    • Safari

Operating system 

No specific operating system is required.

Hardware

  • Memory (RAM): 4 GB or higher

Network bandwidth

Kustomer requires a stable wifi network connection, as events are received and sent in real-time. The recommended network bandwidth is at least 10Mbps download / 5Mbps upload.

Authorized domains

The application must be able to send and receive from the following domains:

  • kustomerapp.com
  • api.kustomerapp.com
  • cdn.kustomerapp.com
  • cdn.segment.com
  • fonts.googleapis.com
  • fonts.gstatic.com
  • heapanalytics.com
  • *.chaotic-static.com
  • *.cloudfront.net
  • *.cloudinary.com
  • *.countryflags.io
  • *.datadoghq.com
  • *.googleusercontent.com
  • *.google-analytics.com
  • *.gravatar.com
  • *.jsdelivr.net
  • *.launchdarkly.com
  • *.materialdesignicons.com
  • *.maxcdn.com
  • *.pusher.com
  • *.pusherapp.com

  • *.pubnubapi.com
  • *.pubnub.com
  • *.pubnub.net
  • *.pubnub.io
  • *.s3.amazonaws.com
  • *.statuspage.io

What should I do if Kustomer gives an error about an authorized domain?

If the computer you run Kustomer on is issued and managed by your employer, speak to your IT department. They'll be in the best position to adjust the needed settings on any VPNs or other software they provide to authorize these domains.

If the computer you run Kustomer on is a personal device, check the settings on any ad blockers or content filters you have running. You may need to add an exception for kustomerapp.com so that traffic is not blocked when using our web app.
