Scope

Any

Update (palette name Update) changes named variables that already exist. It writes on the nearest owner of that name (this body, or an outer loop/workflow scope). It does not create a new name. If a key is missing, the block fails with Variable not found.

Use Set (or the Variables list on Start / Lambda) to create the name first.

Each row is a Key plus a Value (fixed or a context path). The same object is written to the data pipe.

Configure

Setting	Description
Key	Existing name other blocks already use (for example `customerId`). Same naming rules as Set.
Value	Literal or a variable path from this block’s context
Add variable	Appends the row

Add as many rows as you need. Duplicate keys are ignored.

Handles

Handle	Role
In (target)	Incoming connection
Out (source)	Continues after the names are updated

Pipe schema

The next block reads this on the data pipe (pipe.value).

Field	Type	Description
Updated variables	object	One property per Key, with that row’s resolved value

Downstream blocks can also bind the names directly.

Use case

After creating total on the main path, update it inside a loop so the main path still sees the new total.
Set flags that later conditions on the main graph should see.
