Batch Operations
Process multiple documents at once using CargoLint's batch upload and download features.
Overview
CargoLint supports batch operations for uploading multiple documents and downloading them together, making it efficient to handle shipment-level document sets.
Batch Upload
Upload multiple documents as part of a batch by providing the same uploadBatchId across multiple upload requests:
# Generate a batch ID (any valid GUID)
BATCH_ID="550e8400-e29b-41d4-a716-446655440000"
# Upload documents with the same batch ID
curl -X POST "https://api.cargolint.com/api/v1/documents?uploadBatchId=$BATCH_ID" \
-H "X-API-Key: YOUR_API_KEY" \
-F "file=@invoice.pdf"
curl -X POST "https://api.cargolint.com/api/v1/documents?uploadBatchId=$BATCH_ID" \
-H "X-API-Key: YOUR_API_KEY" \
-F "file=@packing_list.pdf"
curl -X POST "https://api.cargolint.com/api/v1/documents?uploadBatchId=$BATCH_ID" \
-H "X-API-Key: YOUR_API_KEY" \
-F "file=@bill_of_lading.pdf"
File Limits
- Maximum file size: 5 MB per file
- Supported formats: PDF, PNG, JPG, TIFF
Each document in a batch is processed independently through the extraction pipeline.
Batch Document Retrieval
Retrieve all documents that belong to a batch:
curl -X GET "https://api.cargolint.com/api/v1/documents/{document_id}/batch" \
-H "X-API-Key: YOUR_API_KEY"
This returns all sibling documents uploaded with the same batch ID.
Batch Download (ZIP)
Download all original documents from a batch as a single ZIP archive:
curl -X GET "https://api.cargolint.com/api/v1/documents/batch/{batch_id}/download" \
-H "X-API-Key: YOUR_API_KEY" \
-o shipment_documents.zip
Shipment Labels
Apply a shipment label to organize batch documents:
curl -X PUT "https://api.cargolint.com/api/v1/documents/{document_id}/shipment-label" \
-H "X-API-Key: YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{"shipmentLabel": "SHIPMENT-2026-042"}'
When applied to a document in a batch, the label is applied to all sibling documents in the same batch.
Best Practices
- Use batch IDs to group documents that belong to the same shipment
- Apply shipment labels for easy identification and filtering
- Download batch ZIPs for archival and offline review
