# execute in queue

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

## Function Selection Required

This block requires you to choose a custom function to execute when triggered. You must manually select the function you want to use using the function selector modal. To access the modal, click the white button on the block.

Executes the given function on a given time using the queue and doesn't wait for it to be executed.

- flow `flow`

- unique ID `value` A unique ID will make sure it doesn't make a new one if a queue item already exists with this ID.

- Execute at `date` The time this function should run (rounded to the nearest 10 sec).

Default `now`

- Debounce `condition` This allows for a `debounce` (remove old, create new one) effect on this function, requires a `unique id` to work.

Default `false`

- flow `flow`

- queue `object` The queue document

Fire-and-forget in production: enqueues the selected function to run in the background at the timestamp pin (defaults to now) and continues immediately : the Go executor never populates the queue_doc output. In simulation, debug, or staging it runs the function INLINE and waits, mapping return values back like custom execute. A unique_id deduplicates pending queue items (stored as "bp:{unique_id}"); debounce=true replaces the pending item with the same unique id instead of skipping.
