# Third-Party Connections and Approved Addresses

When you install Blackthorn Events from AppExchange, Salesforce asks you to approve a list of websites the app is allowed to contact. You cannot deselect individual entries: approving the list is part of installing the package.

This page explains what each entry is for, so your security or compliance team can review the list before you install.

**Being on this list does not mean the connection is in use.** Most of these services only do anything after you set them up in your org. Until then, the entry is approved but nothing is sent to it.

## Third-party services

None of these are contacted unless you configure the matching feature.

| Address | What it is | When it is used |
| --- | --- | --- |
| api.zoom.us, zoom.us | Zoom | Only if you connect a Zoom account for webinar events |
| api.webex.com, webexapis.com | Webex | Only if you connect a Webex account for webinar events |
| api.getgo.com | GoToWebinar | Only if you connect a GoToWebinar account |
| api.sendgrid.com | SendGrid, for sending email | Only if SendGrid is enabled in your email settings |
| auth.getbee.io, api.getbee.io | Beefree, the email template design tool | Only when someone uses the Email Template Builder |
| maps.googleapis.com | Google Maps | Used to turn event addresses into map coordinates |

## Blackthorn services

| Address | What it is | When it is used |
| --- | --- | --- |
| events.blackthorn.io | The public event registration site | Whenever your event pages are viewed |
| lmo.blackthorn.io | Blackthorn licensing | License checks |
| blackthornio-us.us.auth0.com | Authentication for Blackthorn services | Alongside the services above |

| subdock.blackthorn.io | Subscriber Dock | **Not used.** The entry ships with the package but nothing in the app calls it |

## Development and staging addresses

These exist so Blackthorn can test the app before a release. They are never contacted from your production org.

- dev-blackthorn.us.auth0.com
- dev.datasync.blackthorn.io
- dev.capacity-manager.blackthorn.io
- staging.capacity-manager.blackthorn.io

## Checking the list yourself

You can see the approved list in your own org at any time: go to **Setup**, enter **Remote Site Settings** in the Quick Find box, and look for the Blackthorn entries. This page describes the list as of the current release.
