Diagram
PlantUML Sequence
Use a PlantUML sequence to show API messages and the valid or invalid response paths.
plantuml-sequencePlantUML · sequence
Source syntax
Write one diagram from @startuml to @enduml. OPF reads selected PlantUML constructs and adapts them to the shared renderer; it does not run PlantUML, a JVM or preprocessing.
Alt text
The author posts a deck to the API, which saves it in the store. A valid deck returns 201 Created; an invalid deck returns 422 findings.
Markdown
A plantuml fence carries PlantUML source; alt is its text alternative.OPF Markdown
