Build automated document processing pipelines
Document processing doesn't scale with synchronous requests
When documents arrive in bulk (from email, file uploads, or storage triggers), processing them synchronously creates bottlenecks. Long-running requests time out, error handling becomes complex, and your users wait.
Scaling out with queues and workers requires significant infrastructure. What you need is an async extraction service that handles the queue, processing, and result delivery for you.

Building async queues requires significant infrastructure
Retry logic for failed jobs adds engineering complexity
Batch volumes spike unpredictably, hard to scale
Event-driven document processing, out of the box
Parselyze handles the async queue, processing, retries, and delivery. You submit documents, receive webhooks, act on results.
Upload or queue documents
Submit documents via REST API or SDK as they arrive, from email, storage, or file upload.
Parselyze processes async
Jobs are queued and processed in the background. No blocking, no timeouts.
Receive webhook notification
Parselyze POSTs the result with HMAC signature to your endpoint when the job completes.
Push to your systems
Write the structured result to your database, trigger a workflow, or call another API.
Webhook payload when a job completes
This is the payload Parselyze POSTs to your endpoint.
Webhook delivery
- POST to your endpoint with the full extraction result
- HMAC-signed via
x-parselyze-signatureheader - Automatic retries on delivery failure
- All events logged in Job History dashboard

Typical pipeline use cases
Email Document Ingestion
Parse attachments received by email and automatically extract and store their data.
S3 / Storage Triggers
Trigger extraction jobs whenever a new file lands in an S3 bucket or cloud storage folder.
Batch Processing
Submit thousands of documents in bulk and process them all asynchronously via webhook.
Multi-step Workflows
Chain extraction with validation, enrichment, and routing steps in a single event-driven pipeline.
A complete pipeline in under 30 lines
Submit a document, register a webhook endpoint, and receive the structured result when processing completes. Every delivery is HMAC-signed for security. No polling required.
