Salesforce disabling TLS 1.0 – How to get it working for API calls via BizTalk

Posted on

Salesforce will soon be disabling TLS 1.0 support.

Starting in June 2016, Salesforce will begin disabling the TLS 1.0 encryption protocol in a phased approach across impacted Salesforce services. The disablement of TLS 1.0 will prevent it from being used to access the Salesforce service within inbound and outbound connections.

More Details

In Continuation to the great post on how to call salesforce APIs via BizTalk , the WCF behaviour can be extended to inforce any other TLS protocol.

ApplyClientBehaviour method can be modified to apply security protocol on the outgoing messages. By default this is SSL 1.0


You can pass on the parameter from the configuration like the other params.



WCF Behaviour extension would look something like.

    Reblogged this on BizTalk musings and commented:
    An approach we were considering to keep BizTalk connecting to Salesforce when they disable TLS 1..0

    Great, just what we need to do as well, and we even use that OAuth component (although we’ve altered it to store the credentials in a SSO Affiliate Application)

      Ya true.. Infact we also have the credentials and keys in SSO Affiliate. Makes it easier to manage and stands out for security..
      Would also like to mention that Salesforce can handle the settings per organization as well when contacted. We resently had this issue, where the SSL was upgraded but then some internal connector/ application was failing and so Salesforce reverted the SSL change for our organization for the time being till the connectors starts working with upgraded SSL..
