Mikrotik Api V3 ((top)) Page

The release of RouterOS v7 marked a turning point for MikroTik management, introducing the highly anticipated REST API as a modern alternative to the legacy proprietary API. While "API V3" is often used informally to refer to the latest generation of programmatic access in the v7 ecosystem—or to recent updates like WinBox v3/v4 —the most significant shift for developers is the transition from binary-based socket communication to JSON-over-HTTPS . The Evolution of MikroTik Programmatic Access For years, developers relied on the legacy MikroTik API , which used a custom "word-based" protocol over ports 8728 (plain) and 8729 (SSL). While efficient, it required specialized libraries and complex parsing. With the REST API, MikroTik has aligned with industry standards, offering: JSON Payloads : Results are returned in standard JSON, eliminating the need for custom translation layers. HTTP Methods : Uses standard GET , POST , PATCH , and DELETE for CRUD (Create, Read, Update, Delete) operations. Statelessness : No need to maintain a persistent socket connection, making it ideal for web-based automation. Key Features and Capabilities The modern API interface in RouterOS v7 provides a direct wrapper around the console commands. Legacy API (v1/v2) Modern REST API (RouterOS v7+) Protocol Proprietary Byte-length based HTTPS / JSON Port 8728 (Plain), 8729 (SSL) 80 (HTTP), 443 (HTTPS) Ease of Use Requires specialized wrappers Works with cURL , Postman , or any HTTP client Data Format Custom binary words Standard JSON How to Get Started To use the modern RESTful interface, you must first enable the www or www-ssl service on your router. Enable the Service : Run /ip service enable www-ssl . Basic Request : Use a tool like cURL to query router information: curl -k -u admin:password https://192.168.88 Use code with caution. Schema Integration : Developers can now import REST API schemas into tools like Postman or generate OpenAPI documentation for automated testing. Why This Matters for Network Automation The shift toward standardized web technologies allows for easier integration with third-party platforms. Systems like Grafana for visualization or Ansible for configuration management can now interact with MikroTik devices more natively. While the legacy API remains available for high-speed, real-time monitoring where low overhead is critical, the REST API is the clear choice for modern, scalable cloud and web integrations. Are you looking to migrate an existing script from the legacy API to REST, or are you starting a new automation project from scratch? REST API - RouterOS - MikroTik Documentation

While MikroTik has not officially designated a "Version 3" for its native API protocol, the introduced in RouterOS v7 represents the most modern evolution of their programmatic interface. If you are looking for a "headline" feature for an article or project, the best choice is the Native JSON Support within the REST API. Top Feature: Native JSON Support This feature fundamentally changes how developers interact with MikroTik routers compared to the legacy binary API. No Custom Libraries Needed : Unlike the legacy API which requires specific libraries to parse raw bytes, the REST API works with standard HTTP requests using tools like Front-End Friendly : Since the router now returns data in structured , it can be consumed directly by web dashboards, mobile apps, or JavaScript frameworks without intermediate "translation" code. Standard Web Methods : It utilizes familiar HTTP verbs— —to manage router resources like firewall rules, IP addresses, and interfaces. Practical Implementation Idea You could frame your feature around "Real-time Monitoring without the Overhead." Using the REST API, you can easily pull real-time bandwidth data from /interface/monitor-traffic and feed it into modern visualization tools like ESP32-based displays Postman guide to help you test this new API?

Mastering MikroTik API V3: The Ultimate Guide to Automation In the modern world of network administration, the Graphical User Interface (GUI) is no longer enough. As networks grow to dozens or hundreds of routers, manual configuration becomes a bottleneck. Enter MikroTik API V3 . While many administrators are comfortable using WinBox or SSH, the API (Application Programming Interface) unlocks the true potential of RouterOS. It allows you to integrate your MikroTik devices into custom dashboards, billing systems, provisioning scripts, and DevOps pipelines. This article is a deep dive into MikroTik API V3. We will cover what changed from Version 2, how to connect, authentication flows, command execution, scripting examples in Python and PHP, and advanced error handling. Part 1: API V2 vs. API V3 – What Changed? Before diving into code, it is critical to understand that MikroTik API V3 is not just a minor update; it is a significant architectural shift. API V1/V2 (Legacy)

Transport: Plain TCP (Port 8728) or SSL (Port 8729). Grammar: Simple sentence structure ( /interface/print ). Limitations: No multiplexing. You send a command, wait for the reply, send the next. Slow for large datasets. Mikrotik Api V3

API V3 (Current Standard)

Transport: Uses the same port structure (8728 for non-TLS, 8729 for TLS), but introduces sessions . Key Feature: Query Optimization. V3 allows server-side filtering. Instead of downloading 10,000 firewall rules to your script and filtering locally, V3 asks the router to filter before sending. Reply Format: Uses !re (Reply) and !done markers with better data typing.

Transition Note: If you are using scripts written before 2017, they likely target V2. While RouterOS still accepts legacy commands, V3 is more efficient and should be your default. Part 2: How the MikroTik API V3 Works The API V3 is a synchronous, text-based protocol over TCP. Every interaction follows a strict pattern: The release of RouterOS v7 marked a turning

Connect: Client connects to port 8728 (or 8729 for SSL). Login: Client sends /login command. Challenge (Security): Router responds with a ret key (usually ae2 for newer versions). Client computes a MD5 challenge response. Command Loop: Client sends words (parameters), terminated by an empty line. Router responds with !re (data rows) and finally !done . Logout/Close: Closing the socket.

The "Sentence" Structure Unlike REST APIs (JSON over HTTP), MikroTik uses a custom framing.

A command word starts with a slash: /ip/address/print Parameters: =.id=*1 or =address=192.168.1.1 Query tags: ? (e.g., ?disabled=no ) Proplist: .proplist=address,network Statelessness : No need to maintain a persistent

Part 3: Authentication Deep Dive – The MD5 Challenge Authentication is the most confusing part for newcomers. MikroTik does not send passwords in plain text (if done correctly). Here is the V3 flow:

Client: :delay 1 followed by /login Router: !done ret=ae2d10a5c58da584e51e3a0d3e86210a Client: Computes MD5( "ae2d10a5c58da584e51e3a0d3e86210a" + "plaintext_password" ) Client: Sends /login with =name=admin =response=hex_digest Router: !done (Success) or !trap (Failure)
