Configuration
- Property key — the key to write, with
{assign_key}interpolation (same syntax as Flow Log). Takes precedence over the assign below. - Property key assign — alternatively, name an assign whose raw value is the key.
- Value source — where the stored value comes from. Supports the standard Flow Compose sources (Assign, Extract, Dated property, Literal).
- Value type — the type to store the value as. Set this when the value arrives as text: a date typed as a string stays a string.
- Valid from source — optional date the value becomes true. The literal
"today"resolves to today’s date at run time. Leave empty for a value with no start date. - Id source — optional grouping id, when one key needs parallel histories.
Tips
- A blank key is a no-op with a warning, not a failure — a Flow Each that can’t resolve a key for one item keeps going.
- Values are visible and editable under Organization settings → Data → Organization Properties.
