Pdfmonkey

PDFMonkey is a PDF generation service built on an HTML/CSS → PDF rendering engine. Templates are designed in PDFMonkey's editor (Handlebars syntax), then the API merges JSON data into the template and generates the PDF. For agents: POST a document creation request with template_id and payload, poll status or receive webhook callback when generation completes, then download from the provided URL. Primary use cases: invoice generation, contract creation, certificate printing, report generation. Async model is clean; generation typically completes in 1–3 seconds. Confidence is docs-derived.

REST API at api.pdfmonkey.io/api/v1. POST /documents creates a document ({document: {document_template_id, payload, meta}}). Payload is a JSON string. Response: document object with id, status (pending/draft/success/failure), download_url (null until success). GET /documents/{id} polls status. Webhook: configure callback_url in template settings; PDFMonkey POSTs to callback URL on status change. DELETE /documents/{id} removes a generated document.

API key auth: Authorization: Bearer {api_key} header. Keys from PDFMonkey Dashboard → Developer Settings → API Keys. Workspace-scoped keys. HTTPS enforced. No OAuth2. Download URLs are time-limited presigned S3 URLs; fetch the PDF soon after generation.

Standard HTTP status codes with JSON error bodies. 401 for invalid API key, 422 for validation errors (missing template_id, invalid payload JSON). Document status: pending → success (download_url populated) or failure (errors array). Webhook delivery: PDFMonkey retries failed deliveries. PDFMonkey uptime at status.pdfmonkey.io.

app.pdfmonkey.io/api/docs provides clear REST API reference with request/response examples. Getting started: sign up (free tier: 20 documents/month), create template in visual editor, integrate via API in under 10 minutes. Handlebars syntax documented with examples. No official SDK; REST is simple enough for direct use.
