Transaction enrichment library for Django

Use TxnKit as a transaction enrichment API from Django. This page shows the safe request shape, a short code snippet, and the boundary for keeping sensitive data out of the integration.

Target intent

Django applications enriching transaction rows before display.

TxnKit does not decide accounting treatment or reimbursement approval.

Raw descriptor

PAYPAL *ACME-SUPPLY

Short Django API snippet

response = requests.post(
    "https://api.txnkit.dev/v1/enrich",
    headers={"Authorization": f"Bearer {os.environ['TXNKIT_API_KEY']}"},
    json={"raw_description": request.POST["raw_description"], "country": "CA"},
    timeout=1,
)
return JsonResponse(response.json(), status=response.status_code)

Keep API keys out of browser bundles. For frontend stacks, call a backend route or serverless function that owns the TxnKit request.

API-shaped output

{
  "input": {
    "descriptor": "PAYPAL *ACME-SUPPLY",
    "country": "CA"
  },
  "output": {
    "merchant_name": "Acme Supply",
    "category": "Business supplies",
    "confidence": "medium",
    "signals": [
      "processor_pattern",
      "merchant_alias",
      "category_hint"
    ],
    "warnings": [
      "review_low_confidence_matches_before_showing_logo"
    ],
    "logos": []
  }
}

Low-confidence results should keep fallback labels and warnings visible instead of forcing a guessed logo or website.

When to use

  • You are building in Django and need one-descriptor merchant cleanup through an HTTP API.
  • Your app can keep the TxnKit API key on the server side or inside a trusted serverless function.
  • You need merchant display names, categories, confidence, signals, warnings, and logo-ready metadata.

When not to use

  • TxnKit does not decide accounting treatment or reimbursement approval.
  • Do not use TxnKit to process card numbers, account numbers, full statements, bank credentials, emails, phone numbers, addresses, customer names, or customer PII.
  • Do not use TxnKit when the product requirement is guaranteed merchant identity, every-merchant resolution, or contracted uptime terms.

Proof surfaces

The public contract is POST /v1/enrich, backed by the OpenAPI file, benchmark examples, privacy rules, and deterministic request-path tests.
