Sinch Engage - HTTP support for Sinch Engage APIs ends

Scheduled for Oct 30, 11:00 - 16:00 UTC

Scheduled

We are writing to inform you that after 30 October 2026, Sinch Engage will no longer accept API requests sent over HTTP.
If your integration connects using http:// URLs, you'll need to change them to https:// before then. It's a small change: your API, credentials and integration logic all stay the same.

More information about the change can be found here: https://support.app.sinch.com/hc/en-us/articles/17805834983311-Announcing-the-end-of-HTTP-support-for-Sinch-Engage-APIs
