Error codes

Last updated June 26th, 2024

The Knox E-FOTA API uses the conventional HTTP response code to indicate the success or failure of a request. A 2XX response code indicates success, a 4XX response code indicates an error given the inputs of the request, and a 5XX response code indicates a failure with the Knox E-FOTA platform.

Standard HTTP error codes

The following table lists the most common HTTP error responses:

Code Name Description
200 Success The request was successfully received.
400 Bad request The client has issued an invalid request. Verify your request (ex. check validation errors in your request load).
401 Unauthorized Authorization for the API is required, but the request has not been authenticated.
403 Forbidden The request has been authenticated but does not have the appropriate permissions, or the requested resource not be found.
404 Not found The requested path or the specified user does not exist.
409 Conflict The request could not be completed due to a conflict with the current state of the target resource.
500 Server error An error has occurred on the server. Please try again later.

Knox E-FOTA error codes

Knox E-FOTA specifies custom error codes for each endpoint. The custom error codes are returned under HTTP error code 400, while WRONG_ACCESS errors are returned under HTTP error code 403.

For each user

The super admin of each tenant will receive tokens through Knox Cloud API key generation. Once the API key is generated, all users under this tenant will be able to call the Knox E-FOTA API using the token. Each admin under the same tenant will be able to make API requests at a maximum of 25 calls every second.

For each API key

The API token can be used up to a maximum of 25 API calls every second.
