## What the `detail` says

The `detail` explains the occurrence; it can read, for example:

- WhatsApp rejected one of the template's variables.

## Handling it

The request is well-formed but its values are not accepted; fix them before retrying.

## Example

```json
{
  "type": "https://docs.nexafone.so/errors/whatsapp.template_param_invalid",
  "title": "Unprocessable Entity",
  "status": 422,
  "code": "whatsapp.template_param_invalid",
  "detail": "WhatsApp rejected one of the template's variables.",
  "requestId": "01J9Z8Q4TQ3W6M5V2X7Y8Z9A0B"
}
```

Match on `code`, never on `detail`: the wording may change. See [Problem Details](/v1/errors/).
