Added capability:Sign
  • Webhook Support on Sign API — subscribe to real-time envelope lifecycle events (created, sent for signature, signed, cancelled, sealed, and more)
Added endpoints:Presigned URLs
  • Request Presigned File URLs — generate presigned upload/download URL pairs to transfer files directly to storage, for larger files than the standard multipart upload supports.
WebhooksImproved endpoints:All Platform endpoints
  • Default limits for asynchronous requests with remote-file (URL) input raised to 300 MB / 2500 pages per document (from 100 MB / 500 pages). Direct uploads and synchronous requests keep the standard 100 MB / 500 pages.
Transformations
  • Merge — limits raised to 1.5 GB (per file and combined) for asynchronous requests with remote-file (URL) input. Other request modes keep the standard limits.
  • Merge — now validates that requests contain no more than 25 input files, and that their combined size does not exceed the 100 MB per-request limit.
  • Watermark — now validates that requests contain no more than 25 input files, and that their combined size does not exceed the 100 MB per-request limit.
Generations
  • Fill Forms — now validates that requests contain no more than 25 input files, and that their combined size does not exceed the 100 MB per-request limit.
Added endpoints:Extractions
  • Extract Fillable Form Data — extract the field data of a PDF’s existing fillable form (AcroForm) — names, current values, field types, and positions — as JSON, XFDF, FDF, or CSV.
Improved endpoints:Extractions
  • Get Properties — the response now includes pageCount, the document’s total number of pages.
Transformations
  • Redact — each redaction now accepts an optional label rendered onto the redaction box in the output (for example, the reason for the redaction).
  • Split — limits raised to 500 MB / 3000 pages for asynchronous requests with remote-file (URL) input. Other request modes keep the standard 100 MB / 500 pages.
Added endpoints:Extractions
  • Smart Detect Form Fields — detect where fillable form fields should be placed in a PDF and return their bounding boxes as JSON.
Transformations
  • Compress — reduce a PDF’s file size. Takes no options and always produces the smallest file; use Optimize for control over the size/quality trade-off.
Generations
  • Fill Forms — generate PDF document with filled form fields.
  • Create Fillable Forms — write detected form fields into a PDF as a real AcroForm, returning a fillable PDF.
Improved endpoints:Generations
  • Fill Forms — now accepts XFDF and FDF data files in addition to CSV and JSON.
Added endpoints:Transformations
  • Watermark — add text or image watermarks to one or more pages of a PDF. Useful for marking documents as drafts, confidential, or applying branding overlays.
  • Optimize — optimise a PDF for a specific use case: web (linearises for fast browser loading), print (preserves full resolution and colour profiles), or minimal (aggressive file-size reduction without visible quality loss).
  • OCR — apply Optical Character Recognition to scanned or image-based PDFs, producing a searchable, text-selectable output document.
Extractions
  • Invoice — extract structured invoice data from a PDF, including vendor details, line items, quantities, unit prices, totals, tax amounts, and payment terms.
Conversions
  • PDF to PDF/A — convert a PDF to the PDF/A archival format for long-term preservation and compliance. Supports conformance levels PDF/A-1b, PDF/A-2b, and PDF/A-3b.
Additional improvements:
  • Platform API file size limit increased from 25MB to 100MB per request
  • Platform API page count limit increased from 200 to 500 pages per individual document
