http.client and https certificate errors

I'm familiar with using http.client in a custom endpoint to get data from 3rd party sites. Is there a way to instruct http.client to ignore https certificate errors? The 3rd party site serves data only over https, but right now it doesn't have a valid SSL certificate. The server name doesn't match the certificate name . An example of the error I'm seeing from the http.client call:

Certificate for <example.com> doesn't match any of the subject alternative names
