# execute inpin function

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).

This can be used to dynamically call functions (for example from the frontend)

- flow `flow`

- function required `inpinfunction`

- flow `flow`

Executes the function whose reference arrives on the inpinfunction pin (an object carrying action_guid), enabling dynamic dispatch e.g. from the frontend. Pin values pass into the function and its return values map back onto this block's outputs; data embedded in the function reference wins over same-named pin values. A missing or non-object reference, an empty action_guid, and a failed call are all SILENT : no error output, the flow just continues.

A typical wiring for [execute inpin function](https://docs.rual.nl/block-types/function%2520execution/function_custom_execute_inpinfunction): a [function trigger](https://docs.rual.nl/block-types/globals/trigger_custom_function) starts the flow; the `flow` out pin feeds [debug](https://docs.rual.nl/block-types/state%2520ui/state_debug).
