.. index:: Macro function;fn.request_get


* *fn.request_get*: Return in JSON format the response of an HTTP request. 
  The HTTP request must start with ``http://localhost``


Example request:  

::                                                                      
                                                                        
   {{ fn.request_get  http://localhost/api/data/Countries/properties }} 


The output can be assigned to a variable so that properties can be referenced.

Example with output snippet:

::
  
   http://localhost/api/data/Countries/properties


::

   
   {
       "meta": {
           "query": "/api/data/Countries/properties/?hierarchy=[hierarchy]&format=json"
       }, 
       "choices": [
           [
               "cli_on_prefix", 
               "cli_on_prefix"
           ], 
           [
               "country_name", 
               "country_name"
           ], 
           [
   ...


Example of instance output with GET request for an instance with ``[pkid]``:

::

   http://localhost/api/data/Countries/54e1de60edec65160652e402

::
  
   ...

     ], 
        "business_key": {
            "hierarchy": true, 
            "unique": [
                "country_name", 
                "iso_country_code"
            ]
        }, 
        "tagged_versions": []
    }, 
    "data": {
        "iso_country_code": "MEX", 
         "pstn_access_prefix": "9", 
         "pkid": "54e1de60edec65160652e403", 
         "default_user_locale": "English United States", 
         "network_locale": "United States", 
         "standard_access_prefix": "0", 
         "international_access_prefix": "00", 
         "country_name": "Mexico", 
         "international_dial_code": "52", 
         "emergency_access_prefix": "066", 
         "national_trunk_prefix": "01"
        }

.. index:: Macro function;fn.perform_http_get


* *fn.perform_http_get*: Given a URL parameter and optionally username and password parameters,
  return in HTTP status code of the HTTP request. 


  Example request:  

  ::                                                                      
                                                                        
     {{ fn.perform_http_get  http://<hostname> }} 

  Example request with additional parameters:  

  ::                                                                      
                                                                        
     {{ fn.perform_http_get  http://<hostname> <username> <password>}} 


  Example output:

  ::                                                                      
                                                                        
     200

  If the HTTP request raises an error (for example: not found, connection, timeout, and so on),
  this error will be returned.
