Create a key
Create a key in the app under Account → API: po_sk_ or po_ut_ for REST, po_ut_ or po_gt_ for MCP. A confirmed email is enough. In n8n, store it as a credential of type Header Auth, never in shared workflow exports.
n8n · AI-DMS integration
Use PaperOffice in n8n with the standard HTTP Request, Webhook and MCP Client nodes, no extra package.
OCR, IDP and PDF via REST, events such as document.processed via webhook (from Professional), tools via MCP.
Trusted by leading companies worldwide
How it works
There is no dedicated n8n node. You connect n8n through standard nodes to the REST API, the MCP server and webhook subscriptions. This takes basic knowledge of HTTP and JSON.
Create a key in the app under Account → API: po_sk_ or po_ut_ for REST, po_ut_ or po_gt_ for MCP. A confirmed email is enough. In n8n, store it as a credential of type Header Auth, never in shared workflow exports.
The HTTP Request node calls POST /job/add/{pipeline}. The result arrives in the same response or, after HTTP 202, via GET /job/get/{job_id}. An AI agent in n8n uses the MCP Client with https://mcp.paperoffice.ai/dms.
From Professional: create a Webhook node with a public production URL and subscribe via POST /webhooks/subscribe, for example to document.processed. Every delivery is signed with HMAC-SHA256.
Capabilities
Documented endpoints, signed events and MCP tools, all through standard nodes.
The HTTP Request node reaches every documented REST API endpoint, such as POST /job/add/{pipeline} for OCR, IDP, PDF, translation and voice.
With client_wait, the result arrives in the same response. On HTTP 202, a loop polls GET /job/get/{job_id} until job_status reports completed.
From Professional, a webhook subscription reports document.processed, document.edited, document.tag_added and further document events plus task.completed to your Webhook node.
document.processed carries pofid, workspace_id, document type, key_fields such as invoice number, amount, due date and sender, plus the extracted fields.
Every delivery carries an HMAC-SHA256 signature. You can filter by workspace or document, add your own headers and allow up to 10 retries on failure.
The MCP Client connects an AI agent in n8n to https://mcp.paperoffice.ai/dms via Streamable HTTP or SSE. The available tools follow your plan.
From Professional, a webhook step calls your n8n URL with method, headers, variables such as {trigger.pofid}, HMAC secret and up to 10 attempts.
n8n sends records to the ingest URL of a business data source, from Plus. A connector's wake-up URL starts a folder scan right away.
curl -X POST \ "https://api.paperoffice.ai/latest/job/add/paperoffice_aiocr___generate" \ -H "Authorization: Bearer po_ut_YOUR_API_KEY" \ -F "file=@./rechnung_0917.pdf" \ -F "ocr_mode=complete" \ -F "client_wait=1" curl -X GET \ "https://api.paperoffice.ai/latest/job/get/YOUR_JOB_ID" \ -H "Authorization: Bearer po_ut_YOUR_API_KEY" curl -X POST \ "https://api.paperoffice.ai/latest/webhooks/subscribe" \ -H "Authorization: Bearer po_ut_YOUR_API_KEY" \ -H "Content-Type: application/json" \ -d '{"name":"n8n Rechnungen","url":"https://n8n.example.com/webhook/paperoffice","events":["document.processed"],"filters":{"workspace_ids":[1553]},"headers":{"X-Webhook-Key":"YOUR_N8N_HEADER_VALUE"}}' curl -X POST \ "https://api.paperoffice.ai/latest/webhooks/test" \ -H "Authorization: Bearer po_ut_YOUR_API_KEY" \ -H "Content-Type: application/json" \ -d '{"subscription_id":42}' For developers
Enter the same calls in the HTTP Request node: start a job, poll its status, create and test a webhook subscription.
OpenAPI, a Postman collection, llms.txt and skill.md describe the endpoints, for AI-assisted editors too.
X-PaperOffice-Signature contains sha256= and the HMAC over the raw body. The secret comes with the response to the subscription.
You can also create webhook subscriptions with the MCP tool po_webhooks_subscribe. Which tools are available depends on your plan.
Security and compliance
PaperOffice delivers webhooks only to public addresses, follows no redirects and signs every delivery. Documents are processed in our own EU data center.
Frequently asked questions
No. There is no dedicated node, no ready-made credential and no published templates. You work with the standard HTTP Request, Webhook and MCP Client nodes against the documented REST API and the MCP server.
You create it in the app under Account → API. For REST you use po_sk_ or po_ut_, for MCP po_ut_, po_gt_ or OAuth 2.1; the MCP server rejects po_sk_ and po_pk_. A confirmed email is enough. The API is available in every plan, Free included.
Through a webhook subscription, from Professional. You subscribe to document.processed with the production URL of your Webhook node. The delivery carries pofid, workspace_id, document type, key_fields and the extracted fields. For jobs that n8n starts itself, you poll GET /job/get/{job_id}.
document.processed, document.edited, document.deleted, document.version_created, document.note_added, document.tag_added, document.comment_added, document.lifecycle_changed, document.legal_hold_placed, document.legal_hold_released, document.generated and task.completed. You check the end of an API job via job/get.
For webhooks, yes. PaperOffice delivers only via http or https to public addresses and follows no redirects. Private addresses, localhost and metadata hosts are blocked. For calls to the REST API and the MCP server, n8n only needs outbound access to api.paperoffice.ai and mcp.paperoffice.ai.
No. You create webhook subscriptions via the API with POST /webhooks/subscribe or with the MCP tool po_webhooks_subscribe. POST /webhooks/test sends a test.ping to your Webhook node.
Every delivery carries X-PaperOffice-Signature with sha256= and the HMAC-SHA256 over the raw body. The secret comes with the response to the subscription. You can also have your own header sent along and switch on Header Auth in the Webhook node.
Yes, through the MCP Client with the server URL https://mcp.paperoffice.ai/dms and the Streamable HTTP or SSE transport. Sign-in runs via OAuth 2.1 or a po_ut_ or po_gt_ token. Which tools are available depends on your plan.
Yes, from Plus. Under Knowledge Base AI you create a business data source of the type Push (ingest URL). n8n sends orders, shipments, invoices or quotes as JSON, at most 500 records per call and 60 calls per 10 minutes per source. Chat and phone agents read this data from Professional and write nothing back.
Yes. Every plan allows at least 5 calls per second, 30 per minute, 100 per hour and 500 per day per key, and paid plans allow more. Polling loops count too, so plan pauses of 5 to 10 seconds.
Yes, with the same pattern: the HTTP module in Make, Custom Request in Zapier against the REST API, and an MCP client against https://mcp.paperoffice.ai/dms for AI agents. There are no dedicated apps or modules for Make and Zapier.
Documents that n8n sends to PaperOffice are processed in our own EU data center. What n8n stores itself stays wherever your n8n instance runs, self-hosted or in n8n Cloud.
