n8n Parseur Webhook Workflow: Real-Time Document Parsing

Parse documents in real time with an authenticated n8n Webhook + Parseur

This n8n workflow accepts a document file through a secure webhook, sends it to Parseur for parsing, polls until the parsing is complete, and then returns the extracted JSON result—or a clear structured error—to the calling client.

What this workflow does

• Receives an authenticated POST webhook containing a document in binary form.
• Uploads the document to Parseur using your configured Parseur parser ID, capturing the returned DocumentID.
• Polls Parseur’s Document API to check parsing status, with a brief wait between attempts.
• Retries until completion or timeout: if parsing isn’t finished and the retry limit hasn’t been reached, it waits and checks again while incrementing a retry counter.
• Returns parsed fields as JSON when Parseur reports success.
• Handles failures with structured JSON errors when:
  • Uploading fails (returns an appropriate 400-style response),
  • Parseur’s API is unreachable (returns a 503-style response),
  • Retries are exhausted (returns a 408-style response).

Use cases

• SaaS operators needing document-to-JSON extraction inside an API workflow.
• Automation engineers building real-time parsing endpoints that other systems can call reliably.
• Processing extracted data from uploaded files where Parseur async parsing requires polling and timeouts.

Technical details

• n8n nodes: if, set, wait, webhook, sticky note, n8n-nodes-parseurparseur
• Webhook endpoint: POST the document to /parse-document with header authentication.
• Parseur integration: upload step with Parseur credentials + parser ID, then Document API status polling authenticated via HTTP headers.
• Configurable timing: adjust polling wait times and maximum retry count to match Parseur rate limits and your desired timeout behavior.
