# Template versioning

> Manage template versions — draft, active, and inactive — with safe iteration and rollback.

Template versioning lets you iterate on designs without breaking production, track changes, and roll back when needed.

## Prerequisites

* A template you want to version

## Version states

| State        | Description                              | Usage                   |
| ------------ | ---------------------------------------- | ----------------------- |
| **Draft**    | Work in progress, not used in production | Development and testing |
| **Active**   | Current production version               | Live message sending    |
| **Inactive** | Previous versions, archived              | History and rollback    |

New templates start as **Draft**. When ready, activate a version; it becomes **Active** and the previous active version becomes **Inactive**.

## Creating versions

### New version from current

1. Make changes to your template in the builder
2. Click **Save as New Version**
3. A new version is created in **Draft** state
4. The current **Active** version stays live until you activate the new one

### From version history

1. Open the template and go to **Version History**
2. Click **Create New Version**
3. A new draft is created from the current active version

Versions are auto-numbered sequentially (1, 2, 3, …). Numbers are never reused.

## Managing versions

### View version history

1. Open the template
2. Click **Version History**
3. See all versions with number, state, and timestamp

### Activate a version

1. In Version History, select a **Draft** version
2. Click **Activate**
3. That version becomes **Active**; the previous active becomes **Inactive**

Only one version can be Active at a time. Activating a draft does not automatically deploy; use your normal process to send messages with the new content.

### Roll back

To roll back: open Version History, select the **Inactive** version you want to restore, and **Activate** it. It becomes Active again; the current Active becomes Inactive.

## Best practices

* Use drafts for all experimental changes
* Activate only after testing (e.g. send to a test channel)
* Use version history to compare and audit changes
