Instance Method Details

#authenticate(public_key_credential:, session_token: nil, session_duration_minutes: nil, session_jwt: nil, session_custom_claims: nil) ⇒ Object

Complete the authentication of a Passkey or WebAuthn registration by passing the response from the [navigator.credentials.get()](www.w3.org/TR/webauthn-2/#sctn-getAssertion) request to the authenticate endpoint.

If the [webauthn-json](github.com/github/webauthn-json) library’s ‘get()` method was used, the response can be passed directly to the [authenticate endpoint](stytch.com/docs/api/webauthn-authenticate). If not some fields from the [navigator.credentials.get()](www.w3.org/TR/webauthn-2/#sctn-getAssertion) response will need to be converted from array buffers to strings and marshalled into JSON.

Parameters:

public_key_credential

The response of the [navigator.credentials.create()](www.w3.org/TR/webauthn-2/#sctn-createCredential). The type of this field is String.

session_token

The ‘session_token` associated with a User’s existing Session. The type of this field is nilable String.

session_duration_minutes

Set the session lifetime to be this many minutes from now. This will start a new session if one doesn’t already exist, returning both an opaque ‘session_token` and `session_jwt` for this session. Remember that the `session_jwt` will have a fixed lifetime of five minutes regardless of the underlying session duration, and will need to be refreshed over time.

This value must be a minimum of 5 and a maximum of 527040 minutes (366 days).

If a ‘session_token` or `session_jwt` is provided then a successful authentication will continue to extend the session this many minutes.

If the ‘session_duration_minutes` parameter is not specified, a Stytch session will not be created. The type of this field is nilable Integer.

session_jwt

The ‘session_jwt` associated with a User’s existing Session. The type of this field is nilable String.

session_custom_claims

Add a custom claims map to the Session being authenticated. Claims are only created if a Session is initialized by providing a value in ‘session_duration_minutes`. Claims will be included on the Session object and in the JWT. To update a key in an existing Session, supply a new value. To delete a key, supply a null value.

Custom claims made with reserved claims (“iss”, “sub”, “aud”, “exp”, “nbf”, “iat”, “jti”) will be ignored. Total custom claims size cannot exceed four kilobytes. The type of this field is nilable object.

Returns:

An object with the following fields:

request_id

Globally unique UUID that is returned with every API call. This value is important to log for debugging purposes; we may ask for this value to help identify a specific API call when helping you debug an issue. The type of this field is String.

user_id

The unique ID of the affected User. The type of this field is String.

webauthn_registration_id

The unique ID for the Passkey or WebAuthn registration. The type of this field is String.

session_token

A secret token for a given Stytch Session. The type of this field is String.

session_jwt

The JSON Web Token (JWT) for a given Stytch Session. The type of this field is String.

user

The ‘user` object affected by this API call. See the [Get user endpoint](stytch.com/docs/api/get-user) for complete response field details. The type of this field is User (object).

status_code

The HTTP status code of the response. Stytch follows standard HTTP response status code patterns, e.g. 2XX values equate to success, 3XX values are redirects, 4XX are client errors, and 5XX are server errors. The type of this field is Integer.

session

If you initiate a Session, by including ‘session_duration_minutes` in your authenticate call, you’ll receive a full Session object in the response.

See [GET sessions](stytch.com/docs/api/session-get) for complete response fields.

The type of this field is nilable Session (object).

#authenticate_start(domain:, user_id: nil, return_passkey_credential_options: nil) ⇒ Object

Initiate the authentication of a Passkey or WebAuthn registration.

To optimize for Passkeys, set the ‘return_passkey_credential_options` field to `true`.

After calling this endpoint, the browser will need to call [navigator.credentials.get()](www.w3.org/TR/webauthn-2/#sctn-getAssertion) with the data from ‘public_key_credential_request_options` passed to the [navigator.credentials.get()](www.w3.org/TR/webauthn-2/#sctn-getAssertion) request via the public key argument. We recommend using the `get()` wrapper provided by the webauthn-json library.

If you are not using the [webauthn-json](github.com/github/webauthn-json) library, ‘the public_key_credential_request_options` will need to be converted to a suitable public key by unmarshalling the JSON and converting some the fields to array buffers.

Parameters:

domain

The domain for Passkeys or WebAuthn. Defaults to ‘window.location.hostname`. The type of this field is String.

user_id

The ‘user_id` of an active user the Passkey or WebAuthn registration should be tied to. The type of this field is nilable String.

return_passkey_credential_options

If true, the ‘public_key_credential_creation_options` returned will be optimized for Passkeys with `userVerification` set to `“preferred”`.

The type of this field is nilable Boolean.

Returns:

An object with the following fields:

request_id

Globally unique UUID that is returned with every API call. This value is important to log for debugging purposes; we may ask for this value to help identify a specific API call when helping you debug an issue. The type of this field is String.

user_id

The unique ID of the affected User. The type of this field is String.

public_key_credential_request_options

Options used for Passkey or WebAuthn authentication. The type of this field is String.

status_code

The HTTP status code of the response. Stytch follows standard HTTP response status code patterns, e.g. 2XX values equate to success, 3XX values are redirects, 4XX are client errors, and 5XX are server errors. The type of this field is Integer.

#register_start(user_id:, domain:, user_agent: nil, authenticator_type: nil, return_passkey_credential_options: nil) ⇒ Object

Initiate the process of creating a new Passkey or WebAuthn registration.

To optimize for Passkeys, set the ‘return_passkey_credential_options` field to `true`.

After calling this endpoint, the browser will need to call [navigator.credentials.create()](www.w3.org/TR/webauthn-2/#sctn-createCredential) with the data from [public_key_credential_creation_options](w3c.github.io/webauthn/#dictionary-makecredentialoptions) passed to the [navigator.credentials.create()](www.w3.org/TR/webauthn-2/#sctn-createCredential) request via the public key argument. We recommend using the ‘create()` wrapper provided by the webauthn-json library.

If you are not using the [webauthn-json](github.com/github/webauthn-json) library, the ‘public_key_credential_creation_options` will need to be converted to a suitable public key by unmarshalling the JSON, base64 decoding the user ID field, and converting user ID and the challenge fields into an array buffer.

Parameters:

user_id

The ‘user_id` of an active user the Passkey or WebAuthn registration should be tied to. The type of this field is String.

domain

The domain for Passkeys or WebAuthn. Defaults to ‘window.location.hostname`. The type of this field is String.

user_agent

The user agent of the User. The type of this field is nilable String.

authenticator_type

The requested authenticator type of the Passkey or WebAuthn device. The two valid values are platform and cross-platform. If no value passed, we assume both values are allowed. The type of this field is nilable String.

return_passkey_credential_options

If true, the ‘public_key_credential_creation_options` returned will be optimized for Passkeys with `residentKey` set to `“required”` and `userVerification` set to `“preferred”`.

The type of this field is nilable Boolean.

Returns:

An object with the following fields:

request_id

Globally unique UUID that is returned with every API call. This value is important to log for debugging purposes; we may ask for this value to help identify a specific API call when helping you debug an issue. The type of this field is String.

user_id

The unique ID of the affected User. The type of this field is String.

public_key_credential_creation_options

Options used for Passkey or WebAuthn registration. The type of this field is String.

status_code

The HTTP status code of the response. Stytch follows standard HTTP response status code patterns, e.g. 2XX values equate to success, 3XX values are redirects, 4XX are client errors, and 5XX are server errors. The type of this field is Integer.
