Rotate PDF Pages
To rotate pages of a document, use Document Engine’s /api/build
endpoint(opens in a new tab).
- Ensure Document Engine is up and running.
- Send a multipart POST request(opens in a new tab) with instructions to Document Engine’s
/api/build
endpoint.
For more information, refer to the API reference to learn about the /api/build
endpoint and all the actions you can perform on PDFs with Document Engine.
For an overview of multipart requests, refer to the brief tour of multipart requests blog post.
Rotating Pages of a File on Disk
Send a multipart request to the /api/build
endpoint(opens in a new tab), attaching input files and the instructions
JSON:
The example below rotates the first two pages of an eight-page document 90 degrees clockwise. After rotating the first two pages, the result is merged with the remaining six pages of the document to get the final output PDF.
curl -X POST http://localhost:5000/api/build \ -H "Authorization: Token token=<API token>" \ -F document=@/path/to/document.pdf \ -F instructions='{ "parts": [ { "file": "document", "pages": { "start": 0, "end": 1 }, "actions": [ { "type": "rotate", "rotateBy": 90 } ] }, { "file": "document", "pages": { "start": 2, "end": 7 } } ]}' \ -o result.pdf
POST /api/build HTTP/1.1Content-Type: multipart/form-data; boundary=customboundaryAuthorization: Token token=<API token>
--customboundaryContent-Disposition: form-data; name="document"; filename="document.pdf"Content-Type: application/pdf

Rotating Pages of a File from a URL
Send a multipart request to the /api/build
endpoint(opens in a new tab), attaching a URL pointing to an input file and the instructions
JSON.
The following example rotates all the pages of the document at the URL 90 degrees clockwise:
curl -X POST http://localhost:5000/api/build \ -H "Authorization: Token token=<API token>" \ -F instructions='{ "parts": [ { "file": { "url": "https://pspdfkit.com/downloads/examples/paper.pdf" }, "actions": [ { "type": "rotate", "rotateBy": 90 } ] } ]}' \ -o result.pdf
POST /api/build HTTP/1.1Content-Type: multipart/form-data; boundary=customboundaryAuthorization: Token token=<API token>
--customboundaryContent-Disposition: form-data; name="instructions"Content-Type: application/json
{ "parts": [ { "file": { "url": "https://pspdfkit.com/downloads/examples/paper.pdf" }, "actions": [ { "type": "rotate", "rotateBy": 90 } ] } ]}--customboundary--
