API Overview

PSPDFKit Processor provides a simple HTTP-based API for working with documents.

Processing a Document

To process a document, submit a multipart/form-data request to the POST /process API endpoint.

Available headers for POST /process:

• Optional — Authorization — This is where you pass in your JSON Web Token (JWT).

• Optional — pspdfkit-pdf-password — This is where you pass in the password required for the PDF document to be processed. If it’s not set and a password is required, the request will fail.

• Optional — X-Request-Id — If this is set, log statements associated with the HTTP request are marked with a request_id=<request-id> label. Logs correlated with the same request have the same request ID. This helps you determine which request triggered a specific response and what errors or warnings were emitted during request processing. The request ID needs to be between 20 and 200 characters long.

Available parameters for POST /process:

• Required — "file", "url", or "generation".

  • "file" — The document that should be processed.

  • "url" — A URL the document that should be processed can be fetched from.

  • "generation" — A JSON object describing how the document should be generated. See the PDF Generation Schema guide for more information.

• Optional — "operations" — The JSON object describing the operations that should be performed on the supplied document. For all available operations, see the Available Operations guide.

• Optional — Attachment data for the operations — For example, the XFDF that should be imported when using the applyXfdf document operation.
