2. Automatic sign-up/log-in workflow

For Clerk to work with bubble's sign-up/log-in mechanism, you need to add the Clerk workflow. All actions come from the base bubble Account type. The final result of workflow will look like this:

The workflow must be triggered from ClerkProvider's "Clerk loaded with user" event.

The ClerkProvider element

In order to use Clerk on your page, first you need to add the ClerkProvider element. It can go anywhere, and does not display anything. To create the workflow follow these steps:

1. Create an account for someone else

2. Assign a temp password to a user

3. Log the user in

That's it! Now bubble will recognize your users, and you can use Clerk elements and actions throughout your page.

3. Sign out workflow

For sign out to work, you will need to sign out of both Clerk and bubble. An example sign out workflow is as follows:

When the Signout button is clicked, the action "Account Log the user out" is triggered along with the "Clerk Signout" action.

4. (Preview-only) URL Redirects

In bubble's preview environment, your app will be running on the following URL: /version-test?debug_mode=true. In order to make Clerk work during preview mode, you need to redirect here after adjust your Redirects in the Clerk dashboard to point to this value. ​

Under Paths enter /version-test?debug_mode=true for the following fields:

  • Sign up redirect URL
  • Sign in redirect URL
  • Sign-out redirect, single account URL

The final result should look like this:


The Clerk plugin includes basic actions that allow you to link sign-up, log-in and sign-out processes to your page elements.


The OpenSignup action will open the Clerk sign-up modal.


The OpenSignin action will open the Clerk sign-in modal.


The Signout action will sign out the active user.


The Clerk plugin includes pre-built elements that can enhance your application's user experience.


The ClerkProvider element is the base building block for the integration between your page and Clerk. For actions and workflows to function properly, you need to add a ClerkProvider element anywhere on your page so that actions can reference it.

This element does not display anything.


The UserButton element gives your users an easy way to manage their account(s).

The element should not be visible on page load, as shown below.

To show the UserButton, add a new workflow using a"Clerk loaded with user" event. This workflow will show the UserButton once Clerk has fully loaded. Here's what this workflow will look like:
