Usage

The @apiclient.xyz/tink library provides an unofficial TypeScript API abstraction for interacting with tink.com. To make the most out of this library, it's recommended to have a basic understanding of TypeScript and asynchronous programming in JavaScript.

Getting Started

First, you need to import the necessary classes from the @apiclient.xyz/tink package. Here’s how you can get started with creating a TinkAccount instance and utilizing it to perform operations:

import { TinkAccount, TinkUser, TinkProviderConsent } from '@apiclient.xyz/tink';

// Initialize a new TinkAccount with your clientId and clientSecret
const myTinkAccount = new TinkAccount('<YOUR_CLIENT_ID>', '<YOUR_CLIENT_SECRET>');

Creating and Managing Tink Users

To interact with user-specific APIs, create a TinkUser object. You can also retrieve an already existing user or create a new one as follows:

// Creating a new Tink User
const newUser = await myTinkAccount.createTinkUser('unique_external_user_id');
console.log('New TinkUser created:', newUser);

// Retrieving an existing Tink User
const existingUser = await myTinkAccount.getTinkUser('existing_unique_external_user_id');
console.log('Existing TinkUser retrieved:', existingUser);

Generating Tink Link for Account Connection

To connect bank accounts to the Tink platform, you will need to generate a Tink Link URL and present it to your users. Here's how you can obtain it:

const tinkLinkUrl = await existingUser.getTinkLinkForMarket({
  countryId: 'SE', // Specify the market code, e.g., SE for Sweden
  redirectUrl: 'https://yourapplication.com/callback', // Redirect URL after account connection
  customState: 'your_custom_state', // Optional custom state to be included in the callback
  testProviderBool: true // Set to true if using test providers
});
console.log('Tink Link URL:', tinkLinkUrl);

Fetching Bank Accounts and Transactions

After the user has connected their bank accounts through the Tink Link, you can retrieve the connected accounts and their transactions:

// Fetching provider consents to get bank accounts
const providerConsents = await existingUser.getProviderConsents();
for (const consent of providerConsents) {
  console.log('Provider consent:', consent);

  // For each consent, get associated bank accounts
  const bankAccounts = await consent.getBankAccounts();
  for (const account of bankAccounts) {
    console.log('Bank account:', account);

    // Fetch transactions for each bank account
    const transactions = await account.getTransactions();
    for (const transaction of transactions) {
      console.log('Transaction:', transaction);
    }
  }
}

Advanced Usage

The library offers advanced features like handling provider consents, refreshing data, and managing users. For instance, you can delete a user as follows:

await existingUser.delete();
console.log('User deleted successfully.');

To explore more about the library, including handling errors, refreshing tokens, and more nuanced data retrieval, consult the official API documentation provided by Tink.com and refer to the TypeScript definitions in this package.

Remember to secure your credentials and tokens appropriately and follow Tink's guidelines for data handling and user privacy.
