Hi,

I have to install a certificate to my API. How to do this? The situation is as follows.

I have a WebApp at my customers server. From a Webshop orders and inquiries are sent. The webapp responds with product-information and recievs orders to the local ordersystem.

When testing this in Postman, I get the warning Unable to verify the first certificate. So I have to install a valid certificate. So says also the client who runs the webshop.

As this is the first time I will do this, it would be very nice to have a detailed checklist of what to do.
