A typical wiring for [verify](https://docs.rual.nl/block-types/json%20web%20token/function_jwt_verify): 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 `token` pin; [value](https://docs.rual.nl/block-types/value/value_default) feeds the `secret` pin; the `flow` out pin feeds [debug](https://docs.rual.nl/block-types/state%20ui/state_debug).
