# Utils, Logic, and Others This section covers utility nodes for data processing, logic nodes for controlling workflow flow, and bonus features for advanced use cases. Use these nodes to add branching, loops, code execution, and other programmatic control to your workflows. ### In this section

Topic	Page
Utils Helper nodes for common data tasks — custom API calls, shared memory, delays, and more.	/spaces/FSlso1Kjob5CLDrh0dVn/pages/Zof3etLdRGP6MmrBNvi8
Logic Control flow nodes — conditionals, loops, routing, and code execution.	/spaces/FSlso1Kjob5CLDrh0dVn/pages/jTibWaU8CBxAS1LD4AsN
Bonus Features Additional workflow tools including sharing, skipping, and replacing nodes.	/spaces/FSlso1Kjob5CLDrh0dVn/pages/YgEf5lz1TntnvwDC7GW4

### Start with what your workflow needs * Need to branch based on a condition? Start with [**If/Else Node**](/workflow-builder/utils-logic-and-others/logic/if-else-node.md). * Need to run custom code? Use [**Code Node**](/workflow-builder/utils-logic-and-others/logic/code-node.md)**.** * Need to call an external API? Use [**Custom API**](/workflow-builder/utils-logic-and-others/utils/custom-api.md). * Need to iterate over a list? Use [**Loop Subflow**](/workflow-builder/utils-logic-and-others/logic/loop-subflow.md). --- # 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.stackai.com/workflow-builder/utils-logic-and-others.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.
