Design principles

Versioning

The Okta API is a versioned API. Okta reserves the right to add new parameters, properties, or objects to the API without advance notice. These updates are considered non-breaking and the compatibility rules below should be followed to ensure your application does not break. Breaking changes such as removing or renaming a property will be released as a new version of the API. Okta will provide a migration path for new versions of APIs and will communicate timelines for end-of-life when deprecating APIs.

Do not consume any Okta API unless it is documented on this site. All undocumented endpoints should be considered private, subject to change without notice, and not covered by any agreements.

Compatibility rules for input parameters

• Requests are compatible irrespective of the order in which the query parameters appear.
• Requests are compatible irrespective of the order in which the properties of the JSON parameters appear.
• New query parameters may be added to future versions of requests.
• Existing query parameters cannot be removed from future versions of requests.
• Existing properties cannot be removed from the JSON parameters in future versions of requests.

Compatibility rules for JSON responses

• Responses are compatible irrespective of the order in which the properties appear.
• New properties may be added to future versions of the response.
• Existing properties cannot be removed from future versions of the response.
• Properties with null values may be omitted by responses.

URL namespace

All URLs listed in the documentation should be preceded with your organization's subdomain (tenant) and API version: https://${yourOktaDomain}/api/${apiversion} The API version is currently v1.

Note: All API requests must use the HTTPS scheme.

Media types

Note: JSON responses, including errors, may contain user input. To help prevent potential cross-site scripting attacks, make sure to properly escape all values before use in a browser or any HTML context.

The API currently supports only JSON as an exchange format. Be sure to set both the Content-Type and Accept headers for every request as application/json.

All Date objects are returned in ISO 8601 format:

YYYY-MM-DDTHH:mm:ss.SSSZ

Character sets

Okta supports a subset of the UTF-8 specification. Specifically, any character that can be encoded in three bytes or less is supported. BMP characters and supplementary characters that must be encoded using four bytes aren't supported at this time.

Special characters

Certain query parameters, such as when filtering, require percent encoding to ensure correct interpretation of special characters. See Percent Encoding.

Consider the following example:

filter=lastUpdated gt "2013-06-01T00:00:00.000Z"

This is encoded to the following:

filter=lastUpdated%20gt%20%222013-06-01T00:00:00.000Z%22

Note: Don't encode delimiters, which are essential parts of the request structure. Common examples of this include the question mark before the query (like ?name) and https:// at the start of a URL. Incorrectly encoding delimiters can result in an error. See Encode Query and Special characters and delimiters in the help documentation.

HTTP verbs

Where possible, the Okta API strives to use appropriate HTTP verbs for each action.

GET

Used for retrieving objects

POST

Used for creating objects or performing custom actions (such as user lifecycle operations). For POST requests with no body param, set the Content-Length header to zero.

PUT

Used for replacing objects or collections. For PUT requests with no body param, set the Content-Length header to zero.

DELETE

Used for deleting objects

Note: Any PUT or POST request without a Content-Length header or a body returns a 411 error. To get around this, include a Content-Length: 0 header.

Client request context

Okta derives the client request context directly from the HTTP request headers and client TCP socket. The request context is used to evaluate policies such as Global Session Policy and provide client information for troubleshooting and auditing purposes.

User Agent

Okta supports the standard User-Agent HTTP header to identify the user's browser or application. Always send a User-Agent string to uniquely identify your client application and version, for example: Oktaprise/1.1.

Note: If your application is acting as a gateway or proxy, you should forward the User-Agent of the originating client with your API requests.

Format a User-Agent string

Ensure that the User-Agent string that your app constructs is in the correct format so that Okta can parse the OS and Browser fields. Okta can correctly parse User-Agent strings that contain browser and system information, platform details, and any extensions.

Use a template to format the string

We recommend that you use a template like the following to format the User-Agent string:

User-Agent: Mozilla/5.0 (<system-information>) <platform> (<platform-details>) <extensions>

Okta recommends making test API calls, then checking for the related entries in the System Log. Testing helps you ensure that Okta can parse both the OS and Browser fields from the User-Agent header that is passed by your application.

If the OS and/or Browser fields come back as Unknown in the System Log, ensure that certain string values (see below) are present in the User-Agent string so that the OS and Browser are detected:

Note: For some Chrome examples, see User-Agent strings.

Pass a hint about the browser

Add browser information such as chrome or safari to the User-Agent string.

Pass operating system information

• iOS: Include the words apple or ios and at least one of these values: iphone , ipad , ipod , ipad .
• Android: Include the word android , which infers that Android is the operating system.

IP address

The public IP address of your application is automatically used as the client IP address for your request. Okta supports the standard X-Forwarded-For HTTP header to forward the originating client's IP address if your application is behind a proxy server or acting as a sign-in portal or gateway.

Note: The public IP address of your trusted web application must be a part of the allowlist in your org's network security settings as a trusted proxy to forward the user agent's original IP address with the X-Forwarded-For HTTP header.

Accept Language

The Accept-Language HTTP header advertises which languages the client is able to understand, for example Accept-Language: en-US. Include the header if it is available.

Device Fingerprint

The X-Device-Fingerprint HTTP header supplies the device fingerprint used in an authentication request.

Errors

Note: JSON responses, including errors, may contain user input. To help prevent potential cross-site scripting attacks, ensure to properly escape all values before use in a browser or any HTML context.

All successful requests return a 200 status if there is content to return or a 204 status if there is no content to return.

All requests that result in an error return the appropriate 4xx or 5xx error code with a custom JSON error object:

• errorCode : A code that is associated with this error type
• errorLink : A link to documentation with a more detailed explanation of the error (not yet implemented and is currently the same value as the errorCode )
• errorSummary : A natural language explanation of the error
• errorId : An ID that identifies this request. These IDs are mapped to the internal error on the server side to assist in troubleshooting.

{
    "errorCode": "E0000001",
    "errorSummary": "Api validation failed",
    "errorLink": "E0000001",
    "errorId": "oaeHfmOAx1iRLa0H10DeMz5fQ",
    "errorCauses": [
        {
            "errorSummary": "login: An object with this field already exists in the current organization"
        }
    ]
}

See Error Codes for a list of API error codes.

Note: Only the errorCode property is supported for runtime error flow control. The errorSummary property is only intended for troubleshooting and may change over time.

Pagination

Requests that return a list of objects may support pagination. Pagination is based on a cursor and not on page number. The cursor is opaque to the client and specified in either the before or after query parameter. For some objects, you can also set a custom page size with the limit parameter.

Link header

Pagination links are included in the Link header of responses. It is important to follow these Link header values instead of constructing your own URLs as query parameters or cursor formats may change without notice.

HTTP/1.1 200 OK
link: <https://{yourOktaDomain}/api/v1/logs?limit=20>; rel="self"
link: <https://{yourOktaDomain}/api/v1/logs?limit=20&after=1627500044869_1>; rel="next"

The possible rel values are:

When you first make an API call and get a cursor-paged list of objects, the end of the list is the point where you don't receive another next link value with the response. This holds true for all cases, except for the System Log API where the next link always exists in System Log polling queries. A polling query is defined as an ASCENDING query with an empty or absent until parameter, providing a stream of data.

Filter

Filtering allows a requestor to specify a subset of objects to return and is often needed for large collection objects such as Users. While filtering semantics are standardized in the Okta API, not all objects in the Okta API support filtering. When filtering is supported for an object, the filter URL query parameter contains a filter expression.

The expression language that is used in the filter and search parameters supports references to JSON attributes and literals. The literal values can be strings enclosed in double quotes, numbers, date times enclosed in double quotes, and Boolean values (for example, true or false). String literals must be valid JSON strings.

The attribute names are case-sensitive while attribute operators are case-insensitive. For example, the following two expressions evaluate to the same logical value:

filter=firstName Eq "john"

filter=firstName eq "john"

The filter and search parameters must contain at least one valid boolean expression. Each expression must contain an attribute name followed by an attribute operator and an optional value. You can combine multiple expressions using two logical operators. Furthermore, you can group expressions together using (). If your expression contains special characters, make sure you encode the parameter.

Note: Each object in the Okta API defines what attributes and operators are supported for the expression. See object-specific documentation for more information.

Operators

Most of the operators listed in the SCIM Protocol Specification are supported:

Note: Some objects don't support all the listed operators.

Note: The ne (not equal) operator isn't supported for some objects, but you can obtain the same result by using lt ... or ... gt. For example, to see all user agents except for "iOS", use (client.userAgent.os lt "iOS" or client.userAgent.os gt "iOS").

Note: All Date values use the ISO 8601 format YYYY-MM-DDTHH:mm:ss.SSSZ.

Attribute operators

Logical operators

Filters must be evaluated using the standard order of operations. Attribute operators have the highest precedence, followed by the grouping operator (for example, parentheses), followed by the logical AND operator, followed by the logical OR operator.

Hypermedia

Objects in the Okta API use hypermedia for discoverability. Hypermedia enables API clients to navigate objects by following links like a web browser instead of hard-coding URLs in your application. Links are identified by link relations that are named keys. Link relations describe what objects are available and how API clients can interact with them. Each object may publish a set of link relationships based on the state of the object. For example, the status of a user in the User API governs which lifecycle operations are permitted. Only the permitted operations are published as lifecycle operations.

The Okta API incorporates JSON Hypertext Application Language or HAL format as the foundation for hypermedia discoverability. HAL provides a set of conventions for expressing hyperlinks in JSON responses that represent two simple concepts: Resources and Links.

Note: The HAL-specific media type application/hal+json isn't currently supported as a formal media type for content negotiation. Use the standard application/json media type. As we get more experience with the media format, we may add support for the media type.

Links

Objects with property names that are link relation types (as defined by RFC8288) have values that are either a Link object or an array of Link objects. Link objects contain the following:

• A target URI
• The name of the link relation ( rel )
• Other optional properties to help with deprecation, object state or lifecycle management, content negotiation, and so on.
• Links are implicitly of media type application/json . Other media types are only returned in cases where the link isn't an API endpoint.

Note: An object may have multiple links that share the same link relation as shown below for the "logo" link.

{
    "_links": {
        "logo": [
            {
              "name": "medium",
              "href": "https://{yourOktaDomain}/assets/img/logos/groups/active_directory-medium.b3959116154f9d44bd4d0f6b2ae31ea6.png",
              "type": "image/png"
            },
            {
              "name": "large",
              "href": "https://{yourOktaDomain}/assets/img/logos/groups/active_directory-large.0e7a58559ac90c4bbc7b33fa14018c50.png",
              "type": "image/png"
            }
         ],
        "self": { "href": "/example_resource" },
        "next": { "href": "/page=2" }
    }
}

Links in collections

HAL links that are returned in a collection of resources may not reflect the total set of operations that are possible on that resource. For example, in a user collection, links to indicate that a given user can be unlocked may not be returned and, if returned, may not reflect the correct user state.

Search and list operations are intended to find matching resources and their identifiers. If you intend to search for a resource and then modify its state or make a lifecycle change, the correct pattern is to first retrieve the resource by id using the self link provided for that resource in the collection. This provides the full set of lifecycle links for that resource based on its most up-to-date state.

Request debugging

The request ID is always present in every API response and can be used for debugging. You can use this value to correlate events from the System Log events.

The following header is set in each response:

X-Okta-Request-Id - The unique identifier for the API request

HTTP/1.1 200 OK
X-Okta-Request-Id: reqVy8wsvmBQN27h4soUE3ZEnA

Cross-Origin Resource Sharing (CORS)

Cross-Origin Resource Sharing (CORS) is a mechanism that allows a web page to make an AJAX call by using XMLHttpRequest (XHR) to a domain that is different from the one where the script was loaded. Such cross-domain requests would otherwise be forbidden by web browsers, in accordance with the same origin security policy. CORS defines a standardized way in which the browser and the server can interact to determine whether to allow the cross-origin request.

In Okta, CORS allows JavaScript, which is hosted on your websites, to make an XHR to the Okta API with a token. See OpenID Connect & OAuth 2.0.

Every website origin must be explicitly permitted through the Admin Console for CORS. See Enabling CORS for more information on how to allow your website to make cross-origin requests.

Caution: Only grant access to specific origins (websites) that you control and trust to access the Okta API.

API support

The Okta API supports CORS on an API by API basis. If you're building an application that needs CORS, check that the specific operation supports CORS for your use case. APIs that support CORS are marked with the following icon: .
