The Open Data Protocol (OData) is a data access protocol built on core protocols like HTTP and commonly accepted methodologies like REST for the web. There are various kinds of libraries and tools can be used to consume OData services. But for beginners and those who want to write their own libraries, the pure HTTP requests and responses are also very important. This documentation will not cover every feature details for OData V4 services but will try to cover various typical scenarios. If you want to have a more detailed understanding, please refer to OData Documentation.

You can now use the Postman collections to learn OData in an interactive way.

Please be noted

OData services support requests for data via HTTP GET requests.

Requesting Entity Collections

The request below returns the the collection of Person People.
GET serviceRoot/People

Response Payload

{% highlight javascript%} { "@odata.context": "serviceRoot/$metadata#People", "@odata.nextLink": "serviceRoot/People?%24skiptoken=8", "value": [ { "@odata.id": "serviceRoot/People('russellwhyte')", "@odata.etag": "W/"08D1694BD49A0F11"", "@odata.editLink": "serviceRoot/People('russellwhyte')", "UserName": "russellwhyte", "FirstName": "Russell", "LastName": "Whyte", "Emails": [ "Russell@example.com", "Russell@contoso.com" ], "AddressInfo": [ { "Address": "187 Suffolk Ln.", "City": { "CountryRegion": "United States", "Name": "Boise", "Region": "ID" } } ], "Gender": "Male", "Concurrency": 635404796846280400 }, ...... , { "@odata.id": "serviceRoot/People('keithpinckney')", "@odata.etag": "W/"08D1694BD49A0F11"", "@odata.editLink": "serviceRoot/People('keithpinckney')", "UserName": "keithpinckney", "FirstName": "Keith", "LastName": "Pinckney", "Emails": [ "Keith@example.com", "Keith@contoso.com" ], "AddressInfo": [], "Gender": "Male", "Concurrency": 635404796846280400 } ] } {% endhighlight %}

Requesting an Individual Entity by ID

The request below returns an individual entity of type Person by the given UserName "russellwhyte"
GET serviceRoot/People('russellwhyte')

Response Payload

{% highlight javascript%} { "@odata.context": "serviceRoot/$metadata#People/$entity", "@odata.id": "serviceRoot/People('russellwhyte')", "@odata.etag": "W/"08D1694BF26D2BC9"", "@odata.editLink": "serviceRoot/People('russellwhyte')", "UserName": "russellwhyte", "FirstName": "Russell", "LastName": "Whyte", "Emails": [ "Russell@example.com", "Russell@contoso.com" ], "AddressInfo": [ { "Address": "187 Suffolk Ln.", "City": { "CountryRegion": "United States", "Name": "Boise", "Region": "ID" } } ], "Gender": "Male", "Concurrency": 635404797346655200 } {% endhighlight %}

Requesting an Individual Property

To address an entity property clients append a path segment containing property name to the URL of the entity. If the property has a complex type, properties of that value can be addressed by further property name composition.
First let's take a look at how to get a simple property. The request below returns the Name property of an Airport.

GET serviceRoot/Airports('KSFO')/Name

Response Payload

{% highlight javascript%} { "@odata.context": "serviceRoot/$metadata#Airports('KSFO')/Name", "value": "San Francisco International Airport" } {% endhighlight %}

Then let's see how to get a property value of a complex type. The request below returns the Address of the complex type Location in an Airport.
GET serviceRoot/Airports('KSFO')/Location/Address

Response Payload

{% highlight javascript%} { "@odata.context": "serviceRoot/$metadata#Airports('KSFO')/Location/Address", "value": "South McDonnell Road, San Francisco, CA 94128" } {% endhighlight %}

Requesting an Individual Property Raw Value

To address the raw value of a primitive property, clients append a path segment containing the string $value to the property URL. The request below returns the raw value of property Name of an Airport.
GET serviceRoot/Airports('KSFO')/Name/$value

Response Payload

{% highlight javascript%} San Francisco International Airport {% endhighlight %}

OData supports various kinds of query options for querying data. This section will help you go through the common scenarios for these query options.

System Query Option $filter

The $filter system query option allows clients to filter a collection of resources that are addressed by a request URL. The expression specified with $filter is evaluated for each resource in the collection, and only items where the expression evaluates to true are included in the response.

Basic predicates, built-in functions

There are several kinds of basic predicates and built-in functions for $filter, including logical operators and arithmetic operators. For more detailed information, please refer to OData V4 URL Conventions Document. The request below using $filter to get people with FirstName "Scott".
GET serviceRoot/People?$filter=FirstName eq 'Scott'

Response Payload

{% highlight javascript%} { "@odata.context": "serviceRoot/$metadata#People", "value": [ { "@odata.id": "serviceRoot/People('scottketchum')", "@odata.etag": "W/"08D1694C7E510464"", "@odata.editLink": "serviceRoot/People('scottketchum')", "UserName": "scottketchum", "FirstName": "Scott", "LastName": "Ketchum", "Emails": [ "Scott@example.com" ], "AddressInfo": [ { "Address": "2817 Milton Dr.", "City": { "CountryRegion": "United States", "Name": "Albuquerque", "Region": "NM" } } ], "Gender": "Male", "Concurrency": 635404799693620400 } ] } {% endhighlight %}

Filter on Complex Type

$filter can also work on complex type. The request below returns airports with "San Francisco" contained in its Address. And Address is property of complex type Location.

GET serviceRoot/Airports?$filter=contains(Location/Address, 'San Francisco')

Response Payload

{% highlight javascript%} { "@odata.context": "serviceRoot/$metadata#Airports", "value": [ { "@odata.id": "serviceRoot/Airports('KSFO')", "@odata.editLink": "serviceRoot/Airports('KSFO')", "IcaoCode": "KSFO", "Name": "San Francisco International Airport", "IataCode": "SFO", "Location": { "Address": "South McDonnell Road, San Francisco, CA 94128", "City": { "CountryRegion": "United States", "Name": "San Francisco", "Region": "California" }, "Loc": { "type": "Point", "coordinates": [ -122.374722222222, 37.6188888888889 ], "crs": { "type": "name", "properties": { "name": "EPSG:4326" } } } } } ] } {% endhighlight %}

Filter on Enum Properties

The request below returns all female People of entity type Person. The Gender is a property of Enum type.
GET serviceRoot/People?$filter=Gender eq Microsoft.OData.SampleService.Models.TripPin.PersonGender'Female'

Response Payload

{% highlight javascript%} { "@odata.context": "serviceRoot/$metadata#People", "@odata.nextLink": "serviceRoot/People?%24filter=Gender+eq+Microsoft.OData.SampleService.Models.TripPin.PersonGender%27Female%27&%24skiptoken=8", "value": [ { "@odata.id": "serviceRoot/People('elainestewart')", "@odata.etag": "W/"08D1694CCFB34453"", "@odata.editLink": "serviceRoot/People('elainestewart')", "UserName": "elainestewart", "FirstName": "Elaine", "LastName": "Stewart", "Emails": [ "Elaine@example.com", "Elaine@contoso.com" ], "AddressInfo": [], "Gender": "Female", "Concurrency": 635404801059013800 }, ...... , { "@odata.id": "serviceRoot/People('ursulabright')", "@odata.etag": "W/"08D1694CCFB34453"", "@odata.editLink": "serviceRoot/People('ursulabright')", "UserName": "ursulabright", "FirstName": "Ursula", "LastName": "Bright", "Emails": [ "Ursula@example.com", "Ursula@contoso.com" ], "AddressInfo": [], "Gender": "Female", "Concurrency": 635404801059013800 } ] } {% endhighlight %}

Nested Filter in Expand

Updatable OData services support Create, Update and Delete operation for some or all exposed entities.

Create an Entity

To create an entity in a collection, the client sends a POST request to that collection's URL. The POST body MUST contain a single valid entity representation. The request below creates a Person which contains complex type and collection property.

Functions and Actions

OData supports custom operations (Actions and Functions). Functions are operations exposed by an OData service that MUST return data and MUST have no observable side effects. Actions are operations exposed by an OData service that MAY have side effects when invoked. Functions and actions both MAY bound to an entity type, primitive type, complex type, or a collection.

Invoking Unbound Functions

The function below returns the nearest airport with the input geography point.
GET serviceRoot/GetNearestAirport(lat = 33, lon = -118)
