Planned maintenance of this endpoint occurs on the second and last Tuesday each month, between 08:00 UTC and 09:00 UTC.

Release notes can be found here: https://developers.sinch.com/docs/release-notes-whatsapp

IMPORTANT: WhatsApp has informed us that starting June 29, they will no longer support the TTL parameter in the API.
As such it is important that you update your backend platform so it does not send TTL as part of the WhatsApp API request.
If your backend system continues to include this past June 29th, the TTL parameter will be ignored.

Below is the information shared by WhatsApp on this:
"TTL is to ensure that a message will be expired (never be delivered), if the message can't be delivered within the TTL window.
After the deprecation, the template messages will work the same as the regular message; there is no more TTL window and instead the message will be delivered as soon as the receiver becomes available"

Dear Client,
As part of our continuous improvements to our platform, we are enhancing our capacity of our platform by bringing up a new site in the US. We will be adding this site to our REST API end points.

This will only impact clients that have IP whitelisting in place for our IPs connecting to:
* api.clxcommunications.com
* api-sms.us.clxcommunications.com
* sms.api.sinch.com
* us.sms.api.sinch.com
* us1.sms.api.sinch.com
* geo.sms.api.sinch.com

The maintenance is scheduled below:
Type: Scheduled Maintenance
Maintenance: REST API

* api-sms.us.clxcommunications.com
* sms.api.sinch.com
* us.sms.api.sinch.com
* us1.sms.api.sinch.com
* geo.sms.api.sinch.com

Additional IP Addresses to be added:
• Clients connecting to Sinch: 52.149.30.26
• Clients accepting DR's or MO's from Sinch: 20.57.179.10, 20.64.177.172 , 20.57.134.31

Please add the additional IP Addresses to the whitelisting (or any IP rules) on your outbound and inbound message flows that may prevent your platform from sending messages to Sinch.

Please ignore the maintenance if your application/organisations uses FQDN's api.clxcommunications.com or the other listed FQDNs and do not use our IP's in your API configurations, IP whitelisting or firewall rules for your outbound traffic to our platform.
If you reach our API platform via an IPSec VPN tunnel, this change will not impact you.

We appreciate your patience and apologise for any inconvenience experienced during this maintenance period.
