# Allowlisting your domain

> Reach out to our team to allowlist your domains before embedding Explo dashboards

<Note>
  Don't forget you may need to also allowlist egress IPs for your [Connectivity
  Region](/data-sources/connecting-to-data-sources/connectivity-regions).
</Note>

You will need to allowlist your development, staging, and production domains in
Explo to enable the embedded component to communicate with our API. For
development purposes, we have `localhost` on ports 3000, 3001, 3002, 6700, 8080
allowlisted already.

To add a allowlist rule, go to the Domain Allowlisting section of the settings
page. There'll you'll see a list of all the rules your team has added, as well
as both a button to add more rules and a text input field that you can use to
test a url against your rules.

The following are notes about how Explo allowlisting works:

* Explo's allowlist supports both hardcoded domains and domains that use an
  asterisk (\*) as a wildcard

  * [https://testing.explo.co](https://testing.explo.co) and https\://\*.explo.co will both allowlist
    [https://testing.explo.co](https://testing.explo.co), but the second rule would also allowlist
    [https://staging.explo.co](https://staging.explo.co)

* A wildcard only applies to a single subdomain (the portion of a url between
  two periods)

  * https\://\*.\*.explo.co would allowlist [https://site.testing.explo.co](https://site.testing.explo.co), but
    https\://\*.explo.co would not

* Wildcards can also be mixed with hardcoded text within a subdomain

  * [https://explo-\*.co](https://explo-*.co) allowlists [https://explo-testing.co](https://explo-testing.co) and
    [https://explo-staging.co](https://explo-staging.co)

* The www is not required for the allowlist rules

  * [https://explo.co](https://explo.co) allowlists both [https://www.explo.co](https://www.explo.co) and [https://explo.co](https://explo.co)

* You must include a protocol (http or https) in your allowlist rule, and this
  cannot be wildcarded

<Note>
  If you want to allowlist ALL domains to view your dashboards, you can add \* as
  a rule
