# E15012 — WhatsAppTemplateVersionImmutable

This version is not the draft and cannot be changed directly.

- **HTTP status**: `422`
- **Type**: `validation_error`
- **Name**: `WhatsAppTemplateVersionImmutable`

## What to do

Only the draft accepts content changes. Edit the template's draft and submit it as a new version; the one exception is re-driving a language that failed to submit or was archived on the version you last submitted, which you can resubmit directly.
