API Meter Learning Center

Master modern API orchestration. Move beyond linear request chaining and embrace a visual, clarity-first approach to API testing.

The API Meter Philosophy

Tools like Postman were built for a different era. API Meter mimics the power of established tools but introduces a revolutionary Visual Workflow Canvas, context-aware Variables, and instant Version Control.

Quick Start

Send your first request in seconds. No setup required.

  1. Create a Workspace

    Upon logging in, you start in your 'Personal' workspace. This is your sandbox.

  2. Create a Collection

    Click the + button in the sidebar. Name it "Demo API". This acts as your folder root.

  3. Add a Request

    Hover over your collection, click ... → Add Request. Enter a URL (e.g., https://api.public.com/users).

  4. Send

    Hit the white Send button. Inspect the status code and JSON response in the panel below.

Vs Postman

Why developers are switching to API Meter.

Feature API Meter Legacy Tools
Workflows Visual Canvas (Drag & Drop) Scripted / Linear
Data Passing Auto-extracted Manual Scripts
Versioning Native Snapshots Duplicating requests
Performance Instant Load Heavy

Collections & Folders

Collections organize your requests. They define the structure of your project and can hold shared authentication settings.

Recommended Structure

📦 My E-Commerce API
 ┣ 📂 Users
 ┃ ┣ 📄 Get All Users
 ┃ ┣ 📄 Create User
 ┃ ┗ 📄 Login
 ┣ 📂 Products
 ┃ ┣ 📄 Search Products
 ┃ ┗ 📄 Get Inventory

Importing Data

Switching from Postman? Click Import in the sidebar, upload your Collection JSON, and we'll migrate your folders, requests, and scripts instantly.

Building Requests

The Request Builder is the heart of API Meter. It supports all standard HTTP methods (GET, POST, PUT, DELETE, PATCH).

Headers & Parameters

Use the grid editor to manage Query Params and Headers. Toggle items on/off without deleting them to test different scenarios.

Body Editor

We support multiple body types with full syntax highlighting:

  • JSON: Auto-formatted with error detection.
  • Form Data: For multipart file uploads.
  • x-www-form-urlencoded: Key-value pairs.

Authentication

Never hardcode tokens. Use the Auth tab for secure credential management.

Best Practice Use "Inherit from Parent" auth on your requests. Set the Bearer Token once on the Collection level, and all requests inside will automatically use it.

Variables & Scope

Stop copy-pasting ID strings. Use variables. Reference them anywhere using double curly braces: {{user_id}}.

Smart Autocomplete

Type {{ in any field (URL, Headers, Body) to see a dropdown of all available variables and their current resolved values.

Scope Priority

  1. Workflow Variables (Highest)

    Dynamic data passed from a previous node in a visual workflow.

  2. Environment Variables

    Context-specific values (e.g., base_url changes between Staging and Prod).

  3. Global Variables (Lowest)

    Constants available across the entire workspace.

Visual Workflows Coming Soon

Orchestrate complex sequences visually. No hidden scripts. No invisible dependencies.

In Development

We are actively building a revolutionary node-based canvas for API chaining. You will be able to drag, drop, and wire requests together to pass data automatically.

Capacity Testing Coming Soon

Native load testing to ensure your API handles scale.

In Development

Simulate virtual users and measure throughput directly from the API Meter interface.

Collection Runner

Testing a full sequence? The Collection Runner executes every request in a folder in order.

  • Iterations: Upload a CSV/JSON file to run the collection once for each row of data.
  • Delays: Add pauses between requests to avoid rate limits.
  • Data Persistence: Toggle whether variables are updated during the run.

Scripting Engine

For power users, API Meter exposes a full JavaScript runtime. Use simpler syntax than you're used to.

  • Pre-request Scripts: Run JS before a request is sent (e.g. generate timestamps).
  • Tests: Write assertions on the response.
// Set a variable
pm.environment.set("token", "12345");

// Test response
pm.test("Status is 200", function () {
  pm.response.to.have.status(200);
});

History

Your "Time Machine" for requests. Every request sent is auto-saved in the History tab. Click any entry to instantly restore the editor to that exact state.

Versioning & Comparison

API Meter treats requests like code. You can save named snapshots of a request to safely experiment without losing working configurations.

Creating Versions

Click the Save Version icon in the header. Name it (e.g., "v1.0 Stable"). You can now modify the request freely. If you break it, just switch back to "v1.0 Stable" from the dropdown.

Side-by-Side Comparison

Unsure what changed between "v1.0" and "v2.0"? Open the Diff View. We visually highlight changes in:

  • Method & URL
  • Headers (Added/Removed/Modified)
  • JSON Body (Line-by-line diff)

Collaboration

Work together without the friction.

Sharing Collections

Click the Share icon on any collection to generate a link or invite team members directly.

Export Documentation

Turn your collection into a read-only website similar to this one. Great for public APIs.

Smart Bot Bypass

Use our advanced header emulation to test APIs protected by strict WAFs or bot detection filters (like Cloudflare).

How to Use

  1. Select Headers

    In the request builder, ensure your User-Agent and other browser-like headers are configured.

  2. Automatic Emulation

    API Meter automatically attempts to structure the request fingerprint to mimic a legitimate browser interaction, helping you bypass standard bot blocks during testing.

Export & Reporting

Generate detailed test reports for compliance and stakeholder sharing.

Generating Reports

  1. Run Collection

    Use the Collection Runner to execute your test suite.

  2. View Summary

    Once the run is complete, you will see a detailed summary of passed/failed tests.

  3. Export

    Click the Export PDF or Export Excel buttons in the top right of the runner results to download a professional report.

Move Collections

Easily reorganize your work across different workspaces.

Steps

  1. Context Menu

    Right-click (or click the ... menu) on any Collection in the sidebar.

  2. Select Move

    Choose Move to Workspace from the dropdown menu.

  3. Choose Destination

    Select the target workspace from the list. Your collection, including all requests and history, will be transferred instantly.

Feature Guards

Manage access to experimental functionality.

Configuration

Admins can toggle beta features in Workspace Settings > Features to maintain team stability.

Team & Workspace Management

Scale your API development with enterprise-grade collaboration features.

Role-Based Access Control (RBAC)

Assign granular permissions to team members to secure your workspace:

  • Admin: Full access to manage members and workspace settings.
  • Editor: Can create, edit, and delete collections and requests.
  • Viewer: Read-only access to view documentation and run requests.

Member Invitations

Invite colleagues directly from the "Workspace Settings" dialog. Invitations are delivered as in-app notifications, allowing you to manage pending invites and revoke access instantly when needed.

Trash & Recovery

Safety net for your data. Never lose work accidentally.

Restore Deleted Items

Deleted collections and requests are moved to the Trash Bin instead of being permanently erased. You can view deleted items and restore them to their original location with a single click.

Intelligent Code Editor

A powerful, VS Code-like editing experience built directly into API Meter.

Features

  • JSON Key Suggestions: Get context-aware autocomplete for common API keys and values while typing in the body editor.
  • Smart Variable Autocomplete: Type {{ to instantly see a dropdown of all available environment and global variables.
  • Syntax Highlighting: Full color-coding for JSON, XML, JavaScript, and more.

Security Architecture

API Meter is built with a security-first approach, ensuring your data and tokens remain safe using enterprise capabilities.

Data Encryption

All sensitive variables and tokens are encrypted at rest using AES-256-GCM. We utilize a secure Vault architecture to ensure that keys are never exposed in plain text logs or database dumps.

Sandboxed Execution

The Scripting Engine runs in an isolated V8 context, preventing any malicious code from accessing your local file system or network outside of the intended request scope.

Compliance API Meter is designed to be SOC2 compliant ready, with comprehensive audit logging and role-based access control (RBAC).
