# Publishing to Live

> Learn how to publish your Flow Designer agent and understand what happens when you deploy changes to production.

![](https://storage.googleapis.com/granular-changelog/doc-images/flow_designer_publish.png)

Before publishing your Flow Designer agent, you need to resolve all issues in the **issue checklist**. Once published, your Flow Designer configuration will replace the existing production version of your agent.

## Before Publishing

### Resolve Issues in the Issue Checklist

Before you can publish, review and resolve all items in the issue checklist:

* **Missing required nodes:** Ensure all required nodes are configured
* **Invalid connections:** Fix any broken or invalid node connections
* **Missing variables:** Ensure all referenced variables are collected or defined
* **Configuration errors:** Resolve any configuration issues in your nodes

The issue checklist helps ensure your Flow Designer agent is ready for production and will work correctly when deployed.

## Publishing Your Agent

Once all issues are resolved:

1. Click the **Publish** button in the Flow Designer
2. Confirm the publication
3. Your Flow Designer configuration is deployed to production

**Important:** Publishing immediately replaces the existing production version of your Flow Designer agent. All active calls will continue using the previous version, but new calls will use the newly published version.

## FAQ

#### What happens to active calls when I publish?

Active calls continue using the version that was live when they started. Only new calls will use the newly published version.

#### Can I unpublish changes?

You can publish a previous version to revert changes.

#### Do I need to publish sub-agents separately?

No. When you publish your main Flow Designer agent, all sub-agents are published together as part of the same configuration.

#### What if I publish with unresolved issues?

You cannot publish if there are unresolved issues in the issue checklist. Resolve all issues before publishing to ensure your agent works correctly in production.

## Next Steps

* [Test your agent with Simulations](/simulations) to verify it works correctly before real calls
* [Deploy your agent](/deploy-your-agent) to make it available via telephony, WhatsApp, or websocket
* [Review Flow Designer Basics](/flow-designer) if you need to make changes to your flow
