A typical wiring for [open connection](https://docs.rual.nl/block-types/apn/function_apn_open_connection): 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; [value](https://docs.rual.nl/block-types/value/value_default) feeds the `keyid` pin; [value](https://docs.rual.nl/block-types/value/value_default) feeds the `teamid` pin; the `flow` out pin feeds [debug](https://docs.rual.nl/block-types/state%20ui/state_debug).
