It has its own address suffix and is stable for a given account, but it is not a phone number and cannot be dialled or messaged as one.","WhatsApp spent years exposing every group member's phone number to every other member. The linked identity replaces that: in newer clients a participant in a group or a commenter on a channel can be represented by a LID instead, so the number stays private unless the two people already have each other saved. For anyone automating WhatsApp this is the single biggest change of the last two years, because code that assumed a sender is always a phone number now sees an identifier it cannot match against a CRM. Wapito resolves the mapping wherever it can: it reads the sender-alternate field the engine provides, falls back to a cached mapping table, then to a direct lookup endpoint, and only if all three fail does it hand you an event whose sender number is null with the LID alongside. Treat the LID as the durable key and the phone number as an enrichment that may be missing. Storing both, and keying your own records on the LID, is what stops a group-automation system from breaking as more of the network migrates.",{"example":7,"field":8},"{\"from\": null, \"from_lid\": \"185234567890123@lid\", \"participant\": \"185234567890123@lid\"}","from_lid","The Cloud API does not expose LIDs at all.
