Paid Gliffy accounts can embed Gliffy diagrams into various 3rd party applications. To embed a diagram, click on Share then click into the Embed tab.
By default no links are generated until you click on an application. If you wanted to embed your diagram in HipChat, for example, click on the HipChat icon.
This generates a code that is supported in the HipChat app. Pasting it there will show your Gliffy diagram. All changes show up when refreshed.
If you want to remove the embed links tied to your diagram, click on Deactivate All Embed Links.
