How does Microsoft Flow decide what TLS version to use when using the HTTP Action?

Good morning,

 

We are currently calling a third party endpoint by using the HTTP Action. They show us as using TLS 1.0 when calling them.

Since there is no way to specify the TLS version in the HTTP Action, I would like to know how does it decides internally what TLS version to use. 

The endpoint we are calling is going to disable TLS 1.0 very soon so I would like to know if the HTTP Action will work without any further action from our side, meaning that it will automatically use a higher version when it acknowledges that TLS 1.0 is not longer available in the called endpoint.

 

Thanks,

Renzo Marchena

Hi @Anonymous,

 

I think the TLS version the "HTTP" action uses within Microsoft Flow is based on the the TLS settings of your browser. Please check the TLS settings of your browser on your side, if the TLS settings of your browser contains the the higher TLS version your third party endpoint uses, your flow would continue running when you disable the lower TLS version.

 

The TLS Settings of Chrome Browser, please check the following article:

The TLS Settings of Microsoft Edge Browser or IE, please check the following article:

Please check and see if the following article would help in your scenario:

Thanks for your answer @v-xida-msft. Although in my case, the flow is a recurring one that runs every ten minutes automatically. Hence, I doubt the Browser options have something to do here as user interaction is not required to trigger the flow.
