HTTP Status Codes

HTTP Status code

Means

1xx	Informational	It means the request has been received and the process is continuing
2xx	Success	It means the action was successfully received, understood, and accepted.
3xx	Redirection	It means further action must be taken in order to complete the request.
4xx	Client Error	It means the request contains incorrect syntax or cannot be fulfilled
5xx	Server Error	It means the server failed to fulfill an apparently valid request.

102	Processing	An interim response used to inform the client that the server has accepted the complete request, but has not yet completed it.
103	Early Hints	Indicates to the client that the server is likely to send a final response with the header fields included in the informational response.
