The first step to use the plugin properly is to select those carriers usually entitled to be in charge of the shipping of your orders. To do it, go to YITH -> Order Tracking -> Carriers.
If the carrier you are looking for is not included in the list, submit a ticket in our support platform, specifying the carrier’s name and URL and a valid tracking code (even if expired). We will release an update with the new carrier on the list as soon as we can.
However, in case you want to add manually the new carrier, you can open the class.carriers.php file that you find in the plugin and add a new element. Don’t forget that the release of a new update could cause the loss of your changes. For this reason, we suggest you contact our support if you want to add a new carrier.
To set up a carrier among the ones selected, go to the plugin settings dashboard and select it in the “Default carrier name” field.
