Open the chat and click the Add members icon in the top-right corner. Then open the Guests tab.

You can invite a guest in three ways:

By link. Click Copy link and send the link to the guest. They can open it and join the chat right away. They do not need to register or install an app.

By email. Enter the guest's email address in the Enter guest email or phone number field and click Add. The guest receives an email with a link to the chat.

By SMS. This option is available only in the cloud version of Bitrix24. Enter the guest's phone number and click Add. The guest receives an SMS with a link to the chat.

In Messenger, open the chat and tap the chat name in the header to open the sidebar. From there, copy the invitation link or invite a guest by SMS, email, or QR code.

Copy the invitation link. In the chat sidebar, tap Chat invite link and select Guest link. The link is copied to your clipboard. Send it to the guest using any app.

Choose an invitation method

1. Open the Members tab and tap Add.
2. Open the Guests tab. To copy the invitation link from here, tap Invite via link.
3. To invite a guest by SMS, email, or QR code, tap Other ways to invite and select an option.

By SMS.

2. For each address, enter the name to display in the chat and confirm the invitation. The guest receives an email with a link to the chat.

By QR code. Show the QR code to the guest, for example, during an in-person meeting. The guest scans the code with their phone camera and opens the invitation.

When guests open the invitation link, they can join the chat without registering in Bitrix24 or installing an app. Before joining, they can enter a name or skip this step.

Guests can access only this chat and nothing else in your Bitrix24. The chat header shows how many guests have joined. Guests can send messages in the group chat and message chat members directly. They can only see messages sent after they join the chat.

A guest can leave the chat when the discussion ends:

1. Open the sidebar.
2. Click More (...) in the top-right corner.
3. Click Leave.

After the guest taps the link, the Bitrix24 mobile app launches. Before joining the chat, they can enter a name.

Guests can send messages in the group chat and message chat members directly. They can only see messages sent after they join the chat.

Reset the invitation link. Use this option to revoke access for all guests who joined with the current link. For example, reset the link when a project ends or external participants no longer need access.

Anyone who can invite guests can also reset the link. By default, this includes the chat owner and moderators.

1. Click the Add members icon in the top-right corner.
2. In the panel, click the arrows icon to reset the link.

All guests who joined with the current link are removed, and the old link stops working.

You can also reset the link from the chat sidebar:

2. Click Three dots (...) next to the invitation link.
3. In the Guest link section, click Create new link.

Remove a specific guest. Use this option to remove one guest without affecting the others. For example, you can remove a contractor who has finished their work while keeping the client in the chat.

After you remove a guest, they lose access to the chat. If the invitation link is still active, they can use it to join again. To block their access, reset the link after removing them.
