--- title: Notecard Error and Status Codes description: Notecard API responses often include a set of error and status codes denoted by curly braces, e.g. `{sync-begin}`. These codes are static and will persist across API versions. source_url: https://dev.blues.io/support/notecard-error-and-status-codes/ canonical_url: https://dev.blues.io/support/notecard-error-and-status-codes/ markdown_url: https://dev.blues.io/support/notecard-error-and-status-codes.md --- # Notecard Error and Status Codes Notecard API responses may include one or more error or status codes denoted by curly braces, e.g. `{sync-begin}`. These codes are static and persist across API versions. > **Note:** > > 1. The **Related APIs** column refers to Notecard API requests whose response may contain this code, either as an `err` returned by the request, or as part of the `status` reported by the request. > > 2. This list is a best-effort guide, not an exhaustive guarantee. Some error/status codes could in principle appear in other API responses through indirect code paths in the Notecard firmware. > > 3. If you encounter a code not on this list, or have any other technical questions, please reach out on the [Blues Developer Forum](https://discuss.blues.com/) for assistance. | Code | Definition | Resolution | Related APIs | | ---------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `{address-assigned}` | Successful DHCP resolution and IP address assigned. | | [`card.wifi`](https://dev.blues.io/api-reference/notecard-api/card-requests.md#card-wifi) [`card.wireless`](https://dev.blues.io/api-reference/notecard-api/card-requests.md#card-wireless) [`hub.sync.status`](https://dev.blues.io/api-reference/notecard-api/hub-requests.md#hub-sync-status) | | `{auth}` | Notehub unable to authenticate Notecard. | Check accompanying status for more details - if the situation persists [contact Blues](https://discuss.blues.com/). | [`hub.status`](https://dev.blues.io/api-reference/notecard-api/hub-requests.md#hub-status) [`hub.sync`](https://dev.blues.io/api-reference/notecard-api/hub-requests.md#hub-sync) [`hub.sync.status`](https://dev.blues.io/api-reference/notecard-api/hub-requests.md#hub-sync-status) | | `{auth-retry}` | Notehub authentication failed.
