Expressions allow you to reference, transform, and combine attributes before you store them on a User Profile or before passing them to an application for authentication or provisioning. For example, you might use a custom expression to create a username by stripping @company.com from an email address. Or, you might combine the firstName and lastName attributes into a single displayName attribute.

This document details the features and syntax of the Okta Expression Language, which you can use throughout the Okta Admin Console and API. Okta updates this document over time as new capabilities are added to the language. The Okta Expression Language is based on SpEL (opens new window) and uses a subset of functionalities offered by SpEL.

Referencing user attributes

When you create an Okta expression, you can reference any attribute that lives on an Okta User Profile or Application User Profile.

Okta User Profile

Every user has an Okta User Profile. The Okta User Profile is the central source of truth for the core attributes of a User. To reference an Okta User Profile attribute, just reference user and specify the attribute variable name.

Syntax Definitions examples
user.$attribute user reference to the Okta User
$attribute the attribute variable name

Application User Profile

In addition to an Okta User Profile, all Users have a separate Application User Profile for each of their applications. Application User Profiles store application-specific information about Users, such as the application userName or user role. To reference an Application User Profile attribute, specify the application variable and the attribute variable in the user profile of the application. In specifying the application, you can either name the specific application you're referencing or use an implicit reference to an in-context application.

Syntax Definitions examples
$appuser.$attribute $appuser explicit reference to specific app
$attribute the attribute variable name
appuser.$attribute appuser implicit reference to in-context app
$attribute the attribute variable name

Note: Explicit references to apps aren't supported for OAuth 2.0/OIDC custom claims. See Expressions for OAuth 2.0/OIDC custom claims.

Note: The application reference is usually the name of the application, as distinct from the label (display name). See Application properties. If your organization configures multiple instances of the same application, the names of the later instances are differentiated by a randomly assigned suffix, for example: zendesk_9ao1g13. You can find the name of any specific app instance in the Profile Editor, where it appears in lighter text beneath the label of the app.

IdP User Profile

In addition to an Okta User Profile, some users have separate IdP User Profiles for their external Identity Provider. These IdP User Profiles are used to store IdP-specific information about a user. You can use this data in an EL expression to transform an external user's username into the equivalent Okta username. To reference an IdP User Profile attribute, specify the IdP variable and the corresponding attribute variable for the IdP User Profile of that identity provider. This profile is only available when specifying the username transform used to generate an Okta username for the IdP user.

Syntax Definitions Examples
idpuser.$attribute idpuser implicit reference to in-context IdP
$attribute the attribute variable name

In Universal Directory, the base Okta User Profile has about 30 attributes. You can add any number of custom attributes. All Application User Profiles have a username attribute and possibly others depending on the application. To find a full list of Okta User and App User attributes and their variable names, in the Okta Admin Console go to People > Profile Editor. If you're not using Universal Directory, contact your Support or Professional Services team.

Referencing Application and Organization properties

In addition to referencing user attributes, you can also reference Application properties and the properties of your Organization. To reference a particular attribute, just specify the appropriate binding and the attribute variable name. The binding for an Application is its name with _app appended. The App name can be found as described in Application user profile attributes. Here are some examples:

Application properties

Syntax Definitions examples
$app.$attribute $app explicit reference to specific app instance
$attribute the attribute variable name
app.$attribute app implicit reference to in-context app instance
$attribute the attribute variable name

Note: Explicit references to apps aren't supported for custom OAuth 2.0/OIDC claims.

Organization properties

Syntax Definitions Examples
org.$attribute org reference to Okta org
$attribute the attribute variable name

Referencing Session properties

In addition to referencing User, App, and Organization properties, you can also reference User Session properties. Session properties allow you to configure Okta to pass Dynamic Authentication Context to SAML apps through the assertion using custom SAML attributes. The App can then use that information to limit access to certain App-specific behaviors and calculate the risk profile for the signed-in user.

Session properties

Syntax Definitions Evaluation example
session.amr session reference to a user's session
amr the attribute name that is resolvable to an array of Authentication Method References (opens new window)
["pwd"] — password used by the user for authentication
["mfa", "pwd", "kba"] — password and MFA security question used by the user for authentication
["mfa", "mca", "pwd", "sms"] — password and MFA SMS used by the user for authentication


Okta offers a variety of functions to manipulate attributes or properties to generate a desired output. You can combine and nest functions inside a single expression.

Double val = 123.6 124
Convert.toNum(string) Double Convert.toNum(val) String val = '3.141' 3.141

Note: Convert.toInt(double) rounds the passed numeric value either up or down to the nearest integer. Be sure to consider integer type range limitations when converting from a number to an integer with this function.

Country code conversion functions

These functions convert between ISO 3166-1 2-character country codes (Alpha 2), 3-character country codes (Alpha 3), numeric country codes, and full ISO country names.

Function Return type Example Output
Iso3166Convert.toAlpha2(string) String Iso3166Convert.toAlpha2("IND") IN

Iso3166Convert.toNumeric(string) String Iso3166Convert.toNumeric("USA") 840
Iso3166Convert.toName(string) String Iso3166Convert.toName("IN") India

Note: All these functions take ISO 3166-1 2-character country codes (Alpha 2), 3-character country codes (Alpha 3), and numeric country codes as input. The function determines the input type and returns the output in the format specified by the function name.

For more information on these codes, see the ISO 3166-1 online lookup tool (opens new window).

Group functions

Group functions return either an array of groups or True or False.

Function Return type Example
getFilteredGroups Array getFilteredGroups({"00gml2xHE3RYRx7cM0g3"}, "group.name", 40)
Groups.contains Array contains(app_type/app_instance_id, pattern, limit)
Groups.startsWith Array startsWith(app_type/app_instance_id, pattern, limit)
Groups.endsWith Array endsWith(app_type/app_instance_id, pattern, limit)
isMemberOfGroupName Boolean isMemberOfGroupName("group1")
isMemberOfGroup Boolean isMemberOfGroup("groupId")
isMemberOfAnyGroup Boolean isMemberOfAnyGroup("groupId1", "groupId2", "groupId3")
isMemberOfGroupNameStartsWith Boolean isMemberOfGroupNameStartsWith("San Fr")
isMemberOfGroupNameContains Boolean isMemberOfGroupNameContains("admin")
isMemberOfGroupNameRegex Boolean isMemberOfGroupNameRegex("/.*admin.*")

Note: The Groups.contains, Groups.startsWith, and Groups.endsWith group functions are designed to work only with group claims. You can't use these functions with property mappings.

For an example using group functions and for more information on using group functions for dynamic and static allow lists, see Customize tokens returned from Okta.

Important: When you use Groups.startWith, Groups.endsWith, or Groups.contains, the pattern argument is matched and populated on the name attribute rather than the Group's email (for example, when using Google Workspace). If you are targeting groups that may have duplicate group names (such as Google Groups), use the getFilteredGroups Group function instead.

Example: getFilteredGroups({"00gml2xHE3RYRx7cM0g3"}, "group.name", 40) )

See the Parameter examples section of Use group functions for static group allow lists for more information on the parameters used in this Group function.

Linked object function

Use this function to retrieve the user identified with the specified primary relationship. You can then access properties of that user.

  • Function: user.getLinkedObject($primaryName)
    • Parameter: (String primaryName)
    • Return Type: User
    • Example: user.getLinkedObject("manager").lastName
    • Example Result: Gates

Time functions

Function Input parameter signature Return type Example output
Time.now (String timeZoneId, String format) String Time.now() 2015-07-31T17:18:37.979Z (Current time, UTC format)
Time.now("EST") 2015-07-31T13:30:49.964-04:00 (Specified time zone)
Time.now("EST", "YYYY-MM-dd HH:mm:ss") 2015-07-31 13:36:48 (Specified time zone and format, military time)
Time.fromWindowsToIso8601 (String time) String Windows timestamp time as a string (Windows/LDAP timestamp doc) The passed-in time expressed in ISO 8601 format (specifically the RFC 3339 subset of the ISO standard).
Time.fromUnixToIso8601 (String time) String Unix timestamp time as a string (Unix timestamp reference) The passed-in time expressed in ISO 8601 format (specifically the RFC 3339 subset of the ISO standard).
Time.fromStringToIso8601 (String time, String format) String Timestamp time in a human-readable yet machine-parseable arbitrary format format (as defined by Joda time pattern (opens new window)) The passed-in time expressed in ISO 8601 format (specifically the RFC 3339 subset of the ISO standard).
Time.fromIso8601ToWindows (String time) String ISO 8601 timestamp time as a string The passed-in time expressed in Windows timestamp format.
Time.fromIso8601ToUnix (String time) String ISO 8601 timestamp time as a string The passed-in time expressed in Unix timestamp format.
Time.fromIso8601ToString (String time, String format) String ISO 8601 timestamp time, to convert to format using the same Joda time pattern (opens new window) semantics as fromStringToIso8601 The passed-in time expressed informat format.

Note: Both input parameters are optional for the Time.now function. The time zone ID supports both new and old style formats, listed below. The third example for the Time.now function shows how to specify the military time format.

Okta supports the use of the time zone IDs and aliases listed in the Time Zone Codes table.

Manager/assistant functions

Function Description Example
getManagerUser(managerSource).$attribute Gets the manager's Okta user attribute values getManagerUser("active_directory").firstName
getManagerAppUser(managerSource, attributeSource).$attribute Gets the manager's app user attribute values for the app user of any appinstance. getManagerAppUser("active_directory", "google").firstName
getAssistantUser(assistantSource).$attribute Gets the assistant's Okta user attribute values. getAssistantUser("active_directory").firstName
getAssistantAppUser(assistantSource, attributeSource).$attribute Gets the assistant's app user attribute values for the app user of any appinstance. getAssistantAppUser("active_directory", "google").firstName

The following should be noted about these functions:

  • Be sure to pass the correct App name for the managerSource, assistantSource, and attributeSource parameters.
  • At this time, active_directory is the only supported value for managerSource and assistantSource.
  • Calling the getManagerUser("active_directory") function doesn't trigger a user profile update after the manager is changed.

Directory and Workday functions

Function Description
hasDirectoryUser() Checks whether the user has an Active Directory assignment and returns a boolean
hasWorkdayUser() Checks whether the user has a Workday assignment and returns a boolean
findDirectoryUser() Finds the Active Directory App user object and returns that object or null if the user has more than one or no Active Directory assignments
findWorkdayUser() Finds the Workday App user object and returns that object or null if the user has more than one or no Active Directory assignments

The functions above are often used in tandem to check whether a user has an AD or Workday assignment, and if so, return an AD or Workday attribute. See the 'Popular Expressions' table below for some examples.

Constants and operators

Common Actions Example
Refer to a String constant 'Hello world'
Refer to an Integer constant 1234
Refer to a Number constant 3.141
Refer to a Boolean constant true
Refer to an Array element {1, 2, 3}[0] or user.arrayProperty[0]
Concatenate two strings user.firstName + user.lastName
Concatenate two strings with space user.firstName + " " + user.lastName
Ternary operator example:
If group code is 123, assign value of Sales, else assign Other
user.groupCode == 123 ? 'Sales' : 'Other'

Conditional expressions

You can specify IF...THEN...ELSE statements with the Okta EL. The primary use of these expressions is profile mappings and group rules. Group rules do not usually specify an ELSE component.

The format for conditional expressions is

[Condition] ? [Value if TRUE] : [Value if FALSE]

There are several rules for specifying the condition.

  • Expressions must have valid syntax.
  • Expressions must evaluate to Boolean.
  • Expressions cannot contain an assignment operator, such as =.
  • User attributes used in expressions can contain only available User or AppUser attributes.

The following functions are supported in conditions.

  • Any Okta Expression Language function
  • The AND operator
  • The OR operator
  • The ! operator to designate NOT
  • Standard relational operators including <, >, <=, and >=.
  • The matches operator to evaluate a String against a regular expression.

Note: Use the double equals sign == to check for equality and != for inequality.

The following functions are not supported in conditions:

  • Convert
  • Array
  • Time


For these samples, assume that user has following attributes in Okta.

Attribute Type
firstName String
lastName String
middleInitial String
fullName String
honorificPrefix String
email1 String
email2 String
additionalEmail Boolean
city String
salary Int
isContractor Boolean
Samples using profile mapping

The following samples are valid conditional expressions that apply to profile mapping. The attribute courtesyTitle is from another system being mapped to Okta.

If the middle initial is not empty, include it as part of the full name, using just the first character and appending a period.
firstName + " " + (String.len(middleInitial) == 0 ? "" : (String.substring(middleInitial, 0, 1) + ". ")) + lastName

Include the honorific prefix in front of the full name, or use the courtesy title instead if it exists. If both are absent, don't use any title.
(courtesyTitle != "" ? (courtesyTitle + " ") : honorificPrefix != "" ? (honorificPrefix + " ") : "") + firstName + " " + (String.len(middleInitial) == 0 ? "" : (String.substring(middleInitial, 0, 1) + ". ")) + lastName

Samples using group rules

The following samples are valid conditional expressions. The actions in these cases are group assignments.

IF (Implicit) Condition Assign to this Group Name if Condition is TRUE
IF String.stringContains(user.firstName, "dummy") dummyUsers
IF user.city == "San Francisco" sfo
IF user.salary >= 1000000 expensiveEmployee
IF !user.isContractor fullTimeEmployees
IF user.salary > 1000000 AND !user.isContractor expensiveFullTimeEmployees
Samples checking for null and blank attributes

To catch User attributes that are null or blank, use the following valid conditional expression:
user.employeeNumber != "" AND user.employeeNumber != null ? user.employeeNumber : user.nonEmployeeNumber

If a Profile attribute has never been populated, catch it with the following expression:
user.employeeNumber != null

If a Profile attribute was populated in the past but the content is removed, it's no longer null but an empty string. To catch these empty strings, use the following expression:
user.employeeNumber != ""

Sample user data:

  • Firstname = Winston
  • Lastname = Churchill
  • Email = winston.churchill@gmail.com
  • Login = winston.churchill@gmail.com
Value to obtain Expression Example output Explanation
Firstname user.firstName Winston Obtain the value of users' firstname attribute.
Firstname + Lastname user.firstName + user.lastName WinstonChurchill Obtain Firstname and Lastname values and append each together.
Firstname + Lastname with Separator user.firstName + "." + user.lastName Winston.Churchill Obtain Firstname value, append a "." character. Obtain and append the Lastname value.

From result, retrieve 1 character starting at the beginning of the string. Obtain Lastname value. From result, retrieve characters greater than position 0 thru position 6, including position 6.
Lower Case First Initial + Lower Case Lastname with Separator toLowerCase(substring( user.firstName, 0, 1)) + "." + toLowerCase(user.lastName) w.churchhill Obtain Firstname value. From result, retrieve characters greater than position 0 thru position 1, including position 1. Convert result to lowercase. Append a "." character. Obtain the Lastname value. Convert to lowercase and append.

From result, parse everything after the "@ character". From result, parse everything before the "." character. Convert to uppercase. Append a backslash "" character. Obtain the email value again. From result, parse for everything before the "@" character.
Email Domain + Lowercase First Initial and Lastname with Separator toUpperCase(substringBefore( substringAfter(user.email, "@"), ".")) + "\" + toLowerCase(substring( user.firstName, 0, 1)) + toLowerCase(user.lastName) GMAIL\wchurchill Obtain Email value. From the result, parse everything after the "@ character". From result, parse everything before the "." character. Convert to uppercase. Append a backslash "" character. Obtain the Firstname value. From the result, retrieve characters greater than position 0 thru position 1, including position 1. Convert it to lowercase. Obtain the Lastname value and convert it to lowercase.

Active Directory UPN hasDirectoryUser() ? findDirectoryUser().managerUpn : null bob@okta.com Check if user has an Active Directory assignment, and if so, return their Active Directory manager UPN.

Expressions for OAuth 2.0/OIDC custom claims

Okta provides a few expressions that you can only use with OAuth 2.0/OIDC custom claims.

Syntax Definitions Examples
app.$attribute app refers to the name of the OIDC app.
$attribute refers to the attribute variable name.
access.scope access refers to the access token that requests the scopes.
scope refers to the array of granted scopes.


Sample using app attributes

To include an app Profile label, use the following expression:

See Include app-specific information in a custom claim.

Sample using access.scope

In API Access Management custom authorization servers, you can name a claim scope. Then, you can use the expression access.scope to return an array of granted scope strings.

To include a granted scope array and convert it to a space-delimited string, use the following expression:
String.replace(Arrays.toCsvString(access.scope),","," ")

Appendix: Time zone codes
