Status codes

This is a list of Hypertext Transfer Protocol (HTTP) response status codes. Status codes are issued by a server in response to a client's request made to the server. All HTTP response status codes are separated into five classes. The first digit of the status-code defines the class of response, while the last two digits do not have any classifying or categorization role.

There are five classes defined by the standard:

• 1xx informational response – the request was received, continuing process

• 2xx successful – the request was successfully received and accepted

• 3xx redirection – further action needs to be taken in order to complete the request

• 4xx client error – the request contains bad syntax or cannot be fulfilled

• 5xx server error – the server failed to fulfil an apparently valid request

The standard error response is provided in the below sample format:

{
  "errors": 
  [
    {
      "status": "400",
      "source": { "pointer": "/data/attributes/firstName" },
      "title":  "Bad Request",
      "detail": "First name must contain at least three characters."
    }
  ]
}
