Authenticate a via an Email Magic Link token. If the Member’s status is pending or invited, they will be updated to active. If the Email Magic Link is expired or previously used, the endpoint will return an error. Provide the session_duration_minutes parameter to set the lifetime of the session. If the session_duration_minutes parameter is not specified, a Stytch session will be created with a 60 minute duration.

​
Multi-factor authentication (MFA)

If the Member is required to complete MFA to log in to the Organization, the returned value of member_authenticated will be false and an intermediate_session_token will be returned. The intermediate_session_token can be passed into the following endpoints to complete the MFA step and acquire a full member session (the session_duration_minutes and session_custom_claims parameters will be ignored): The intermediate_session_token can also be used with the Exchange Intermediate Session endpoint or the Create Organization via Discovery endpoint to join a different Organization or create a new one. The session_duration_minutes and session_custom_claims parameters will be ignored. If a valid session_token or session_jwt is passed in, the Member will not be required to complete an MFA step.

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

​
magic_links_token
string
required

The Email Magic Link token to authenticate.

​
pkce_code_verifier
string

A base64url encoded one time secret used to validate that the request starts and ends on the same device.

​
session_token
string

Reuse an existing session instead of creating a new one. If you provide a session_token, Stytch will update the session. If the session_token and magic_links_token belong to different Members, the session_token will be ignored. This endpoint will error if both session_token and session_jwt are provided.

​
session_jwt
string

Reuse an existing session instead of creating a new one. If you provide a session_jwt, Stytch will update the session. If the session_jwt and magic_links_token belong to different Members, the session_jwt will be ignored. This endpoint will error if both session_token and session_jwt are provided.

​
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 be created with a 60 minute duration. If you don't want to use the Stytch session product, you can ignore the session fields in the response.

​
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.

locale
enum<string>

If the Member needs to complete an MFA step, and the Member has a phone number, this endpoint will pre-emptively send a one-time passcode (OTP) to the Member's phone number. The locale argument will be used to determine which language to use when sending the passcode.

Parameter is an IETF BCP 47 language tag, e.g. "en".

Currently supported languages are English ("en"), Spanish ("es"), and Brazilian Portuguese ("pt-br"); if no value is provided, the copy defaults to English.

Available options:

​
intermediate_session_token
string

Adds this primary authentication factor to the intermediate session token. If the resulting set of factors satisfies the organization's primary authentication requirements and MFA requirements, the intermediate session token will be consumed and converted to a member session. If not, the same intermediate session token will be returned.

​
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 Member. Your workspace must be enabled for Device Fingerprinting to use this feature.

The returned Intermediate Session Token contains an Email Magic Link factor associated with the Member's email address.

The token has a default expiry of 10 minutes. It can also be used with the Exchange Intermediate Session endpoint to join a specific Organization that allows the factors represented by the intermediate session token; or the Create Organization via Discovery endpoint to create a new Organization and Member.
