Organisation domain settings
Set the single OmniLab Pages subdomain an organisation uses, and know what the Domain screen can and cannot do.
Give an organisation its own OmniLab Pages web address by setting its subdomain. Each organisation holds one subdomain, so this screen is for a single value, not a list of several addresses.
What to expect on this screen
Each organisation can store one OmniLab Pages subdomain here. If your setup already uses a shared custom domain, this area shows that domain in read-only form instead of an editable subdomain field.
What you can manage here
| Capability | What you can do |
|---|---|
| Add a subdomain | Possible when the organisation does not already have one |
| Remove a subdomain | Possible when a subdomain is already attached |
| Keep several addresses | Not supported from this screen |
| Edit a shared custom domain | Not supported here; it appears in read-only form only |
Add or change an organisation subdomain
Open the Domain tab
Switch to the target organisation, then open General Settings or Organization Settings and select Domain.
Add the subdomain if none exists
If the organisation does not already have a subdomain, click Add Subdomain, enter the value, then submit the form.

Remove first before replacing
If the organisation already has a subdomain and you need a different one, remove the existing value first. There is no direct replace action.
Verify the final organisation state
After saving, confirm that the organisation shows the expected subdomain or, if relevant, the read-only custom domain.
Validation rules
When you add a subdomain, keep these rules in mind:
- an organisation can have only one subdomain at a time
- the subdomain must not already be used by another organisation
- the subdomain must be unique across your whole account
- the subdomain must have at least 3 characters
Where other domain tasks happen
This screen holds one subdomain per organisation. For anything wider, go to the right team or screen instead:
- Plan around a single address per organisation, since that's all this screen stores.
- Ask your IT or hosting team to set up a shared custom domain — that work happens outside OmniLab.
- Have your IT team manage security certificates as part of that custom domain setup.
- Set the subdomain directly on each organisation that needs one — every organisation manages its own domain settings independently.
