Use the Gliffy flowcharting and diagramming API to include flowchart and diagramming editing features in your software. After a user has created a diagram, you will typically want to show an image of that diagram somewhere in your app, so the Document Entity enables you to get a copy of your diagram in the JPEG or PNG format. Use the Account entity, which is an organizational entity primarily for billing and tracking usage. Use the Document entity to access a single Gliffy document or diagram. The User entity gives you access to a named user who is a member of an account. Use the Folder entity to organize documents and control user permissions.
