# listDealCustomFields

List a deal pipeline's custom-field DEFINITIONS (by pipelineId from listPipelines): id, name, type (TEXT/NUMBER/DOLLAR/DATE/LINK/DROPDOWN), dropdown options, allowMultiple, defaultValue. Deal custom fields are per-pipeline. DEFINITIONS ONLY: no deal's recorded value appears here: read those from getDeal's `customFieldValues`, which lists only the fields a given deal has been given a value for. Use each id as the customFieldId in the deal's customFieldValues input on createDeal / updateDeal to write values.
