The websequencediagrams plugin for confluence works by sending
the diagram text to the www.websequencediagrams.com server and
retrieving the image. Alternatively, you can use a local
installation of WebSequenceDiagrams Startup or Corporate edition to
keep your data out of the cloud.
The confluence plugin works on Confluence 5 and above. Have an
adminstrator go to the "Manage add-ons" page and upload the
plugin from the following URL:
Inside your page, click the + button, navigate to More Macros,
find UML Sequence, and use that.
You can change the style of the diagram using the style parameter.
Accessing premium features
If you have a private installation of WebSequenceDiagrams, you can
enter its URL in the plugin settings. Alternatively, if you have a
subscription, you can generate an API key from Here
(while signed in) and paste it into the plugin settings. After
that, you will be able to access premium diagram features and the
diagram will no longer show the logo.
It is important that the url not end in a "/". Do not end the url with the /.
Version 2.0 (November 8, 2018)
Plugin is rewritten using the latest Atlassian SDK. It no longer
makes attachments to the page, because it was causing problems with
excessive notifications. Additionally, it no longer requires a unique
file parameter for each diagram on the same page.
Version 1.2 (May 26, 2014)
Updated to support international character sets. If international characters are
changed to question marks (?) Then upgrade to resolve.
This version is still available at:
