}Status Notes
- Thailand only: this adapter uses the Thai site's tracking API. Flash Express Malaysia and the Philippines are not covered because their sites block automated requests.
- Times: scan times are Thailand time (
Asia/Bangkok), so bothtimestampandlocalTimeare set. - Signer: the recipient's name and proof-of-delivery photo are shown by Flash Express only to logged-in users, so
signedByis filled only when the API returns it.
