Find the last confirmed stage of the order
When a Magento order does not reach the ERP or warehouse, start with the last place it is definitely visible. Is the order present in Magento? Has the integration selected it? Has the receiving system acknowledged it? Is it waiting for fulfilment rather than missing entirely?
These are different failure points. The phrase “orders are not syncing” can hide an eligibility rule, a delivery error, a processing backlog or a record that arrived but cannot be released for picking. Trace one affected order through the actual workflow before changing settings.
If the customer appears to have paid but no Magento order can be found, start with the payment-taken-but-no-order guide. That is earlier in the transaction chain than a warehouse export problem.
Map the integration you actually have
Establish whether Magento pushes orders, the receiving system polls for them, or a connector or middleware service sits between the two. Record who operates each component and which system owns the export rules. Do not assume that every connection uses Magento’s message queues.
A practical map needs only a few facts: source order state, selection trigger, delivery method, receiving acknowledgement and the step that marks the order as exported. Include the expected delay. A five-minute scheduled exchange should not be diagnosed using the expectations of an immediate event-driven connection.
Also identify the return journey. Shipment references, stock changes and order statuses may flow back separately. An order can export successfully while the shipment update fails, so use distinct milestones rather than one vague “synced” flag.
Check whether the order should have been selected
Compare one missing order with a similar successful order. Look at the rules agreed for the integration: payment or order status, website, delivery method, product type and any fraud or manual-review condition. The configured rules may intentionally hold an order that is visible in Magento.
Do not change order status merely to force an export. Establish why that status exists and whether a change would trigger fulfilment, customer emails or accounting effects. The right correction may belong in the selection rule, the underlying payment state or the receiving system.
Capture the relevant order references privately and record the observed differences. If a whole group is affected, look for a shared condition such as a newly introduced shipping code or a recent store-view launch. A narrow pattern often gives a more useful starting point than a full-system reset.
Separate delivery from successful processing
A request leaving Magento does not prove the warehouse accepted the order. A connector may report successful transport while the receiving application rejects the data or leaves it in an exception queue. Identify the acknowledgement that actually means the order is ready for the next operational step.
- Not selected: inspect eligibility and the trigger that discovers new orders.
- Selected but not sent: inspect the relevant scheduled job, worker or queue and its latest result.
- Sent but rejected: preserve the response and find the validation condition that failed.
- Accepted but not released: review the receiving system’s stock, customer, address or fulfilment rules.
- Released but not updated in Magento: trace the return acknowledgement or shipment/status integration separately.
Use the same order reference and time zone through the investigation. Different internal identifiers are normal, but the relationship between them should be recorded so that people are not comparing unrelated records.
Look for a data mapping or validation change
Order exports depend on shared meaning, not just a working connection. A shipping code, tax treatment, product SKU, currency or address structure may be valid in one system and unexpected in the other. A newly added value can expose a gap even when previous orders still transfer correctly.
Ask for the receiving system’s actual rejection or exception detail. Then compare the intended mapping with the affected record. Avoid filling missing fields with invented values just to pass validation; that can move the problem into picking, invoicing or delivery.
Changes should be tested with representative examples, including the exception that triggered the incident. Where rules differ by website or market, include those cases explicitly. Our ERP integration and warehouse integration services cover this kind of workflow and mapping work.
Check jobs and queues without losing the backlog
Some integrations rely on scheduled jobs or message consumers; others use external services. Identify the actual processing mechanism first. For Magento-managed asynchronous operations, Adobe documents how consumers retrieve and process queued work.
Inspect the relevant job or consumer’s state, recent failures and backlog trend. A growing queue suggests work is arriving faster than it is being completed, but the reason still needs evidence. A single failed message may need different handling from a stopped worker or a failing external dependency.
Do not clear a queue simply to remove an error count. Those entries may represent unfulfilled customer orders. Establish what each retry will do, how duplicate processing is prevented and how successfully handled records are reconciled.
Reference: Adobe’s message-queue management guidance. Apply it only where the integration uses that mechanism.
Reconcile before replaying orders
Before re-sending a missing batch, check whether any records already arrived under a different identifier or are waiting in the receiving system. A delivery timeout can leave the sender uncertain even though the receiver completed the action.
The recovery plan should identify which orders need replay, who authorises it and how duplicates will be detected. Agree a small controlled sample first where appropriate. Confirm the result at both ends before extending the operation to the full backlog.
Keep a record of recovered orders and any exceptions still outstanding. If staff temporarily enter orders manually, make that visible to the integration owner so an automatic retry does not create a second fulfilment. Recovery is complete when the records reconcile, not merely when the connector stops reporting errors.
What to include when asking for help
Provide the connected systems, direction of the missing update, when it started, expected transfer interval and a small number of affected and successful references through an appropriate private channel. Include recent deployments, new mappings or provider changes.
Do not send passwords, API secrets or unrestricted order exports in an ordinary enquiry. We can agree the minimum secure access and evidence needed. If dispatch is blocked now, explain the operational impact in the emergency support request. Planned reliability improvements belong in a scoped ecommerce integration engagement.
Order synchronisation questions
Does a successful API response mean the order is ready to pick?
Not necessarily. Confirm what that response means in the integration contract and whether the receiving application has accepted and released the order.
Can we just export the whole day again?
First reconcile what already arrived and establish duplicate protection. A bulk replay can create operational problems if the receiving system treats repeated submissions as new orders.
Is every order-sync issue a Magento queue problem?
No. The connection may use polling, a third-party connector or external middleware. Identify the implementation and the last confirmed stage before choosing a recovery action.
