This example assumes you already have a workspace and template set up. For creating templates from scratch, see the Full Workflow guide.
Prerequisites
- A Raydocs API token with
sessions-writeability - An existing extraction template ID
- Documents to process (PDF, PNG, JPG)
The 3-Step Process
1
Upload Files
Upload your documents to temporary storage using signed URLs
2
Create Sessions
Create extraction sessions with
auto_extract: true to start processing automatically3
Get Results
Poll for completion and retrieve your structured data
Complete Example
- Python
- TypeScript
- PHP

Understanding the Response
When extraction completes, you get structured data matching your template schema:Copy
{
"id": "result-uuid-here",
"status": "completed",
"data": {
"invoice_header": {
"invoice_number": "INV-2024-001",
"invoice_date": "2024-01-15",
"total_amount": 1250.00,
"currency": "USD"
},
"vendor_info": {
"vendor_name": "Acme Corp",
"vendor_address": "123 Business St, City, ST 12345"
},
"line_items": {
"items": [
{
"description": "Consulting Services",
"quantity": 10,
"unit_price": 100.00,
"total": 1000.00
},
{
"description": "Travel Expenses",
"quantity": 1,
"unit_price": 250.00,
"total": 250.00
}
]
}
},
"reasoning": {
"invoice_header": {
"invoice_number": {
"reasoning": "Found 'Invoice #: INV-2024-001' in header section on page 1",
"confidence": 0.95
}
}
}
}
Error Handling
Rate Limiting (429)
Rate Limiting (429)
If you hit rate limits, implement exponential backoff:
Copy
import time
def upload_with_retry(client, file_path, max_retries=3):
for attempt in range(max_retries):
try:
return client.upload_file(file_path)
except requests.HTTPError as e:
if e.response.status_code == 429:
wait = 2 ** attempt * 10 # 10s, 20s, 40s
print(f"Rate limited, waiting {wait}s...")
time.sleep(wait)
else:
raise
raise Exception("Max retries exceeded")
Failed Extractions
Failed Extractions
Check the result status and handle failures gracefully:
Copy
results = client.get_results(session_id)
if results and results[0]['status'] == 'failed':
# Log error, retry, or notify
print(f"Extraction failed for session {session_id}")
