API Request Overview

In the URI of each method in this document we write “V#” instead of V1, since when moving from Version to Version sometimes we forgot to update it in the document. So to make our life easier, V# covers the Latest version.

Standard API Request Headers

Approved Standard Headers are documented at https://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html

#Header

Required?

Description
1Accept
YES

Specifies the format of the response message body. 

Structured text message payloads are required to support application/json.  No other format is permitted.  As they are the only supported format, the accept header is not relevant for those requests.
2Content-type
 YES
 Determines the format of the request content. Only application/json is supported.

Error Handling

Note that, in some scenarios, Client may receive error responses that originate from the network layers.  The content of these responses will not conform to the exception schema specified here.

#Header

Required?

Description
1

errorCode

YES

Code which identifies the error

2

errorMessage

YES

Human readable text

Error Example:

{

         "errorCode": 402,

         "errorMessage": “Mandatory fields are missing”

}

Here is the list of HTTP status code:

HTTP ErrorerrorCodeerrorMessageDetails
202 Accepted510No E2T Instance available. The existing RAN can't associated with any available E2T Instance. When E2T will be identified, this RAN will be served.
511No Routing Manager Available

Currently there is connectivity to the Routing Manager. E2M will try later.

400 Bad Request


401corrupted jsonCan't parse the payload of the body
402validation errorE.G: Mandatory fields are missing or invalid (The value isn't according expected); 
403 Activity <activity name> rejected. RAN current state <state> does not allow its executionE.G: Reset  request is sent when state isn't Connected
405command already in progressE.G: 2 parallel Red Button were sent

404 Not Found



If the resource name doesn't exist (e.g.: nodec instead of nodeb) - the system returns HTTP Error 404  with "404 page not found" text.
404resource not foundThe classic 404 - Resource ID  doesn't exist in the system
406No RAN in Connected Statee.g.: RAN Health Check and no one in Connected
415 Unsupported Media Type415Header validation errorIn case there is a body  and header  application/json is missing - error.

500 Internal Server Error

In addition, there are 2 Basic HTTP error happens before the handlers are calling:

  • HTTP Error 404 Not Found (Body is empty) - The Resource name isn't found (e.g.: Call /v#/nodec instead of /v#/nodeb)
  • HTTP Error 405 Method Not Allowed (Body is empty) - Wrong HTTP VERB to known resource name *e.g.: Call  HTTP GET v#/nodeb/x2-setup)
