Resolve Names

Batch-resolve record IDs to display names.

Accepts up to 50 items. Groups by object type and fetches each group in a single SQL query (WHERE id = ANY($1)), so a form with 10 lookup fields across 3 object types costs only 3 DB queries instead of 10.

Each item may set display_field to override the default name waterfall — useful when the lookup label should show e.g. account_number instead of name. Response keys are <ObjectType>:<id>:<display_field or "">.
