Implementation Guide

Setting a Metered License

A metered license tracks and manages GroupDocs.Annotation usage. Here’s how to configure it:

Overview:

Setting a metered license involves initializing the Metered class with your public and private keys for authentication.

Step 1: Initialize the Metered Object

using System;
using GroupDocs.Annotation.License;

namespace DocumentAnnotationApp {
    class Program {
        static void Main(string[] args) {
            // Initialize the Metered object
            Metered metered = new Metered();
        }
    }
}

Step 2: Define Your Keys

Replace placeholders with your actual keys:

string publicKey = "*****"; // Replace ***** with your actual public key
string privateKey = "*****"; // Replace ***** with your actual private key

Step 3: Set the Metered License

Use your keys to set up the license:

metered.SetMeteredKey(publicKey, privateKey);

Explanation: This authenticates your application using GroupDocs’ licensing server.

Troubleshooting Tips:

  • Ensure correct public and private keys.
  • Verify internet connectivity for license verification.
  • Refer to the API documentation for error resolution.
