Completes an email link verification flow once we've reached the email link results URL.

function handleEmailLinkVerification(
  params: handleEmailLinkVerificationParams,
  customNavigate?: ((to: string) => Promise<unknown>) | undefined,
): Promise<unknown>

When users click on email links they get redirected to the URL that was provided during email link verification flow initialization. The URL will contain a couple of important query parameters added by Clerk. These are called __clerk_status and __clerk_created_session.

The __clerk_status query parameter is the outcome of the verification and accepts the following values: verified, failed, expired, or client_mismatch. client_mismatch can only be a verification outcome if the Require the same device or browser setting is turned on for sign-ins and sign-ups.

The __clerk_created_session query parameter will hold the ID of the new session, if one was created as a result of the verification. Since the email link can be opened at any device and not the one that originated the verification, the new session ID might not be available under Client.sessions.

Email link flows can be completed on the same device that they were initiated or on a completely different browser. For example, a user might start the email link flow on their desktop browser, but click on the email link from their mobile phone.

The handleEmailLinkVerification() method takes care of finalizing the email link flow, depending on the verification outcome.

Upon successful verification, the method will figure out if the sign in or sign up attempt was completed and redirect the user accordingly. As such, it accepts different parameters for the URL it should redirect when sign-in or sign-up is completed and the URL which it should redirect when the sign-in or sign-up attempt is still pending. Both parameters are optional, but you can provide them to the method up front. The final redirect will depend on the sign-in or sign-up attempt's status.

If the email link verification failed or the link expired, this method will throw a EmailLinkError. Check the error's code property for details.

Additionally, the handleEmailLinkVerification() method allows you to execute a callback if the successful verification happened on another device.

In case the email link verification wasn't successful, the handleEmailLinkVerification() method will throw a EmailLinkError. You can check the error's code property to see if the email link expired, or the verification simply failed.

Take a look at the function parameters description below for more usage details.

    Type
    handleEmailLinkVerificationParams

    to
    Type
    string | undefined
    Description

redirectToSignIn()

Redirects to the sign-in URL, as configured in your application's instance settings. This method uses the navigate() method under the hood.

Returns a promise that can be awaited in order to listen for the navigation to finish. The inner value should not be relied on, as it can change based on the framework it's used within.

function redirectToSignIn(options?: SignInRedirectOptions): Promise<unknown>
  • Name
    options?
    Type
    SignInRedirectOptions | undefined

setActive()

A method used to set the active session and/or organization. Accepts a SetActiveParams object.

function setActive(params: SetActiveParams): Promise<void>

Example

The setActive() method is most commonly used when building a custom flow for your application.

For example, during authentication, when a user signs in or signs up successfully, a new session is created. setActive() needs to be used to set the new session as the active session. See the implementation of this in the Custom authentication flow guide.

Another example is when a user switches organizations in a multi-organization application. setActive() needs to be used to set the new organization as the active organization. See the implementation of this in the Custom organization switcher guide.

signOut()

  • In a multi-session application: Signs out the active user from all sessions
  • In a single-session context: Signs out the active user from the current session

  signOutCallback?: () => void | Promise<any>,
  options?: SignOutOptions,
): Promise<void>
