There are two ways to integrate diagrams from a Structurizr workspace into Atlassian Confluence.
The first is to use the built-in HTML Macro, although this needs to be enabled by an administrator on your Confluence installation. To embed a diagram, use the HTML embed code, which you can find by clicking the button while viewing the diagram you would like to embed.
The second approach is to use one of the free Atlassian Confluence macros that have been built specifically to embed diagrams from Structurizr.
The macros can be installed via the Atlassian Marketplace
and then inserted into your Confluence page via the Macro Browser, or by typing
Structurizr workspace embed
This macro embeds a diagram from a Structurizr workspace (cloud or on-premises).
Structurizr Express embed
This macro embeds the Structurizr Express diagram defined in the body of this macro.
The source code for the Confluence macros is open source and available on GitHub, should you want to review or customise them.
When using the Structurizr macros for Atlassian Cloud, none of the data you provide to the macros is stored by us.
