# Keywords

## Invoking the system

Laminar Keywords were built to allow for complex use cases to be handled within workflows.

Each flow within a workflow can invoke a keyword by transforming its data to a format that is represents a keyword and what data it expects.

## Use cases

Keywords can be used to:

1. Iterate over data and run a workflow with each element
2. Conditionally invoke workflows
3. Adjust flow destination request metadata (headers, query params, body) dynamically
4. Exit workflows early
5. Resolve requests from external APIs that invoked Laminar and asynchronously continue running workflows
