Retino Returns continuously monitors and updates the status of all tracked shipments. This article explains how the synchronization works and what factors influence its frequency.
Synchronization Intervals
The system synchronizes shipments in the following intervals:
The first synchronization occurs immediately after adding the shipment to the system
Standard synchronization takes place every 60 minutes ± 20% (48-72 minutes) with a random offset to distribute the load
If a synchronization error occurs, the next attempt will be made the following day
Shipment synchronization stops after 120 days from creation or upon reaching a final status (e.g., delivered)
Special Intervals for Selected Carriers
Some carriers have different synchronization intervals:
DHL - synchronization every 24 hours ± 20%
Austrian Post - synchronization every 4 hours ± 20%
The random ± 20% offset helps distribute the load evenly across servers and ensures stable system operation.
Troubleshooting Synchronization Issues
Several types of problems can occur during synchronization:
Carrier Not Detected
The system was unable to recognize the carrier based on the shipment number or tracking URL. In this case, please wait for the next synchronization or verify the accuracy of the entered data.
Missing Credentials
Credentials are required for tracking shipments from some carriers. If missing, the system will notify you and prompt you to provide them.
Invalid Credentials
If the entered credentials are invalid, synchronization will pause, and you will be prompted to update them.
Shipment Not Found
The carrier does not have the shipment in their system. This could be due to:
The shipment has not yet been registered in the carrier's system
An error occurred during carrier detection
Technical Issues
In case of technical problems (carrier API outage, connection issues, etc.), the system will automatically retry synchronization the following day.
When Shipment Synchronization Stops
Shipment synchronization ends in the following cases:
The shipment reaches a final status (delivered, returned to sender, cancelled)
120 days have passed since the shipment was created
The carrier cannot be detected, and the shipment cannot be tracked
Required credentials are missing and have not been provided
Shipment Timestamps
The system tracks several important timestamps for each shipment:
Order time - when the shipment was ordered
Pickup time - when the carrier picked up the shipment for delivery
Delivery time - when the shipment was delivered to the recipient or drop-off location
Collection time - when the recipient picked up the shipment from the drop-off location
The system also calculates the number of weekend days between ordering and delivery, and between pickup and delivery, for delivery time analysis purposes.
