### Answer Unfortunately, I don't have specific documentation about implementing "for loops" for field extraction in Retell AI's Conversation Flow. However, based on the available information, here's the recommended approach: For extracting multiple fields during a conversation, use the Conversation Node → Extract Variable Node pattern rather than trying to loop through extractions. [(1) ]() A community member asked about changing previously captured information and received guidance that using a single Global Extract node can cause issues because "the agent will try to extract data from every sentence, which often causes it to overwrite variables when the user isn't even trying to change them." The recommended pattern is: Conversation Node → Logic Node to avoid loop traps. For more complex field extraction scenarios, you might want to check out: - [Dynamic Variables]() for understanding how to work with variables - [How To Use Retell Conversation Flow (Step-by-Step Tutorial) ]() for visual guidance If you need more specific guidance on iterative field extraction, I'd recommend visiting the [Documentation]() or reaching out to a [certified Retell partner]() .
