Frequently asked questions

What invoice formats does DocuParse API accept?

DocuParse API accepts PDF, JPG, PNG, and CSV files. Both digital invoices and scanned paper invoices are supported.

What JSON fields are returned for an invoice?

The response includes merchant, invoice_id, document_id, date, due_date, total, subtotal, tax, currency, payment_method, merchant_email, merchant_address, line_items, and extraction_source.

Does it work with scanned invoice images?

Yes. DocuParse handles scanned invoice images automatically. The extraction returns the same named fields regardless of scan quality.

Are line items returned for every invoice?

Line items are extracted when they are present on the invoice. The line_items array includes description, quantity, and amount for each line entry found.

Can I use the extracted JSON in my accounting workflow?

Yes. The structured JSON fields — invoice ID, vendor, due date, total, tax, and line items — map directly to the data your accounting software or automation workflow needs.

How do I authenticate requests?

Use an API key in the Authorization header as a Bearer token. Generate your API key from the DocuParse dashboard after signing up.
