submit_feedback
Submit Feedback
Submit manually verified receipt data for a previously scanned receipt, improving Taggun's AI model accuracy over time.
Provide the reference ID of the original scan along with corrected field values. This trains the model to deliver better extraction results for similar receipts in the future.
extract_receipt
Extract Receipt Data
Extract structured data from a receipt or invoice image using OCR and machine learning. Supports submission via **URL** or **base64-encoded image**.
Returns merchant details, amounts, dates, and optionally line items, tax breakdowns, fraud detection signals, and more depending on the detail level chosen.
Use **simple** mode for core fields (total, tax, date, merchant) or **verbose** mode for full extraction including line items, invoice/receipt numbers, QR codes, VAT verification, and tampering detection.
validate_receipt
Validate Receipt
Validate a receipt or invoice against a pre-configured campaign's rules. Checks the receipt against criteria such as eligible merchants, products, purchase dates, and amounts.
Returns whether the validation passed or failed, along with matched products, merchant information, and any fraud detection signals.
Useful for loyalty programs, cashback campaigns, rebate promotions, and warranty verification workflows.
manage_product_categories
Manage Product Categories
Export or upload the product categorization list Taggun uses for product-level purchase categorization.
Use **export** to retrieve the currently saved product categories. Use **upload** to replace or modify categories with a CSV or TSV file.
