### Answer I don't have specific information about importing conversation flow versions in the available sources. However, I can share what's documented about working with conversation flow versions: When retrieving a conversation flow, you can specify a version using the version query parameter [(1) ]() . Similarly, when updating a conversation flow, you can target a specific version with the version query parameter, which defaults to the latest version if not specified [(2) ]() . For managing versions in the dashboard, conversation flows support versioning through a publish/draft system. You can use the publish button to publish your agent and create a new draft that you can edit safely. On the phone numbers tab, you can choose which version you want to use [(3) ]() . Could you provide more details about what specific issue you're encountering when trying to import a version? For example: - Are you using the API or the dashboard? - What error message are you seeing? - Are you trying to retrieve, update, or restore a specific version? This will help me provide more targeted guidance.

@AI Evy How do I import a .json

### Answer Based on the available sources, you can import a conversation flow JSON using the "Import Agent" feature in the dashboard [(1) ]() . According to a Discord discussion, when you're in the agent editor, you can use the "Import Agent" option to upload your JSON file . **Important note**: If you encounter an error like "failed to get voice id" when importing, this occurs because the JSON contains a custom voice configuration . You'll need to ensure the voice ID in your JSON matches an available voice in your account, or update it after import. The sources don't provide specific API endpoints for importing JSON directly via code. The documented API methods allow you to create new conversation flows [(2) ]() or update existing ones [(3) ]() , but these require you to structure the data programmatically rather than uploading a raw JSON file. If you're still having trouble with the import process in the dashboard, could you share what specific error message you're seeing? This will help identify whether it's the voice ID issue or something else.
