# E15076 — WhatsAppTemplateLanguageRequired

This template requires the send to name a language.

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

## What to do

The template sets `language_source_required`, so it will not fall back to its `default_language`: it holds a copy per language and expects you to choose the one for this recipient. Name a `language` from the template's `available_languages`. If every recipient should get the same copy, clear `language_source_required` on the template instead.
