You can configure your Zendesk Support instance to be open, closed, or restricted (see Configuring how end-users access and sign into Zendesk Support). This article describes how to set up a restricted Zendesk Support instance, so you can control end-user access through approved email domains.
This means that your Help Center is visible to all users, but only users with email addresses in domains that you approve can register and submit support requests. Any unapproved user’s support request will be either be completely rejected or sent to the Suspended Tickets queue.
Enabling the 'Anyone can submit tickets' option
In a restricted Zendesk Support instance, you enable the option to allow anyone to submit tickets and then use the allowlist and blocklist to accept or reject those requests.
- Click the Admin icon () in the sidebar, then select Settings > Customers.
- Select the Anybody can submit tickets option.
- Click Save tab.
Requiring users to register
After you enable the Anyone can submit tickets option, you can also require your users to register.
Requiring registration means that your users must verify their email addresses and also create a password to submit requests. Unverified users' requests are suspended. If you don't require registration, you can still allow users to register using the Sign Up link in your Help Center. users still have the option of registering themselves.
To require that your users register
- Select the Ask users to register option, which is displayed when you select the Anyone can submit tickets option.
Note: This option is not available until you enable Guide (see Getting started with Guide).
Restricting access using the allowlist and blocklist
After you enable the Anyone can submit tickets option, the allowlist and blocklist also appear. You use these to specify the email domains that are either allowed to or prevented from registering and submitting support requests.
