Product Line Item Extraction
Taggun's Product Line Item Extraction feature captures detailed information about individual products or services on a receipt or invoice.
How It Works
TAGGUN's AI-powered OCR technology identifies and extracts individual line items from receipts and invoices, providing details such as:
- Product or Service Name
- Quantity
- Unit Price
- Total Price
- Product Code
Compatible Endpoints
The productLineItems feature is available only on the verbose endpoints:
Note if you are using Receipt Validation APIs:
All endpoints in the Receipt Validation API support the productLineItems feature.
Enabling Line Item Extraction
To use line item extraction, set the extractLineItems parameter to true in your API request:
curl --request POST \
--url https://api.taggun.io/api/receipt/v1/verbose/file \
--header 'accept: application/json' \
--header 'apikey: YOUR_API_KEY' \ # UPDATE To Your API Key
--header 'content-type: multipart/form-data' \
--form 'file=@/path/to/your/receipt.jpg' \ # UPDATE To Your File Path
--form 'extractLineItems=true'
Remember to replace YOUR_API_KEY with your actual API key and update the file path to your receipt image.

The extracted line items are found in the productLineItems array inside the entities object of the response. Each line item contains:
