# 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 --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.laminar.run/building-an-integration/keywords.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
