How to use this tool to generate JSON-RPC messages.

1. Select Version and Type: Choose between JSON-RPC 1.0 and 2.0, and select the message type you want to generate.
2. Configure Parameters: Fill in the form with the parameters for your message such as method name, params, result, or error details.
3. Generate Message: Click the generate button to create your message. The result will appear in the JSON editor.
4. Copy or Modify: Copy the generated JSON or modify it directly in the editor. You can also use templates as starting points.
Batch Mode: Enable batch mode to generate multiple requests or responses in a single JSON array. This is useful for testing batch processing capabilities of JSON-RPC servers.

What's the difference between JSON-RPC 1.0 and 2.0?: JSON-RPC 2.0 adds the 'jsonrpc: "2.0"' version identifier, supports named parameters (objects) and positional parameters (arrays), includes notification messages (no ID), and has standardized error objects with reserved error codes.
What is a notification in JSON-RPC?: A notification is a request without an ID field, indicating that no response is expected. It's only available in JSON-RPC 2.0 and is useful for one-way messaging.
Can I have both 'result' and 'error' in a response?: No, a JSON-RPC response must contain either a 'result' field or an 'error' field, but never both. If the request succeeded, include 'result'; if it failed, include 'error'.
What should I use for the ID field?: The ID can be a string, number, or null. It's used to match responses to requests. For error responses regarding invalid JSON, use null. Otherwise, use the same ID that was in the request.
What are batch requests?: Batch requests allow sending multiple JSON-RPC calls in a single request by wrapping them in a JSON array. The server responds with an array of responses in the same order.
