Use case

Accounts Payable Automation with the DocuParse API

Extract vendor, invoice ID, due date, total, tax, and line items from incoming invoices — then route them into your approval and payment workflow. Rule-based parsing reads every field, then an AI model checks the result and corrects what it finds wrong before you get it.

97% field-level accuracy

Tested on 500+ real receipts and invoices

Every result also carries confidence and needs_review.
How we test →

The workflow

1

Ingest

A vendor invoice arrives via email, portal, or storage bucket.

2

Extract

Send it to the endpoint and receive named fields.

3

Create AP record

Build the payable from vendor, invoice ID, due date, total, and tax.

4

Route

Trigger your approval or payment workflow automatically.

Code

Submit the file, then fetch the JSON.

Every sample submits the file, then fetches the result until its status is completed or failed. On Starter and Pro, a webhook can deliver it instead.

# 1. Submit the document
curl -X POST https://docuparseapi.com/api/v1/extract \
  -H "Authorization: Bearer $DOCUPARSE_API_KEY" \
  -F "file=@document.pdf"
# → {"success": true, "document_id": "<id>", "status": "queued"}

# 2. Fetch the result (repeat until "status" is "completed" or "failed")
curl https://docuparseapi.com/api/v1/documents/<id> \
  -H "Authorization: Bearer $DOCUPARSE_API_KEY"

How the extraction works
  1. Read — the document is converted to text with OCR (for images) or parsed directly (for digital PDFs).
  2. Parse — deterministic rules pull out each field and line item and normalize dates and amounts.
  3. Check — the result is scored for confidence: totals are reconciled (subtotal + tax = total), required fields are verified, and formats are validated.
  4. Review — an AI model then reviews every document and corrects the fields it finds wrong, looking hardest at the ones the rules were unsure of.

Every response includes a confidence score and a needs_review flag, so you always know which results to trust and which to double-check.
