# E28026 — AMBBusinessNameRequired

The business needs a display name.

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

## What to do

Send the brand name customers see on the conversation. It is what the console and the landing page show, so an empty one leaves an operator with nothing to identify the thread by.
