Support for Multi-Tenancy Registration with Organization Assignment

[adnan425]

Hi team,

I'm currently building a multi-tenant app using Clerk + Next.js, where each organization has its own custom domain and isolated registration flow.

One challenge I faced is that Clerk's prebuilt components (like ) do not provide a way to pass the orgId or automatically assign users to a specific organization during registration. As a workaround, I had to build a custom sign-up flow using Clerk hooks (useSignUp) to manually attach orgId via publicMetadata, and then use a webhook (user.created) to programmatically add the user to the correct organization.

It would be incredibly helpful if Clerk provided a mechanism to:

• Pass an orgId or similar identifier during registration (e.g. via props or context).
• Automatically associate users with the correct organization based on custom domains or metadata.

This would streamline multi-tenant setups significantly and reduce the need for custom auth flows.

Thanks for the great tool, hoping to see better multi-tenancy support in the future!
