Standard Module

Core BPMN tasks shipped with every engine: I/O, routing, HTTP, delay, log, and variable handling.

Workflow Engine V 1.0.0

Description

What this does

The Standard Module is the foundational module included with every Workflow Engine instance. It provides the essential building blocks for every workflow — handling user I/O, routing decisions, calling external APIs, and managing variables.

It registers both channel-specific I/O tasks (StartTask, EndTask, InputTask, OutputTask for the Chat channel) and channel-agnostic generic tasks that work everywhere. Other modules (Twilio, Aculab, ACS) plug their own channel handlers into the same shared task shapes.

What you can build

  • Conversational chat flows using InputTask and OutputTask paired together
  • Branching logic with SwitchTask against context variables
  • Outbound API integrations via HttpTask with built-in SSRF protection
  • Variable composition and cleanup with SetVariableTask (Set/Delete modes)
  • Localized flows with LanguageTask, normalized text with StringNormalizationTask, scheduled pauses with DelayTask, audit checkpoints with LogTask, and controlled failure paths with ThrowErrorTask

See the setup guide for configuration and full task reference.
