How to Get API Keys and Authenticate Requests with Symmetry Tax Engine

Introduction

This guide provides detailed instructions for obtaining API keys and authenticating requests when integrating with the Symmetry Tax Engine. Proper authentication is essential to securely access payroll tax calculation APIs and ensure reliable data exchange within your payroll or HR platform.

Generating API Keys

API keys are generated through your Symmetry account dashboard. Follow these steps to obtain your API key:

1. Log in to your Symmetry account dashboard at [Insert dashboard URL].
2. Navigate to the "API Keys" or "Developer Settings" section.
3. Click "Generate New API Key" and provide a descriptive name for the key to identify its usage.
4. Copy the generated API key and store it securely; you will not be able to view it again from the dashboard.
5. Configure any necessary permissions or scopes for the API key according to your integration needs.

Authenticating API Requests

To authenticate your API requests, include your API key in the HTTP Authorization header of each request as follows:

Authorization: Bearer {YOUR_API_KEY}

Replace {YOUR_API_KEY} with the actual API key obtained from your dashboard.

Make sure that all requests adhere to the current API version and endpoint specifications as provided in the official Symmetry API documentation.

Security Best Practices

To maintain strong security for your integration, follow these best practices:

• Store authentication tokens securely; avoid embedding keys in client-side code or publicly accessible areas.
• Regularly rotate API keys by generating new keys and revoking old ones according to your organization's security policies.
• Monitor API usage regularly via your account dashboard to detect any unauthorized access or abnormal activity.
• Use encrypted connections (HTTPS) for all API communications to protect data in transit.

Troubleshooting Authentication Issues

If you encounter authentication errors such as 400 Bad Request, 401 Unauthorized, or 403 Forbidden responses, verify the following:

• Ensure the API key is included correctly in the Authorization header with the 'Bearer' scheme.
• Confirm the API key has not expired or been revoked in your account dashboard.
• Check that you are targeting the correct API environment (sandbox or production) and base URL.
• Make sure your account has the necessary permissions associated with the API key for the requested operations.
