What Do You Want to Build?
- Extract data from receipts and invoices — totals, tax, dates, merchants, line items, and more, in 205 languages. Start with Data Fields That Taggun Extracts.
- Validate receipts for promotions and loyalty — check submissions against your campaign rules and get pass/fail results in real time. Start with Receipt Validation Fundamentals.
- Detect fraud, duplicates, and tampering — surface duplicate/similarity, tamper, handwriting, and digital-receipt signals for review or workflow decisions before payout. Start with the Fraud Detection Overview.
Two endpoint families cover these supported receipt and invoice workflows: extraction returns structured data from receipt- and invoice-style documents, and validation checks a submission against campaign rules you define. Fraud signals can be returned alongside verbose extraction data when the relevant account capability is enabled and a result is returned for the submitted document. Supported checks can also appear in validation responses when configured for the campaign. Handwriting detection is extraction-only. Not sure which you need? Campaign or promotion with qualifying rules → validation. Other supported receipt and invoice extraction use cases → extraction.
