What do I need for a callback API service to connect to my server via SSL?

Question

I need to use an API that passes information to a callback script on my server.

The API connects using Secure Sockets Layer (SSL). I've never worked with SSL and I don't know if I need to get some kind of certificate to get it to work on my Server.

I'm using PHP and these are all the current settings related to SSL that I could find via phpinfo():

---

Registered Stream Socket Transports: tcp, udp, unix, udg, ssl, sslv3, sslv2, tls

SSL Yes

SSL Version OpenSSL/0.9.8b

OpenSSL support enabled

OpenSSL Library Version OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008

OpenSSL Header Version OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008

Native OpenSSL support enabled

So what do I need to do in order for the API to connect to my server via SSL?

Also, will I have to use https in the URL of my callback script?

Answer 1

For your server to be accessed via SSL, you do need a certificate for it on your server. While calling the other server, you would use the https to access it. So if the API that you are calling requires a secure callback via SSL, then you do need the certificate. Otherwise, you do not.
