SOAP request with a Client SSL Certificate

We (myself and my dev team) are relatively new to Elixir, especially after successfully porting large parts of our API service to Elixir with great results.

However, we’re having an issue getting connected to an upstream SOAP WebService that requires an SSL Client certificate. The wrapper library detergentex seems to be the only real available library for consuming web services, however I cannot find a way to make use of Client SSL certificates in the request, which is required by our service provider.

We currently make use of SUDS in Python to achieve this, however porting to Elixir will have tremendous benefits for parallelisation of these particular requests.

Any help would be massively appreciated!
