Layout version history

Every time a layout is saved, the app keeps a version: the layout and all its languages as they were at that moment. The app keeps the newest 25 versions of each layout. Connect GitHub and every version is also kept in your repository, so history is unlimited, and editing a layout's file in the repository updates the layout in the app. See Keep unlimited layout history on GitHub.

Versions are created when you save in the editor, save a translation, change the layout through the API or an AI assistant, or restore a version.

View and restore

1. Open the layout and click Version history.
2. Click View on a version to see its subject and a preview.
3. Click Restore version.

The layout and all its languages go back to that version, and Shopify Flow uses it from the next email on. Your current layout stays in the list as a version, so a restore can be undone the same way.

Through the API

GET /api/v1/email-templates/:id/versions lists versions and POST /api/v1/email-templates/:id/versions/:version/restore restores one. The MCP tools are list_template_versions, get_template_version and restore_template_version.
