This is a diagram that describes how Oracle Digital Assistant (ODA) communicates with iOS client apps. The diagram flows from left to right. On the left is an icon representing ODA. There are two parallel arrows (pointing left and right) that are labeled “HTTPS Requests.” Directly to the right of these arrows, is another icon that represents a chat server. It has a single, bidirectional arrow labeled “WebSocket (WSS)” that points to an icon for the iOS Client SDK.
