Description, as the server wrote it WRITE (uses quota): look up ONE tracking number directly at the carrier right now, without registering it. Costs 1 quota per call (standard: carrier data up to 3 hours old). If the number is already registered, a changed result is also pushed to the account. Not supported for USPS, Royal Mail, Australia Post, Direct Freight Express, DHL eCommerce US and DHL Global Forwarding; some accounts are not enabled for real-time lookups. POST /getRealTimeTrackInfo.
