# decrement server state

This block is part of the [`state ui`](https://docs.rual.nl/block-types/state%20ui) group and was last modified in core [`v10.4.28`](https://docs.rual.nl/core-versions/100428).

Sends a state update to the frontend and triggers updates based of it.

- flow `flow`

- state key required `value` State key to update

- number required `number` Number to decrement with

- skip trigger `condition` if `true` given, it will not send this update back to the backend.

- flow `flow`

A typical wiring for [decrement server state](https://docs.rual.nl/block-types/state%20ui/state_decrement_state): a [function trigger](https://docs.rual.nl/block-types/globals/trigger_custom_function) starts the flow; [value](https://docs.rual.nl/block-types/value/value_default) feeds the `key` pin; [number](https://docs.rual.nl/block-types/number/number_default) feeds the `number` pin; the `flow` out pin feeds [debug](https://docs.rual.nl/block-types/state%20ui/state_debug).
