Receipt Data Extraction API for Developers

Drop-in REST endpoints deliver structured JSON from receipts with 99.9% uptime, webhook callbacks, and SDK samples.

Building OCR plus normalization in-house takes months, requires ML expertise, and still fails on messy receipts. Product teams need production-ready accuracy immediately.

The ReceiptFlow API accepts base64 uploads or file URLs, responds with normalized JSON, exposes confidence scores, and notifies your stack via webhooks. SDKs in JavaScript, Python, and Go ship with rate limiting, retries, and sandbox keys.

The Problem

Product teams want to add receipt processing to their apps, but building it from scratch is a multi-month project. You need OCR infrastructure, ML model training, normalization logic for hundreds of receipt formats, and ongoing maintenance as formats change.

Generic OCR APIs return raw text that still requires complex parsing. Every vendor uses different layouts for dates, totals, and line items. Handling international currencies, VAT labels, and multi-language receipts adds exponential complexity. Accuracy issues force manual review workflows that slow everything down.

Third-party solutions are expensive, have usage limits, or lack critical features like webhooks, batch processing, and confidence scoring. You end up vendor-locked with APIs that don't match your product's needs.

The Solution

ReceiptFlow's API is production-ready from day one. RESTful endpoints accept single receipts for real-time processing or batch jobs for high volume. Upload files as base64-encoded data or provide public URLs for the system to fetch.

Responses include normalized JSON with vendor details, transaction metadata, itemized line items, and payment summaries. Every field includes a confidence score so you can route high-confidence extractions automatically and flag edge cases for human review.

Webhook notifications trigger when processing completes—integrate seamlessly into event-driven architectures. Sandbox and production API keys let you test safely before going live. SDKs for JavaScript/TypeScript and Python include automatic retries, rate limiting, and idempotency.

Step by Step

How It Works

Get API Key

Send Receipt

POST base64 file data or a public URL to our API. Include optional parameters for output customization.

Receive JSON

Get normalized JSON with vendor, date, items, totals, tax, and confidence scores—typically within 2-5 seconds.

Handle Webhooks

For batch jobs, receive webhook events when processing completes. Includes full results and links to downloads.

Why Choose This

Key Benefits

Real-Time & Batch

Process single receipts in 2-5 seconds for real-time workflows, or send bulk jobs for high-volume processing with webhook notifications.

Confidence Scores

Every extracted field includes a 0-100 confidence score. Route high-confidence items automatically; flag low-confidence for review.

Webhook Events

Receive receipt.completed events to trigger downstream workflows. Includes full results, errors, and signed download URLs.

Sandbox & Production

Test safely with sandbox keys that don't count toward billing. Flip to production keys when ready to launch.

99.9% Uptime SLA

Enterprise-grade infrastructure with monitoring, automatic failover, and uptime guarantees for mission-critical applications.

SDK Support

Official SDKs for JavaScript/TypeScript and Python with automatic retries, rate limiting, and idempotency built in.

API Features

The API returns structured JSON conforming to a stable schema: vendor object (name, address, phone, tax ID, website), transaction object (date, time, receipt number), items array (name, quantity, unit price, total for each line item), payment object (subtotal, tax, tax rate, total, currency, payment method, card type), and classification object (category, subcategory, confidence score).

Rate limits start at 10 requests/second on the Starter plan and scale to 50+ requests/second on Pro and Enterprise tiers with burst capacity. All plans include automatic retry logic with exponential backoff for transient failures.

Webhook endpoints receive signed POST requests with HMAC verification to prevent spoofing. Events include receipt.started, receipt.completed, receipt.failed, and batch.completed with full result payloads. Webhook retry logic ensures delivery even if your endpoint is temporarily unavailable.

Who This Is For

Perfect for product teams embedding receipt processing into expense apps, corporate cards, banking portals, fintech lending flows, or accounting tools. Get production-ready accuracy without building an ML team.

FAQ

Frequently Asked Questions

What are the rate limits?

Starter: 10 req/sec, Pro: 25 req/sec, Enterprise: 50+ req/sec with custom burst capacity. Contact us for higher limits.

Which SDKs are available?

Official SDKs for JavaScript/TypeScript and Python are available now. cURL examples work with any language. More SDKs coming soon.

Can I choose data residency?

Yes. Choose EU or US processing regions to comply with data residency requirements. Enterprise plans support custom regions.

How do webhooks work?

Register a webhook URL in your dashboard. We'll POST signed events when receipts complete processing. Includes HMAC signature for verification.

Is there a free tier?

Yes. Free tier includes 10 receipts/month. Sandbox API keys are unlimited for testing but return sample data instead of real extractions.

Can I customize the JSON schema?

Yes. Use field mapping parameters to rename output keys or request additional fields. Enterprise plans support custom schemas.
