sequence-diagramming

To convert a described flow into a Mermaid sequence diagram, you provide the flow name, participants, and steps. The tool then automatically renders these inputs into a clear Mermaid sequence diagram with correctly ordered participants and messages.

The best way to map API call sequences is to describe one specific flow at a time. This approach renders alternates and loops as distinct Mermaid fragments, preventing diagram duplication and keeping the interaction logic clear.

You should avoid generating multiple error paths in a single diagram. The tool enforces one diagram per flow to maintain clarity, using Mermaid fragments to properly label alternates and error paths without conflating separate use cases.

Yes, the Mermaid diagramming tool requires participants to be defined first. It enforces a left-to-right order, placing participants before messages to ensure the generated sequence diagram accurately reflects the interaction flow.

To show synchronous versus asynchronous calls in a UML sequence diagram, you describe the call types in your flow steps. The tool translates this into explicit Mermaid arrows indicating the exact call direction and type.

You should not use sequence diagrams to draw the underlying implementation details. They are designed to focus purely on interaction flows, so avoid using them when you need to visualize system architecture rather than participant messaging.
