## What the `detail` says

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

- Meta did not change calling for this number. Check the number in WhatsApp Manager and try again.

## Handling it

An upstream service (such as WhatsApp) failed; retry later or follow the message.

## Example

```json
{
  "type": "https://docs.nexafone.so/errors/whatsapp_calling_not_changed",
  "title": "Bad Gateway",
  "status": 502,
  "code": "whatsapp_calling_not_changed",
  "detail": "Meta did not change calling for this number. Check the number in WhatsApp Manager and try again.",
  "requestId": "01J9Z8Q4TQ3W6M5V2X7Y8Z9A0B"
}
```

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