Configure trust settings to allow Ziflow domains and IP addresses to ensure that reviewers can access proofs, receive email notifications, and view proofs of websites URLs. For information about adding IPs to your allowlist in Ziflow, see Configure your IP allowlist.

Allow the entire Ziflow platform

If reviewers cannot see proofs or comments, make sure HTTPS and WSS traffic is allowed for the following domains:

Data center:

• .ziflow.io
• .ziflow.com
• prod-ziflow-proofs.s3.amazonaws.com
• .auth0.com
• https://proof-proxy.ziflow.net/

WebSockets (WSS) are specifically required for the *.ziflow.io domain to enable real-time communication and proof updates.

EU data center:

• ziflow.eu
• ziflow.com
• auth0.com
• https://proof-proxy-eu.ziflow.net

Allow Ziflow emails

Ziflow sends system and notification emails to inform users and reviewers about new proofs to review and activity updates.

If you are not receiving these email notifications from Ziflow, they may be getting blocked by your spam filters or security settings.

Work with your IT team to add Ziflow to your allowlist or safe sender list. Allow emails from these domain and IP addresses:

• Domain: ziflow.io (e.g., no-reply@ziflow.io, ziflow@ziflow.io)
• IP addresses:
  • 54.240.44.42
  • 54.240.44.43

EU data center:

• Domain: ziflow.eu (e.g., no-reply@ziflow.eu, ziflow@ziflow.eu)
• IP addresses:
  • 24.110.77.133
  • 24.110.77.132

Allow Ziflow to create website proofs

If you are proofing websites in Ziflow and your site has restricted access, you will need to allow Ziflow's public IP addresses to create a static or live proof of your website.

Allow HTTPS and WSS traffic for these IP addresses:

Allow the Ziflow bot

When you create a website proof, Ziflow visits the page with a bot that identifies itself with this user agent:

ZiflowBot/1.0 (+https://www.ziflow.com/bot)

If your site uses bot protection, such as Akamai Bot Manager or Cloudflare, add the Ziflow bot to its allowlist. Otherwise, your site may block or slow down the bot, and the proof can take several minutes or fail.

To make sure your rule keeps working, allow any user agent that contains Ziflow, not one exact value.

The Ziflow bot only visits pages that Ziflow users submit for review. It does not crawl your site or follow links. For more information, see ZiflowBot.
