Authenticate a User given a method_id (the associated email_id or phone_id) and a code. This endpoint verifies that the code is valid, hasn’t expired or been previously used, and any optional security settings such as IP match or user agent match are satisfied. A given method_id may only have a single active OTP code at any given time, if a User requests another OTP code before the first one has expired, the first one will be invalidated.

Authorizations

​
Authorization
string
header
required

Basic authentication header of the form Basic <encoded-value>, where <encoded-value> is the base64-encoded string username:password.

Body

application/json

Request type

​
method_id
string
required

The email_id or phone_id involved in the given authentication.

​
code
string
required

The code to authenticate.

​
attributes
object

Provided attributes to help with fraud detection. These values are pulled and passed into Stytch endpoints by your application.

​
options
object

Specify optional security settings.

​
session_token
string

The session_token associated with a User's existing Session.

​
session_duration_minutes
integer<int32>

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.

​
session_jwt
string

The session_jwt associated with a User's existing Session.

​
session_custom_claims
object

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.

​
telemetry_id
string

If the telemetry_id is passed, as part of this request, Stytch will call the Fingerprint Lookup API and store the associated fingerprints and IPGEO information for the User. Your workspace must be enabled for Device Fingerprinting to use this feature.

Response

Successful response

​
request_id
string
required

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.

​
user_id
string
required

The unique ID of the affected User.

​
method_id
string
required

The email_id or phone_id involved in the given authentication.

​
session_token
string
required

A secret token for a given Stytch Session.

​
session_jwt
string
required

The JSON Web Token (JWT) for a given Stytch Session.

​
user
object
required

The user object affected by this API call. See the Get user endpoint for complete response field details.

​
reset_sessions
boolean
required

Indicates if all other of the User's Sessions need to be reset. You should check this field if you aren't using Stytch's Session product. If you are using Stytch's Session product, we revoke the User's other sessions for you.

​
status_code
integer<int32>
required

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.

​
session
object

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 Session object for complete response fields.

​
user_device
object

If a valid telemetry_id was passed in the request and the Fingerprint Lookup API returned results, the user_device response field will contain information about the user's device attributes.
