# Glossary

***

#### **Workflow**

A programmatic sequence of steps triggered by an event and executed automatically by Wundaflow. Workflows can be paused, resumed, cancelled, and queried via API.

***

#### **Task**

An individual operation within a workflow. Tasks can be native JavaScript functions, external API calls, or serverless function invocations.

***

#### **Trigger**

A condition or event that starts a workflow execution. Triggers can be based on blockchain events, schedules, API calls, or other third-party system events.

***

#### **Signal**

A message sent into a running workflow to update its state or resume execution from a paused state.

***

#### **Worker**

An external component that polls for and executes tasks defined in a workflow. Can be used to integrate custom logic or handle domain-specific operations.

***

#### **Webhook**

A real-time HTTP POST message sent to your application to inform it of events in a workflow lifecycle or other system-level events.

***

#### **Retry Policy**

A configuration attached to tasks or workflows that defines how failed steps should be retried, including back-off strategy and limits.

***

#### **KV Store**

A key-value store either (1) scoped to a single workflow execution, used to persist lightweight data between tasks; or (2) scoped to global context, used to persist long-term data across all workflows.

***

#### **Wallet**

A blockchain wallet that can be generated, managed, and used to sign transactions as part of a workflow. Wundaflow can generate wallet addresses programmatically.

***

#### **Connector**

A prebuilt integration with a third-party platform (such as AWS, OpenAI or Replicate). Enables Wundaflow to execute functions using customer-provided credentials without needing to host infrastructure.

***

#### **Execution**

A specific instance of a workflow being run with defined inputs. Executions have a lifecycle and can be monitored or controlled via API.
