# Where diagrams are stored Saving does POST /rest/api/3/issue/{key}/attachments with a file named <extension>, using your own Jira permissions. The extension comes from the diagram language (mermaid → .mermaid, drawio → .drawio, excalidraw → .excalidraw, and so on). Diagrams therefore appear in the issue's Attachments field and travel with normal Jira attachment handling. Gadget diagrams are the exception. They live in the gadget's own configuration. --- ## What it does As ordinary Jira issue attachments.
