Parseur webhooks: pick per-row or per-document events on purpose

Choosing a Parseur webhook event: use Document Processed for one payload per document, Table Item Processed when each table row should become its own record (invoice line items), Flattened Tables for spreadsheet-style output, and Export Failed wired to alerts so failed deliveries don't go silent. The payload keys match your template field names exactly, so name template fields like the API contract you want. Test with a temporary logging URL (webhook.site) to inspect the real JSON before connecting production, and protect the production endpoint with a shared-secret header your receiver validates.

Context: Web (Parseur official webhook integration page, parseur.com): documents the four webhook events and what each is for. Document Processed fires when a document is fully extracted, one payload per document with all fields. Flattened Tables fires for documents with tables, spreadsheet-style. Table Item Processed fires once per table row, best for inserting each invoice line item as a separate database record. Export Failed fires when a delivery attempt fails, for error monitoring and alerts. The JSON payload mirrors your template: a field named invoice_number arrives as invoice_number; table fields arrive as arrays of row objects. For production, add a custom HTTP header with a shared secret that your endpoint validates.
