There are two ways that you could secure your Dropbox Fax API callback url:

Implement Basic Auth
- This would be something like https://username:password@your.domain/callback
- Note that basic auth credentials are redacted on Dropbox Fax's side
Whitelist IPs from Dropbox Fax
- Ask support@hellosign.com for the outbound IP addresses from Dropbox Fax's API

For more information about the callbacks, see the article Can you give me an example of a callback event?

See the article on sending a fax using the Dropbox Fax API for more information.
