Does API allow to track more than one container at once?
Yes, it allows, however, in order to track more than one container at once you need to open at least a trial account. That is why you couldn't able to do it from the tracking tool on the ShipsGo home page. You can track more than one container at once with API if you have the master bl number. However, if you have more than one container which is carried by the same shipping line but not belongs the same BL you need to enter the container numbers respectively and submit the form after entering the shipping line and other required data.
Besides, if you have a big amount of containers to track, then you can use an excel upload option to track more than one container at once. The steps for uploading excel as follows;
1. Download excel sample
2. Fill the sample by sticking the sample structure
3. Upload prepared excel file by using the "Browse" button
You can reach the "Excel Upload List" option from the "Track New Shipment" section at the left sidebar of your dashboard.
Last but not least, API code also allows you doing the above steps automatically by integrating our API PHP or HTML code to your system. See full details in here
