HTTP Methods
This protocol uses the four methods of the HTTP protocol:
- GET, to retrieve values from the database. It’s idempotent that means no changes to the database happen. Remember that in IE6 the URL can be maximum of 2,083 characters. Other browsers supports longer URLs, but if you want to stay compatible with all limit to 2,083 characters
- POST, to insert values into the database
- PUT, to change values into the database
- DELETE, to delete values from the database
When using POST and PUT the following are important when preparing the contents of the post message:
- Always have the content type set to “application/json” or “application/xml”
- Where data or data structure is involved the content is in JSON format
- For OrientDB SQL or Gremlin the content itself is just text
Headers
All the requests must have these 2 headers:
'Accept-Encoding': 'gzip,deflate'
'Content-Length': <content-length>
`
Where the <content-length>
is the length of the request’s body.
Syntax
The REST API is very flexible, with the following features:
- Data returned is in JSON format
- JSONP callback is supported
- Support for http and https connections
- The API itself is case insensitive
- API can just be used as a wrapper to retrieve (and control) data through requests written in OrientDB SQL or Gremlin
- You can avoid using
#
for RecordIDs in URLs, if you prefer. Just drop the#
from the URL and it will still work
The REST syntax used is the same for all the four HTTP methods:
Syntax: http://<server>:<port>/<command>/[<database>/<arguments>]
Results are always in JSON format. Support for ‘document’ object types is through the use of the attribute @type : 'd'
. This also applies when using inner document objects.
Example:
{
"@type" : "d",
"Name" : "Test",
"Data" : { "@type": "d",
"value": 0 },
"@class" : "SimpleEntity"
}
JSONP is also supported by adding a callback parameter to the request (containing the callback function name).
Syntax: http://<server>:<port>/<command>/[<database>/<arguments>]?callback=<callbackFunctionName>
Commands are divided in two main categories:
- Server commands, such as to know server statistics and to create a new database
- Database commands, all the commands against a database
Authentication and security
All the commands (but the Disconnect need a valid authentication before to get executed. The OrientDB Server checks if the Authorization HTTP header is present, otherwise answers with a request of authentication (HTTP error code: 401).
The HTTP client (or the Internet Browser) must send user and password using the HTTP Base authentication. Password is encoded using Base64 algorithm. Please note that if you want to encrypt the password using a safe mode take in consideration to use SSL connections.
Server commands use the realm “OrientDB Server”, while the database commands use a realm per database in this form: "OrientDB db-<database>"
, where <database>
is the database name. In this way the Browser/HTTP client can reuse user and password inserted multiple times until the session expires or the “Disconnect” is called.
On first call (or when the session is expired and a new authentication is required), OrientDB returns the OSESSIONID parameter in response’s HTTP header. On further calls the client should pass this OSESSIONID header in the requests and OrientDB will skip the authentication because a session is alive. By default sessions expire after 300 seconds (5 minutes), but you can change this configuration by setting the global setting: network.http.sessionExpireTimeout
JSON data type handling and Schema-less mode
Since OrientDB supports also schema-less/hybrid modes how to manage types? JSON doesn’t support all the types OrientDB has, so how can I pass the right type when it’s not defined in the schema?
The answer is using the special field “@fieldTypes” as string containing all the field types separated by comma. Example:
{ "@class":"Account", "date": 1350426789, "amount": 100.34,
"@fieldTypes": "date=t,amount=c" }
The supported special types are:
- ‘f’ for float
- ‘c’ for decimal
- ‘l’ for long
- ‘d’ for double
- ‘b’ for byte and binary
- ‘a’ for date
- ‘t’ for datetime
- ‘s’ for short
- ‘e’ for Set, because arrays and List are serialized as arrays like [3,4,5]
- ‘x’ for links
- ‘n’ for linksets
- ‘z’ for linklist
- ‘m’ for linkmap
- ‘g’ for linkbag
- ‘u’ for custom
Keep-Alive
Attention: OrientDB HTTP API utilizes Keep-Alive feature for better performance: the TCP/IP socket is kept open avoiding the creation of a new one for each command. If you need to re-authenticate, open a new connection avoiding to reuse the already open one. To force closing put “Connection: close” in the request header.

Cluster
GET - Cluster
Where the primary usage is a document db, or where the developer wants to optimise retrieval using the clustering of the database, use the CLUSTER command to browse the records of the requested cluster.
Syntax: http://<server>:[<port>]/cluster/<database>/<cluster-name>/
Where <limit>
is optional and tells the maximum of records to load. Default is 20.
Example
HTTP GET request: http://localhost:2480/cluster/demo/Address
HTTP response:
{ "schema": {
"id": 5,
"name": "Address"
},
"result": [{
"_id": "11:0",
"_ver": 0,
"@class": "Address",
"type": "Residence",
"street": "Piazza Navona, 1",
"city": "12:0"
}
...
Command
POST - Command
Execute a command against the database. Returns the records affected or the list of records for queries. Command executed via POST can be non-idempotent (look at Query).
Syntax: http://<server>:[<port>]/command/<database>/<language>[/<command-text>[/limit[/<fetchPlan>]]]
The content can be <command-text>
or starting from v2.2 a json containing the command and parameters:
- by parameter name:
{"command":<command-text>, "parameters":{"<param-name>":<param-value>} }
- by parameter position:
{"command":<command-text>, "parameters":[<param-value>] }
Where:
<language>
is the name of the language between those supported. OrientDB distribution comes with “sql” and GraphDB distribution has both “sql” and “gremlin”command-text
is the text containing the command to executelimit
is the maximum number of record to return. Optional, default is 20fetchPlan
is the fetching strategy to use. For more information look at Fetching Strategies. Optional, default is *:1 (1 depth level only)
The command-text can appear in either the URL or the content of the POST transmission. Where the command-text is included in the URL, it must be encoded as per normal URL encoding. By default the result is returned in JSON. To have the result in CSV, pass “Accept: text/csv” in HTTP Request.
Starting from v2.2, the HTTP payload can be a JSON with both command to execute and parameters. Example:
Execute a query passing parameters by name:
{
"command": "select from V where name = :name and city = :city",
"parameters": {
"name": "Luca",
"city": "Rome"
}
}
Execute a query passing parameters by position:
{
"command": "select from V where name = ? and city = ?",
"parameters": [ "Luca", "Rome" ]
}
Read the SQL section or the Gremlin introduction for the type of commands.
Example
HTTP POST request: http://localhost:2480/command/demo/sql
content: update Profile set online = false
HTTP response: 10
Or the same:
HTTP POST request: http://localhost:2480/command/demo/sql/update Profile set online = false
HTTP response: 10
Extract the user list in CSV format using curl
curl --user admin:admin --header "Accept: text/csv" -d "select from ouser" "http://localhost:2480/command/GratefulDeadConcerts/sql"
Batch
POST - Batch
Executes a batch of operations in a single call. This is useful to reduce network latency issuing multiple commands as multiple requests. Batch command supports transactions as well.
Syntax: http://<server>:[<port>]/batch/<database>
Content: { “transaction” :
Returns: the result of last operation.
Where: type can be:
- ‘c’ for create, ‘record’ field is expected.
- ‘u’ for update, ‘record’ field is expected.
- ‘d’ for delete. The ‘@rid’ field only is needed.
- ‘cmd’ for commands (Since v1.6). The expected fields are:
- ‘language’, between those supported (sql, gremlin, script, etc.)
- ‘command’ as the text of the command to execute
- ‘script’ for scripts (Since v1.6). The expected fields are:
- ‘language’, between the language installed in the JVM. Javascript is the default one, but you can also use SQL (see below)
- ‘script’ as the text of the script to execute
Example
{ "transaction" : true,
"operations" : [
{ "type" : "u",
"record" : {
"@rid" : "#14:122",
"name" : "Luca",
"vehicle" : "Car"
}
}, {
"type" : "d",
"record" : {
"@rid" : "#14:100"
}
}, {
"type" : "c",
"record" : {
"@class" : "City",
"name" : "Venice"
}
}, {
"type" : "cmd",

"command" : "create edge Friend from #10:33 to #11:33"
}, {
"type" : "script",
"language" : "javascript",
"script" : "orient.getGraph().createVertex('class:Account')"
}
]
}
SQL batch
{ "transaction" : true,
"operations" : [
{
"type" : "script",
"language" : "sql",
"script" : [ "LET account = CREATE VERTEX Account SET name = 'Luke'",
"LET city = SELECT FROM City WHERE name = 'London'",
"CREATE EDGE Lives FROM $account TO $city RETRY 100" ]
}
]
}
Function
POST and GET - Function
Executes a server-side function against the database. Returns the result of the function that can be a string or a JSON containing the document(s) returned.
The difference between GET and POST method calls are if the function has been declared as idempotent. In this case can be called also by GET, otherwise only POST is accepted.
Syntax: http://<server>:[<port>]/function/<database>/<name>[/<argument>*]<server>
Where
<name>
is the name of the function<argument>
, optional, are the arguments to pass to the function. They are passed by position.
Creation of functions, when not using the Java API, can be done through the Studio in either Orient DB SQL or Java – see the OrientDB Functions page.

}
Index
NOTE: Every single new database has the default manual index called “dictionary”.
GET - Index
Retrieve a record looking into the index.
Syntax: http://<server>:[<port>]/index/<index-name>/<key>
Example
HTTP GET request: http://localhost:2480/dictionary/test
HTTP response:
{

Syntax: http://<server>:[<port>]/index/<index-name>/<key>
Example
HTTP DELETE request: http://localhost:2480/dictionary/test
HTTP response: No response.
Query
GET - Query
Execute a query against the database. Query means only idempotent commands like SQL SELECT and TRAVERSE. Idempotent means the command is read-only and can’t change the database. Remember that in IE6 the URL can be maximum of 2,083 characters. Other browsers supports longer URLs, but if you want to stay compatible with all limit to 2,083 characters.
Syntax: http://<server>:[<port>]/query/<database>/<language>/<query-text>[/<limit>][/<fetchPlan>]
Where:
<language>
is the name of the language between those supported. OrientDB distribution comes with “sql” only. Gremlin language cannot be executed with query because it cannot guarantee to be idempotent. To execute Gremlin use command instead.query-text
is the text containing the query to executelimit
is the maximum number of record to return. Optional, default is 20fetchPlan
is the fetching strategy to use. For more information look at Fetching Strategies. Optional, default is *:1 (1 depth level only)
Other key points:
