Response

{
  "status": "SUCCESS",
  "totalParts": 3,
  "fileName": "chapter.pdf",
  "urlValidUntil": "2025-01-01T02:00:00.000Z",
  "urls": [
    "https://s3.amazonaws.com/.../chapter_1.pdf",
    "https://s3.amazonaws.com/.../chapter_2.pdf",

  ]
}
The response contains an array of urls, each pointing to a split part of the original PDF. Parts are named using the pattern {filename}_{partNumber}.pdf (e.g., chapter_1.pdf, chapter_2.pdf).

​
Split Modes

There are two ways to split a PDF:

​
Intervals Mode (default)

Splits the PDF every N pages. For example, a 10-page PDF with interval: 3 will produce 4 parts: pages 1-3, 4-6, 7-9, and 10. 
{
  "url": "https://example.com/document.pdf",
  "splitMode": "intervals",
  "interval": 3
}

​
Ranges Mode

Splits the PDF by specific page ranges. Use comma-separated ranges like 1-3,5,7-10. 
{
  "url": "https://example.com/document.pdf",
  "splitMode": "ranges",
  "ranges": "1-3,5,7-10"
}
When using splitMode: "ranges", the ranges parameter is required. When using splitMode: "intervals", the interval parameter is required.
