Good Afternoon,

I'm attempting to use a Data Factory Data flow to connect to a REST endpoint which will join against records in a CosmosDb, after some decisions within the dataflow, I'll then need to make a few posts to a REST endpoint.

When testing this REST service in postman, it works fine; but in Data Factory, no. I scripted the Postman code into a RestSharp script and discovered that the REST endpoint only accepts TLS 1.2 connections.

Is there a way to force only TLS 1.2 connections from Data Factory to the REST endpoint, either in the Data flow, Dataset or Linked Service?

Thanks,

Hi @JK ,

Welcome to Microsoft Q&A Platform. Thank you for posting query here.

It seems Azure data factory uses by default TLS version 1.2 for data encryption in Transit. Click here to know more about it.

Please check below link to know about Security considerations for data movement in Azure Data Factory.

May be you can try prefix https:// in REST endpoint and see if that works? Also, Please try to enable "Server certification validation" inside linked service and see?

Please let us know how it goes and please share error message details if any. Thank you.
