EU REST API New IP additions Action Required
Scheduled for Sep 24, 02:00 - 04:00 UTC
Scheduled
Dear Customer,

As Sinch continues to invest in a robust and secure operating environment, we will introduce new IP addresses from which callbacks for our REST API endpoint in Europe (eu.sms.api.sinch.com / geo.sms.api.sinch.com) will originate.

If you receive callbacks from Sinch REST API in Europe (eu.sms.api.sinch.com / geo.sms.api.sinch.com) and you have network restrictions in place to restrict access to Sinch IP's only, you are recommended to white list / allow the following IP's before the 24th of September to ensure continued reception of Delivery Receipts and MO messages.

3.122.121.231
18.159.178.180
18.158.33.72

Best regards,
Sinch infrastructure and product management teams.
