Update lead

PATCH /v1/leads/:id

Updates the fields of an existing lead. Pass only the fields to change. Full list in the field reference, including user fields (ufCrm_*).

Important about email / phone (multifield): On update, Bitrix24 only adds new multifield records. PATCH {"email": "new@y.com"} on a lead that already has an email will not replace the old one — the lead will end up with two emails. This is Bitrix24-specific behavior, not Vibecode. To replace or remove email/phone — edit the lead through the Bitrix24 UI.
