Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://docs.apica.io/platform-docs/test-data-orchestrator-tdo/user-documentation/workflow-guide/executing-workflow.md). # Executing Workflow Workflow is executed from the main workflow page. When you hover your cursor over a workflow, there are several icons that appear to the right of the workflow name.

Workflow icons

These icons are, from left to right: * Pencil - edit workflow * Page - execution log (shows the workflow activity). This log will append the current run to any prior runs, so if you want a clean log, you should use the next button to clean the log out prior to your run. * Page with slash - empty execution log. This removes all results currently in the log. * Right ('play') arrow - execute the workflow. * Trash can - delete workflow. You will only see this icon if you are an Admin level user. Clicking the 'play' arrow will execute the workflow. While the workflow is running, TDO will slightly gray out and display a 'working' circle. Once done, you can view the execution log.

Workflow execution log with error

Note that if there is an error in your workflow, this will display in the log. The final item in this log is an error telling you that the item you specified is not present. If your message executed without errors the response will look like this.

GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## 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, and the optional `goal` query parameter: ``` GET https://docs.apica.io/platform-docs/test-data-orchestrator-tdo/user-documentation/workflow-guide/executing-workflow.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. 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.
