Development with FinTag SDK

This section provides guidelines and best practices for developing applications using the FinTag SDK. Whether you’re building a web application, a mobile app, or a backend service, these tips will help you make the most of the FinTag SDK.

​
Best Practices

  1. Keep Your API Keys Secure: Never hard-code your API keys directly in your source code. Use environment variables or secure vaults to manage sensitive information.
  2. Error Handling: Implement robust error handling to manage API errors gracefully. Use try-catch blocks and provide meaningful error messages to users.
  3. Rate Limiting: Be mindful of API rate limits. Implement exponential backoff strategies for retrying failed requests.
  4. Logging: Use logging libraries to capture important events and errors. This will help you troubleshoot issues more effectively.
  5. Testing: Write unit tests for your code that interacts with the FinTag API. Use mocking libraries to simulate API responses.
  6. Documentation: Keep your code well-documented. Use comments and docstrings to explain complex logic and API interactions.
  7. Stay Updated: Regularly check for updates to the FinTag SDK and API. New features and bug fixes can enhance your application’s functionality and security.

​
Functions

The FinTag SDK provides a variety of functions to interact with the FinTag API. Here are some common functions you might use:
  • verify("#fintag"): Verifies a FinTag.
  • getWalletInfo("#fintag"): Retrieves wallet information for a specific FinTag.

​
Installation and Setup

Refer to the Installation Guide for detailed instructions on how to install and set up the FinTag SDK for your preferred programming language.

​
Example Usage

import { FintagClient } from '@fintag/js';

const fintag = new FintagClient({
    apiUrl: "<FINTAG_API_URL>",
    apiKey: "<FINTAG_API_KEY>"
});

// Function to Verify a FinTag
async function verifyFinTag(tag) {
    try {
        const result = await fintag.verify(tag);
        console.log('Verification Result:', result);
    } catch (error) {
        console.error('Error verifying tag:', error);
    }
}

// Function to Retrieve Wallet Info
async function retrieveWalletInfo(tag) {
    try {
        const walletInfo = await fintag.getWalletInfo(tag);
        console.log('Wallet Info:', walletInfo);
    } catch (error) {
        console.error('Error retrieving wallet info:', error);
    }
}


verifyFinTag('#fintag');
retrieveWalletInfo('#fintag');
