Exports

Sending a project inline? When you pass project instead of project_id, the render runs on Rendley's servers — it has no access to your browser's memory, blob URLs, or local files. Every image, video, and audio entry in the project's library.media array must therefore carry a permanentUrl pointing at a public http:// or https:// address, or the request is rejected with 400 MEDIA_MISSING_PERMANENT_URL. See Export a project inline for a complete example.

Create an export

POST/v1/export

Start an export render job. Provide either `project_id` (a project stored on Rendley) or `project` (render-ready project JSON), but not both. When sending `project` inline, every media item referenced in the JSON (video, image, audio, font) must use a permanent, publicly reachable URL so the render server can resolve and download it; expiring/signed URLs will fail the render. The response returns a job ID; poll `GET /jobs/{id}` for status and the resulting file.

Request body

Name	Type	Required	Description
`project`	object	Optional	Render-ready project JSON to export inline, used instead of project_id when the project is not stored on Rendley. Every media item referenced in the JSON (video, image, audio, font) must use a permanent, publicly reachable URL so the render server can resolve and download it. Temporary or signed URLs that expire will cause the render to fail.
`project_id`	string	Optional	ID of a project already stored on Rendley to export. Provide either project_id or project, not both.
`settings`	object	Optional	Optional render settings. Defaults are applied when omitted.
`settings.codec`	"h264" \| "vp8"	Optional	Optional. Video codec to render with. Defaults are applied server-side when omitted.
`settings.quality`	"high" \| "medium" \| "low"	Optional	Optional. Render quality. Higher quality produces larger files.
`settings.target_resolution`	"720p" \| "1080p" \| "4K"	Optional	Optional. Output resolution. Defaults are applied server-side when omitted.
