I want to add using the /rest/V1/shipment/track
API. My shipment. We work with 3 shippers:
DHL
UPS
PostNL.
Now I need to know the carrier_code
in order to add the correct information for the tracking link to work. However, I’ve googled for a long time and found no such thing as a list of exact codes need to send for each service. Nor does it say in my shop backend.
Is the title
field under shipment free to fill in yourself?
