Sort or search the Hosts list

To sort the Hosts list, click any column header (Name, Environment, or Last Requested) to sort the list in ascending or descending order.

To search the Hosts list, type a search term in the Search Hosts box.

Create allowlists that specify hosts that are authorized to send Target requests to Target.

You can create an allowlist that specifies hosts (domains) that are authorized to send Target requests to Target. All other hosts generating requests get a commented-out authorization error response. By default, any host that contains a Target request registers with Target in the Production environment and has access to all active and approved activities. If this approach is not desired, you can instead use the allowlist to record specific hosts that are eligible to make Target requests and receive Target content. All hosts continue to display in the Hosts list, and environments can still be used to group these hosts and assign different levels to each, such as whether the host can see active and/or inactive activities.

To create an allowlist:

  1. From the Hosts list, click Authorize Hosts.

  2. Enable the Enable Authorized Hosts for content delivery toggle.

  3. Add the desired hosts in the Host contains box, as desired.

    Multiple hosts can be listed, each on its own line.

  4. Add the desired hosts in the Host does not contains box, as desired.

    Multiple hosts can be listed, each on its own line.

  5. Click Save.

If a Target request is made on an unauthorized host, the call responds with /* no display - unauthorized mbox host */.

IMPORTANT
Security best practices: If you use ubox functionality of Target, this allowlist also controls the list of domains to which your redirectors can navigate. Ensure that you add any domains to which you want to redirect when you use ubox as a part of your implementation. If the allowlist is left unspecified, Adobe is not able to verify the redirect URLs and protect from potential malicious redirects.
The allowlist takes precedence over environments. Clear out all hosts before using the allowlist feature, then only the hosts allowed by the allowlist appear in your hosts list. You can then move the hosts into the desired environment.

Sometimes domains from other sites appear in your environments. A domain appears in the list if the domain calls at.js. For example, if somebody copies one of your web pages to their server, that domain appears in your environment. You might also see domains from spider engines, language translator sites, or local disk drives.

In cases where mboxHost is passed in an API call, conversion is recorded for the environment that is passed in. If no environment is passed, the host in the call defaults to Production.

You can also create a denylist that specifies hosts (domains) that cannot send Target requests to Target by adding the desired hosts in the Host Does Not Contain box.

NOTE
The Authorized Hosts list is used for both Target hosts and default redirect hosts. Add all existing domains approved to use the Adobe Target JavaScript SDK (at.js) AND all domains used in ubox default redirect URLs. Add any new similar domains to the allowlist in the future.

Delete a host

You can delete a host when it is no longer needed.

  1. From the Hosts list, click the Delete icon.
  2. Click Delete to confirm the deletion.
NOTE
The host is listed again if anyone browses to a page that contains a Target request on the host.

Troubleshooting hosts

Try the following troubleshooting tips if you experience problems with your hosts:

Host does not appear in the list for your account.

  • Refresh the Hosts page in your browser.
  • Confirm that the Target request is correct, including the at.js reference.
  • Try browsing to one of the Target requests on the host. It’s possible that no Target request on the host was ever rendered in a browser.

Random or unknown domains appear in the Host list.

A domain appears in this list if a request to Target is made from the domain. Often, you could see domains from spider engines, language translator sites, or local disk drives. If the listed domain is not one your team uses, you can click Delete to remove it.

My Target request returns /* no display - unauthorized mbox host */.

If a Target request is made on an unauthorized host, the request responds with /* no display - unauthorized mbox host */.
