Tink transaction cleanup

TxnKit helps Tink cleanup workflows return cleaner merchant display metadata after the transaction feed is already available.

Target intent

clean Tink-fed transaction rows without live vendor calls.

TxnKit sits after open-banking data ingestion.

Raw descriptor

CARD PURCHASE STARBUCKS 04821

API-shaped output

{
  "input": {
    "descriptor": "CARD PURCHASE STARBUCKS 04821",
    "country": "CA"
  },
  "output": {
    "merchant_name": "Starbucks",
    "category": "Coffee shop",
    "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 already receive transactions through Tink cleanup and need cleaner UI rows.
  • You want a one-descriptor enrichment API with bounded response fields.
  • You need fallback warnings for ambiguous descriptors instead of silent overconfidence.

When not to use

  • TxnKit sits after open-banking data ingestion.
  • 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.
