Response Examples

Example 1: GET operation response in XML format

The following is an example of OneData response to a GET request with the Accept header and content-type as application/xml.

<?xml version="1.0"?>
<COUNTRY>
<datarow>
<COUNTRY_ID>10</COUNTRY_ID>
<COUNTRY_NAME>SRILANKA</COUNTRY_NAME>
<STATE>
<datarow>
<STATE_ID>10</STATE_ID>
<STATE_NAME>COLOMBO</STATE_NAME>
<CONSTRAINT_COUNTRY_STATE>SRILANKA</CONSTRAINT_COUNTRY_STATE>
</datarow>
</STATE>
</datarow>
<datarow>
<COUNTRY_ID>1</COUNTRY_ID>
<COUNTRY_NAME>INDIA</COUNTRY_NAME>
<STATE>
<datarow>
<STATE_ID>1</STATE_ID>
<STATE_NAME>KARNATAKA</STATE_NAME>
<CONSTRAINT_COUNTRY_STATE>INDIA</CONSTRAINT_COUNTRY_STATE>
</datarow>
</STATE>
</datarow>
</COUNTRY>

Example 2: GET operation response in JSON format

The following is an example of OneData response to a GET request with the Accept header and content-type as application/json.

{
"COUNTRY": [
{
"COUNTRY_ID": "10",
"COUNTRY_NAME": "SRILANKA",
"STATE": [
{
"STATE_ID": "10",
"STATE_NAME": "COLOMBO",
"CONSTRAINT_COUNTRY_STATE": "SRILANKA"
}
]
},
{
"COUNTRY_ID": "1",
"COUNTRY_NAME": "INDIA",
"STATE": [
{
"STATE_ID": "1",
"STATE_NAME": "KARNATAKA",
"CONSTRAINT_COUNTRY_STATE": "INDIA"
}
]
}
]
}

Example 3: GET operation response in XML format with filtered data

The following is an example of OneData response to a GET request with the Accept header as application/xl, content-type as application/x-www-form-urlencoded, and the following filters:

filter={
"criterion" : [{
"criterion" : [{
"name" : "EMP_ID",
"operator" : "IN",
value" : "3"
}
]
}
}
}

The filter output is:

<EMP>
<datarow>
<EMP_ID>3</EMP_ID>
<EMP_NAME>EMP3</EMP_NAME>
<CONSTRAINT_COUNTRY_XML>IND</CONSTRAINT_COUNTRY_XML>
<CONSTRAINT_STATE>KARNATAKA</CONSTRAINT_STATE>
</datarow>
</EMP>

Example 4: GET operation response in JSON format with filtered data

The following is an example of OneData response to a GET request with the Accept header as application/json, content-type as application/x-www-form-urlencoded, and the following filters:

filter={
"criterion" : [{
"criterion" : [{
"name" : "EMP_ID",
"operator" : "IN",
"value" : "3"
}
]
}
]
}

The filter output is:

{
"EMP_7595": [
{
"EMP_ID": "3",
"EMP_NAME": "EMP3",
"CONSTRAINT_COUNTRY_XML": "IND",
"CONSTRAINT_STATE": "KARNATAKA"
}
]
}
