    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 (opens in new tab)

Archive proof

Rewindex commits each version of an incident it captures to a daily checkpoint, chains it to the day before, and has the checkpoint timestamped by FreeTSA and DigiCert. That proves this record existed by then and has not been changed since, by anyone, Rewindex included.

How the archive is checked, and what it cannot prove.

Impact, status and times are the vendor’s own, as last archived. View on status.sinch.com (opens in new tab).
