  title: Salesforce Get Picklist Values for a Record Type
  summary: Resolve an object's record type, then fetch its picklist field values.
  description: >-
    Lightning forms need picklist values that are scoped to a record type. This
    workflow reads the object metadata to discover the record types available on
    the object, then retrieves the picklist values for the requested record type
    so a client can populate dependent and independent picklist fields with the
    correct labels and valid values. Every step spells out its request inline so
    the flow can be read and executed without opening the underlying OpenAPI
    description.
