Authenticate Magic Link

Authenticate Magic Link

POSThttps://test.stytch.com/v1/b2b/magic_links/authenticate

Authenticate a Member with a Magic Link. This endpoint requires a Magic Link token that is not expired or previously used. If the Member’s status is pending or invited, they will be updated to active. 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.

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 OTP SMS Authenticate endpoint, TOTP Authenticate endpoint, or Recovery Codes Recover endpoint to complete the MFA step and acquire a full member session. 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.
