This guide walks through the complete process of enriching transactions, from preparing your data to processing the results.

​
Preparing Transaction Data

​
Required Fields

Every enrichment request needs three fields: 
{
  "title": "AMAZON MKTPLACE PMTS AMZN.COM/BILL WA",
  "country": "US",
  "type": "expense"
}
FieldTypeDescription
titlestringRaw transaction description (1-256 characters)
countrystringISO 3166-1 alpha-2 country code
typestringexpense or income

​
Transaction Title Best Practices

Don’t truncate or pre-process the transaction title. Include everything from the bank statement: ✓ "POS 4392 STARBUCKS STORE #1234 NEW YORK NY 10001" ✗ "STARBUCKS" The full string contains valuable signals (store numbers, locations, dates) that improve accuracy.
Keep the original case, spacing, and punctuation: ✓ "AMAZON.COM*2K4X9T3H2 AMZN.COM/BILL WA" ✗ "Amazon"
If your transaction source provides additional description fields, concatenate them: javascript const title = [ transaction.description, transaction.merchantName, transaction.locationInfo ].filter(Boolean).join(' ');

​
Country Code

The country code should be:
  • ISO 3166-1 alpha-2 format (2 letters)
  • The country where the transaction originated
  • Uppercase or lowercase (both work)
// Valid country codes
"US"; // United States
"NL"; // Netherlands
"GB"; // United Kingdom
"DE"; // Germany
"FR"; // France
If you’re unsure of the country, use the account holder’s primary country. Transaction strings often contain location hints that Triqai can use for more accurate matching.

​
Transaction Type

Set type based on the transaction direction:
TypeWhen to Use
expenseMoney leaving the account (purchases, payments, fees)
incomeMoney entering the account (salary, refunds, transfers in)
This affects how Triqai interprets the transaction and which categories it considers.

​
Making the Request

​
Basic Request

import Triqai from "triqai";

const triqai = new Triqai(process.env.TRIQAI_API_KEY!);

const result = await triqai.transactions.enrich({
  title: "NETFLIX.COM",
  country: "US",
  type: "expense",
});

​
Processing Multiple Transactions

For multiple transactions, make individual requests. Retries and rate limits are handled automatically: 
import Triqai from "triqai";

const triqai = new Triqai(process.env.TRIQAI_API_KEY!);

async function enrichTransactions(
  transactions: Array<{ description: string; country: string; amount: number }>,
) {
  const results = [];

  for (const tx of transactions) {
    const result = await triqai.transactions.enrich({
      title: tx.description,
      country: tx.country,
      type: tx.amount < 0 ? "expense" : "income",
    });
    results.push(result);
  }

  return results;
}
Transient errors (429, 500, 503) are automatically retried with exponential backoff, so you don’t need to implement retry or rate-limit logic yourself.

​
Processing the Response

​
Successful Response

A successful enrichment returns structured data with an entities array: 
{
  "success": true,
  "partial": false,
  "data": {
    "transaction": {
      "category": {
        "primary": {
          "name": "Entertainment",
          "code": { "mcc": 4899, "sic": 7841, "naics": 532230 }
        },
        "secondary": {
          "name": "Streaming Services",
          "code": { "mcc": 4899, "sic": 7841, "naics": 532230 }
        },
        "tertiary": null,
        "confidence": { "value": 98, "reasons": ["merchant_category_match"] }
      },
      "confidence": { "value": 96, "reasons": [] }
    },
    "entities": [
      {
        "type": "merchant",
        "role": "organization",
        "confidence": {
          "value": 99,
          "reasons": ["name_closely_matched", "results_consensus"]
        },
        "data": {
          "id": "...",
          "name": "Netflix",
          "icon": "https://logos.triqai.com/images/netflixcom",
          "website": "https://www.netflix.com"
        }
      }
    ]
  },
  "meta": {
    "generatedAt": "2026-01-19T10:30:00Z",
    "requestId": "3c90c3cc-0d44-4b50-8888-8dd25736052a123",
    "version": "1.3.13",
    "categoryVersion": "triqai-2026.01"
  }
}

​
Extracting Key Data

import Triqai from "triqai";

const triqai = new Triqai(process.env.TRIQAI_API_KEY!);

const result = await triqai.transactions.enrich({
  title: "STARBUCKS STORE #1234 NEW YORK NY",
  country: "US",
  type: "expense",
});

const { data } = result;
const { entities } = data;

const findEntity = (type: string) => entities.find((e) => e.type === type);

const merchant = findEntity("merchant");
const location = findEntity("location");
const intermediary = findEntity("intermediary");

const processed = {
  category: data.transaction.category.primary.name,
  subcategory: data.transaction.category.secondary?.name,
  confidence: data.transaction.confidence.value,

  merchantName: merchant?.data.name,
  merchantLogo: merchant?.data.icon,

  location: location?.data.formatted,

  intermediary: intermediary?.data.name,
  intermediaryRole: intermediary?.role,
};

​
Handling Different Transaction Types

​
Regular Purchases

Most transactions identify a merchant directly: 
{ "title": "STARBUCKS STORE 1234", "country": "US", "type": "expense" }

​
Intermediary Transactions

When a payment processor or platform is involved: 
{ "title": "STRIPE* ACME INC", "country": "US", "type": "expense" }
Triqai identifies the intermediary (Stripe, role processor) and attempts to identify the underlying merchant (Acme Inc).

​
P2P Transfers

Peer-to-peer payments return both an intermediary and a person entity: 
{ "title": "VENMO PAYMENT TO JOHN DOE", "country": "US", "type": "expense" }
Returns the P2P platform as an intermediary (role p2p) and the recipient as a person entity.

​
Income Transactions

Refunds, salary, and other income: 
{ "title": "PAYROLL ACME CORP", "country": "US", "type": "income" }
Uses income-specific categories and classification logic.
