The figure below left shows how the embedded solution interacts with its embedding webpage and MobileTogether Server. The screenshot below right shows a webpage that contains an embedded solution (framed in green).
This section is organized as follows:
•Embedding a Solution in a Webpage describes how to load a solution into an IFrame element. It contains a complete HTML code listing that you can try out yourself.
•Authentication: Any communication that tries to access a workflow on MobileTogether Server must be authenticated. This section describes the types of authentication that an embedded solution can use. Authentication via JSON Web Tokens (JWT) is a type of authentication that is specific to embedded solutions; it enables these solutions to be conveniently integrated into existing networks and systems.
•Examples: This section contains the code listings of HTML pages that use embedded webpage solutions, together with step-by-step descriptions of the communication process between webpage and server.
The following design mechanisms provide crucial functionality for the Embedded Webpage Solutions feature:
•The OnEmbeddedMessage page event of the solution picks up the message from the webpage
•The $MT_EMBEDDEDMESSAGE JSON page source stores the received data in a structured form
•The Load from String action parses a serialized string and places the deserialized structure in a page source; useful for deserializing an XML string in a JSON node and creating an XML page source
•The Save to String action serializes a page source and places the resultant string in the node of another page source
•The Embedded Message Back action sends a serialized JSON string to the IFrame that loaded the current solution
