Implementation Guide

Setting a Metered License

Implementing a metered license is crucial for tracking usage. Here’s how:

Overview

A metered license allows developers to track document processing operations, helping manage costs effectively.

Step-by-Step Implementation

1. Create an Instance of Metered Start by creating a Metered object to manage your licensing keys.

// Feature: Set Metered License
using System;
using GroupDocs.Signature;

namespace GroupDocsSignatureExamples
{
    class SetMeteredLicenseExample
    {
        public static void Run()
        {
            // Create an instance of Metered
            Metered metered = new Metered();

2. Define Your License Keys Replace placeholders with your actual license keys.

            // Define your license keys (placeholders for demonstration)
            string publicKey = "*****";
            string privateKey = "*****";

3. Set the Metered License Key Apply your public and private keys to set up metering.

            // Set the metered license key with provided public and private keys
            metered.SetMeteredKey(publicKey, privateKey);
        }
    }
}

Explanation

  • Metered Class: Manages usage tracking of your application.
  • Keys: publicKey and privateKey are essential for setting up a secure metering system.

Troubleshooting Tips

If you encounter issues, ensure:

  • Keys are correctly entered without typos.
  • Your GroupDocs.Signature library is up-to-date.
  • Check network permissions if keys are fetched from a remote server.

Practical Applications

Here are some scenarios where setting a metered license proves beneficial:

  1. Usage Analytics: Track document processing to help with resource allocation and cost management.
  2. Subscription Models: For SaaS applications offering document signing, metering helps tailor subscription plans based on user activity.
  3. Audit Compliance: Maintain records of document handling for compliance with standards like GDPR or HIPAA.

Performance Considerations

Optimizing performance using GroupDocs.Signature involves:

  • Efficient Memory Management: Dispose of Signature objects properly to free up resources.
  • Resource Usage Guidelines: Monitor CPU and memory usage, especially when processing large documents.
  • Best Practices:
    • Use asynchronous operations where possible.
    • Cache repeated license verification results if they don’t change often.

Conclusion

Implementing a metered license with GroupDocs.Signature for .NET is straightforward once you understand the setup process. This feature not only helps in tracking usage but also ensures your application remains cost-effective and compliant with licensing requirements.
