TLS warning for developers
When your integration communicates with Omnisend via HTTP, it uses TLS (Transport Layer Security) to ensure data privacy and integrity.
There are multiple major versions of TLS, including v1.0, 1.1, 1.2, and 1.3. Versions 1.0 and 1.1 are deprecated and should no longer be used.
On June 1, 2020, we'll require all communications with Omnisend to use TLS version 1.2 or greater. Using TLS version 1.2 or greater makes Omnisend safer for everyone.
What's changing
On June 1, 2020, we'll require all apps and integrations communicating with Omnisend to use TLS version 1.2 or greater.
What if I do nothing?
If you do nothing and your app or other integration uses TLS version 1.0 or 1.1, Omnisend will refuse your app's HTTP requests beginning June 1, 2020. We encourage you to update your integration before then so your users don't experience any problems.
