YateHSS/HLR, YateUCN and YateSMSC all offer a JSON API for configuration. You can use this API to:

  • configure the general network settings
  • set the SS7/Diameter settings of the server (both YateHSS/HLR and YateUCN)
  • set the SS7/SMPP settings for YateSMSC
  • define service (CS,PS,EPS,IMS) and SIM profiles (YateHSS/HLR)
  • manage subscribers (YateHSS/HLR)
  • request delivery of sms (YateSMSC)

The JSON API is accessed via the management IP address associated to each server. This IP address is provisioned by the MMI (Mobile Management Interface) or set by hand.

Request format

To use it, make a HTTPS POST request with "Content-Type" header "application/json" and "Mobile-API-Secret" header set to a pre-configured value.

Path for requests: https://ip_management/api.php

Requests have the following format:

{ "request": request_name, "params": {..} }

Depending on the params given you retrieve:

  • count of objects of a certain type
{} -- retrieve count 

In response you must look for "count" key if request is successful.

  • a part of the objects
{ "limit": , "offset": }  
  • specific objects by providing the id/name/other filtering criteria
{ "name": / "object_id": /.. } -- retrieve specific object by id/name/..

Response format

The API always returns a JSON object with the "Content-Type" set to "application/json" or "text/x-json".

In case of success:

{ "code": 0 } 
{ "code": 0, "object_name": [ {}, {} ] } // array of objects of the specific type. Ex: subscriber, pdn 
{ "code": 0, "count": } // count of objects of specific type when no parameters were specified

In case of an error:

{ "code": !0, "message": ... }

Turn to the next pages, JSON API for Configuration and JSON API for Subscriber Management to find out more about the supported requests and their parameters.

Error codes

There are two types of errors, as seen below.

HTTP errors

  • 405 (Method not allowed) - You didn't use HTTP POST method
  • 415 (Unsupported Media Type/Unparsable JSON content) - Content type is not "application/json" or "text/x-json" or JSON could not be decoded
