| What does it do? | Restore a previous version of a hosted diagram. |
| What does it take? | A JSON body of type RestoreDiagramVersionBody. |
| What does it return? | Status 200 with a body of type EditedDiagram. |
| What can go wrong? | 400 the body is not valid; 401 not signed in; 403 the plan does not include the editor (plan.editor_not_included), the picture does not fit the plan (hosting.quota_exceeded), an organisation the account belongs to requires its members to publish to its library (orgs.publish_required), or the request came from an origin that may not make changes; 404 no such diagram or version; 409 locked (hosting.diagram_locked), saved since (diagram.version_conflict), or another diagram already has this picture (diagram.duplicate_content); 429 too many requests; 502 the diagram could not be stored; 503 hosting is not set up on this server. Every failure uses the one error envelope. |
What it does
Makes the version the diagram's picture, with the checks and the answer of a save. The current picture becomes a version and the picture link changes.

Response body
A 200 answer has the type EditedDiagram.
| Field | Type | Required | Description |
|---|---|---|---|
id | string | yes | The handle for managing the diagram (delete). It is not in the link. |
url | string | yes | The public address of the SVG. Anyone with the link can see it; the token in it cannot be guessed. |
name | string | null | yes | The label given at publish, or null. |
folder | string | null | yes | The folder it is filed in, such as Payments/Checkout, or null for the top level. |
theme | "light" | "dark" | "auto" | yes | The color scheme it was drawn in: light, dark, or auto. |
bytes | integer | yes | Size of the stored SVG in bytes. |
createdAt | integer | yes | When it was first published, in milliseconds since the epoch. |
publishedAt | integer | yes | When it was last published, in milliseconds since the epoch. Publishing the same diagram again moves it. |
expiresAt | integer | null | yes | When it will be deleted, in milliseconds since the epoch, or null when the plan keeps diagrams until you delete them. |
locked | boolean | yes | True while the diagram is locked: it cannot be deleted, renamed or moved until you unlock it. A lock does not stop it expiring on a plan that expires diagrams. |
lockedAt | integer | null | yes | When it was locked, in milliseconds since the epoch, or null when it is not locked. |
warnings | Diagnostic[] | yes | Quality warnings from drawing the source, as draw_diagram gives them. Empty for a restore. |
