I ordered a battery for my Samsung S7 on AliExpress and it was shipped via Maldives Post. The tracking number is GXA102019478. The Maldives post website loads the tracking on the main page via a POST request to
http://www.maldivespost.com/api/tracking. The request includes two parameters: tracking_number (self-explanatory) and request_number (which seems to be the XSRF-TOKEN delivered as a cookie when the main webpage is loaded). Beware, looking up a tracking number too many times seems to return an empty response.
