How to set the organizer/host in a collective/team event embed?

[oferk1]

Hi everyone,

I’m trying to control which user appears as the host/organizer in a collective/team event embed in a self-hosted Cal.com setup. Here’s the scenario and what I’ve tried so far:

Scenario:

• I have a team embed URL like:

https://calcom.company.dev/ofer+octopus/reassignment/embed

• The intention is for ofer to always appear as the host, rather than Octopus.
• There are multiple EventType rows: one per user (ofer, octopus) and no team-level row in the DB.
  What I tried:

Adding ?user=ofer → still shows Octopus.

Creating a Team in the DB, adding memberships (Ofer = OWNER, Octopus = MEMBER), updating EventType.teamId → no effect.

Reassigning EventType.userId or teamId → still defaults to Octopus.

Observation:

Embed resolves by slug, not EventType.id or teamId.

Using /ofer/reassignment/embed works, but I need multiple members that arent guests

Question:

Is there a supported way to control the organizer/host in a team/collective event embed?

Any guidance or workarounds are appreciated.

Hi @oferk1! I'm Dosu and I’m helping the cal.com team.

There isn't a direct configuration or URL parameter to control which user appears as the host/organizer in a collective/team event embed. The host shown is determined by how the embed URL slug is parsed and how the backend assigns hosts—usually defaulting to the first or highest-priority member in the slug or database order. Roles like OWNER don't guarantee host display in collective events, and query parameters like ?user=ofer have no effect.

A practical workaround is to set only the desired host (e.g., Ofer) as a Fixed Host in the event type, and add other members as Round Robin hosts. This ensures the Fixed Host always appears as the organizer, but works best when you have just one other member joining besides the host. For more advanced setups, you can use the API to specify host assignments with a hosts array, but the embed display logic is still tied to slug resolution and backend assignment rules, not direct configuration or query strings. More details and examples are available here and here.

If you need guaranteed control over the displayed host for more complex team events, it may require customizing the backend assignment logic or the slug construction.

Hi @dosu, thanks for the detailed explanation!

• You mention workarounds like creating a Fixed Host in the event type or using the API to specify hosts. I haven’t had success applying these in my self-hosted instance.
• According to this reply ([link](How to manage team member in self hosted instance #23663 (comment))), it seems that some of these approaches may be blocked or limited in self-hosted deployments.

Could you confirm whether solutions like **creating teams, assigning Fixed Hosts, or using the API ** are actually applicable in self-hosted Cal.com?

Thanks!

Features like creating teams, assigning Fixed Hosts, and using the API host array are not available in the open-source self-hosted version of Cal.com without a commercial license. These functionalities are explicitly gated behind license checks in both the backend and frontend code, and attempts to use them via the API or UI will prompt for payment or fail to work as expected. This is confirmed by the official documentation and codebase, which state that Teams, Organizations, advanced user management, and related APIs are commercial-only features in Cal.com’s open-core model (source, source). Direct database manipulation does not enable these features in the UI or API without a valid license. There are currently no official workarounds for enabling these features in the free self-hosted version.
