Which protocol is normally used with REST APIs?

Representational state transfer (REST) APIs normally utilize Hypertext Transfer Protocol (HTTP) for moving data. It performs this via a get URI and it receives a response in XML, JSON, or another data transfer language. Although you can encrypt the HTTP traffic with SSL (HTTPS), its core language is still HTTP. Simple Network Management Protocol (SNMP) and Simple Network Time Protocol (SNTP) are not used with REST APIs. Simple Object Access Protocol (SOAP) is considered an alternate technology to REST for API access.
