About

The Okta registration inline hook allows you to integrate your own custom code into Okta's Profile Enrollment (opens new window) flow. The hook is triggered after Okta receives the registration or profile update request. Your custom code can:

  • Allow or deny the registration attempt, based on your own validation of the information the user has submitted
  • Set or override the values that are populated in attributes of the user's Okta profile

Note: Profile Enrollment and self-service registration (SSR) inline hooks only work with the Okta Sign-In Widget version 4.5 or later.

Objects in the Request from Okta

The outbound call from Okta to your external service includes the following objects in its JSON payload:

requestType

OTP request or event for which this transaction is being requested: self-service registration (SSR) or Progressive Enrollment.

Values for requestType are one of the following:

Enum Value Associated Okta Event
self.service.registration self-service registration (SSR)
progressive.profile Progressive Enrollment

data.userProfile

This object appears in SSR requests from Okta. The object contains name-value pairs for each registration related attribute supplied by the user in the Profile Enrollment form, including:

  • lastName
  • firstName
  • login
  • email
  • other custom attributes on the Sign-In Widget

The following attributes aren't included in the data.userProfile object:

  • the password field
  • any fields corresponding to user profile attributes marked as sensitive in your Okta user schema

Using the com.okta.user.profile.update commands you send in your response, you can modify the values of the attributes, or add other attributes, before the values are assigned to the Okta user profile that will be created for the registering user.

You can only set values for profile fields which already exist in your Okta user profile schema. Registration inline hook functionality can only set values. It can't create new fields.

data.UserProfileUpdate

Identity Engine

This object appears in Progressive Profile requests from Okta. The object contains the delta between existing name-value pairs and the attributes that your end user wants to update.

Use the com.okta.user.progressive.profile.update command in your response to progressively change the values of delta attributes in the user's Okta profile.

Note: You can also allow end users to update non-sensitive attributes in addition to the delta attributes Okta sends in the request.

data.action

Note: The data.action object can appear in both SSR and Progressive Profile requests.

The action that Okta is currently set to take, regarding whether to allow this registration attempt.

There are two possible values:

  • ALLOW indicates that the registration attempt will be allowed to proceed
  • DENY indicates that the registration attempt will be terminated (no user will be created in Okta)

The action is ALLOW by default (in practice, DENY will never be sent to your external service).

Using the com.okta.action.update command in your response, you can change the action that Okta will take.

Response objects that you send

The objects that you can return in the JSON payload of your response are an array of one or more commands, to be executed by Okta, or an error object, to indicate problems with the registration request.

Note: The size of your response payload must be less than 256 KB.

The response objects are defined as follows:

commands

The commands object lets you invoke commands to modify or add values to the attributes in the Okta user profile that will be created for this user, as well as to control whether or not the registration attempt is allowed to proceed.

This object is an array, allowing you to send multiple commands in your response. Each array element requires a type property and a value property. The type property is where you specify which of the supported commands you wish to execute, and value is where you supply parameters for that command.

Property Description Data Type
type One of the supported commands. String
value Operand to pass to the command. value

For example commands, see the value section below.

Supported commands

The following commands are supported for the registration inline hook type:

Command Description
com.okta.user.profile.update Change attribute values in the user's Okta user profile. For SSR only. Invalid if used with a Progressive Profile response.
com.okta.action.update Allow or deny the user's registration.
com.okta.user.progressive.profile.update Change attribute values in the user's Okta Progressive Profile. Identity Engine

To set attributes in the user's Okta profile, supply a type property set to com.okta.user.profile.update, together with a value property set to a list of key-value pairs corresponding to the Okta user profile attributes you want to set. The attributes must already exist in your user profile schema.

To explicitly allow or deny registration to the user, supply a type property set to com.okta.action.update, together with a value property set to {"registration": "ALLOW"} or {"registration": "DENY"}. The default is to allow registration.

In Okta Identity Engine, to set attributes in the user's profile, supply a type property set to com.okta.user.progressive.profile.update, together with a value property set to a list of key-value pairs corresponding to the Progressive Enrollment attributes that you want to set. See Registration inline hook - Send response. Identity Engine

Commands are applied in the order that they appear in the array. Within a single com.okta.user.profile.update or com.okta.user.progressive.profile.update command, attributes are updated in the order that they appear in the value object.

You can never use a command to update the user's password, but you are allowed to set the values of attributes other than password that are designated sensitive in your Okta user schema. However, the values of those sensitive attributes, if included as fields in the Profile Enrollment form, aren't included in the data.userProfile object sent to your external service by Okta. See data.userProfile.

value

The value object is the parameter to pass to the command.

For com.okta.user.profile.update commands, value should be an object containing one or more name-value pairs for the attributes you wish to update, for example:

{
   "commands":[
      {
         "type":"com.okta.user.profile.update",
         "value":{
            "middleName":"Danger",
            "customerId":12345
         }
      }
   ]
}

The above example assumes that there is an attribute customerId defined in your Okta user schema (middleName is defined by default).

The same result could also be accomplished by means of two separate com.okta.user.profile.update commands, as follows:

{
   "commands":[
      {
         "type":"com.okta.user.profile.update",
         "value":{
            "middleName":"Danger"
         }
      },
      {
         "type":"com.okta.user.profile.update",
         "value":{
            "customerId":12345
         }
      }
   ]
}

For com.okta.action.update commands, value should be an object containing the attribute action set to a value of either ALLOW or DENY, indicating whether the registration should be permitted or not, for example:

{
  "commands": [
    {
      "type": "com.okta.action.update",
      "value": {
        "registration": "DENY"
      }
    }
  ]
}

Registrations are allowed by default, so setting a value of ALLOW for the action field is valid but superfluous.

error

See error for general information about the structure to use for the error object.

For the registration inline hook, the error object provides a way of displaying an error message to the end user who is trying to register or update their profile.

Note: Generic Progressive Enrollment error messages are only available in the Identity Engine.

  • If you're using the Okta Sign-In Widget for Profile Enrollment, only the errorSummary messages of the errorCauses objects that your external service returns appear as inline errors, given the following:

    • You don't customize the error handling behavior of the widget.
    • The location of errorSummary in the errorCauses object specifies the request object's user profile attribute.
  • If you don't return a value for the errorCauses object, and deny the user's registration attempt through the commands object in your response to Okta, one of the following generic messages appears to the end user:

    • "Registration cannot be completed at this time." (SSR)
    • "We found some errors. Please review the form and make corrections." (Progressive Enrollment)
  • If you don't return an error object at all and the registration is denied, the following generic message appears to the end user:

    • "Registration denied." (SSR)
    • "Profile update denied." (Progressive Enrollment)

Note: If you include an error object in your response, no commands are executed and the registration fails. This holds true even if the top-level errorSummary and the errorCauses objects are omitted.

Timeout behavior

If there is a response timeout after receiving the Okta request, the Okta process flow stops. Depending on the request, either the self-service registration or the profile update is denied. One of the following default UI messages appears:

  • "There was an error creating your account. Please try registering again." (SSR)
  • "Your profile couldn't be updated at this time. Please try again later." (Profile Enrollment)

Sample SSR request

The following is an example of a JSON request received from Okta. The request properties contain data submitted by the end user who is trying to self register.

See request properties for full details.

                "url": {
                    "value": "/idp/idx/enroll/new"
                }
            }
        },
        "userProfile": {
            "firstName": "Rosario",
            "lastName": "Jones",
            "login": "rosario.jones@example.com",
            "email": "rosario.jones@example.com"
        },
        "action": "ALLOW"
    }
}

Sample SSR responses

The external service responds to Okta indicating whether to accept the end user's self-registration attempt. If self-registration is allowed, an update to a user profile attribute can also be returned. The commands object in the body of the HTTPS response contains specific syntax that configures these operations.

See response properties for full details.

Sample SSR response to update a user profile

The following sample response shows a successful self-registration attribute update using com.okta.user.profile.update:

{
    "commands": [
        {
            "type": "com.okta.user.profile.update",
            "value": {
                "login": "first.last@example.com"
            }
        }
    ]
}

Sample SSR response to deny a user registration

The following sample response uses the DENY value and a custom error caused by an invalid email domain:

{
    "commands": [
        {
            "type": "com.okta.action.update",
            "value": {
                "registration": "DENY"
            }
        }
    ],
    "error": {
        "errorSummary": "Incorrect email address. Please contact your admin.",
        "errorCauses": [
            {
                "errorSummary": "Only example.com emails can register.",
                "reason": "INVALID_EMAIL_DOMAIN",
                "locationType": "body",
                "location": "data.userProfile.email",
                "domain": "end-user"
            }
        ]
    }
}

        "userProfileUpdate": {
            "employeeNumber": "1234"
        }
    }
}

Sample progressive enrollment responses

The external service responds to Okta indicating whether to accept the end user's profile update. The response returns a commands object in the body of the HTTPS response. This object contains specific syntax that indicates whether the user is allowed or denied to update their profile with Okta.

See response properties for full details.

Sample progressive enrollment response to update a user profile

The following sample response shows the addition of an employee number to an end user's profile:

{
    "commands": [
        {
            "type": "com.okta.user.progressive.profile.update",
            "value": {
                "employeeNumber": "1234"
            }
        }
    ]
}

Sample progressive enrollment response to deny a user registration

The following sample response uses the DENY value and a custom error caused by an invalid employee number:

{
    "commands": [
        {
            "type": "com.okta.action.update",
            "value": {
                "registration": "DENY"
            }
        }
    ],
    "error": {
        "errorSummary": "Incorrect employee number. Enter an employee number with 4 digits.",
        "errorCauses": [
            {
                "errorSummary": "Only employee numbers with 4 digits can register.",
                "reason": "INVALID_EMPLOYEE_NUMBER",
                "locationType": "body",
                "location": "data.userProfile.employeeNumber",
                "domain": "end-user"
            }
        ]
    }
}
