Storage: Update step

step_type: storage_update

Updates an existing item in a Storage by id. Only the fields you provide are changed — everything else on the item is left as-is.

Configuration

Field	Type	Required	Description
storage	string	required	The Storage the item belongs to, identified by its machine name.
item_id	string	required	The id of the item to update — e.g. from a previous Storage: Write or Storage: Read step.
values	object	required	The fields to change, merged into the existing item. Any fields left out keep their current value. Fields and types match the selected Storage's schema.

Output

The step's output includes the updated item's id and its full data after the merge.

When to use it

• Updating a status or counter field on a record created earlier in a workflow (or a previous run).
• Applying a partial change — e.g. bumping a stock count — without needing to resend the whole item.

Note

This is a partial merge, not a full replace — you don't need to repeat unchanged fields in values. Values are expression-aware, same as Storage: Write.
