Hi,
The MaltaPost integration is not working correctly. In the case of MaltaPost there is a GET API that you can use to retreive Tracking Details.
Example:
curl 'https://www.maltapost.com/TrackAndTraceApi/v1/trackedItems?barcode=RC588472451DE' -H 'accept: application/json'
Response:
{"foreignCode":"RC588472451DE","movements":[{"description":"Item created","location":"82066003","date":"2020-04-29T17:21:00"}]}
I am willing to attempt and fix this myself, if this is an open source project or you're willing to accept some help
