Using SSL Certificate for WCF-BasicHttp Send Adapter in Biztalk

Hello Everyone,

I have a business process which send messages to SAP via soap endpoint exposed by them.
As you can see below, earlier the url was http, now they have moved their system to cloud so now they have https endpoints.

I wanted to test this change from http->https, so I have modified the url to https, fill in the credentials for basic auth. it working fine in Test system without SSL Certificate, I need to make sure it wont cause any issue after moving to production system.

My Question is,
1/ Will it work in Production system too as its in TEST without SSL Certificate ?
2/ or Do I need to apply SSL for WCF-BasicHttp Adapter, if yes How can I do that ??

Thanks in advance!
