What if a delayed event refers to a status that is no longer current?
Use the agreed comparison of event time and current state where available. If the evidence is incomplete, the owner can reconcile the task with the source before acting.
Can we use the same queue for another storefront?
The starting scope covers one storefront. A second source needs a review of its event access, identity, and how its records will be distinguished in the queue.
