Hap 5.1: Authorization Code

The HAP 5.1 Authorization Code refers to a security credential used within systems following the HAP (Home Automation Protocol) version 5.1 specification. It is typically a temporary, single-use code issued by an authorization server to a client application, allowing the client to obtain an access token for accessing protected resources (e.g., smart home devices, user data).

A claim denial related to this authorization policy usually stems from one of three scenarios:

2.1 The Static Setup Code (Legacy but supported)

2.2 The Dynamic Authorization Token (New in HAP 5.1)

The authorization code in the HAP 5.1 specification is technically the "Setup Code" that, when combined with the accessory’s AccessoryPairingID, derives the Pre-shared Key for SRP authentication.


The HAP 5.1 authorization code in libraries like hap-python is stored in the config.json file:


  "pin": "111-22-333",
  "authorizationCode": "f7d3a1e8b9c2468d5f0e3a7b1c9d4e2f",
  "version": "5.1"

Important: Never commit your actual authorizationCode to GitHub. Use environment variables.


The Carrier Hourly Analysis Program (HAP) 5.1 is a leading software tool used globally by HVAC professionals, consulting engineers, and design-build contractors. It streamlines the complex tasks of estimating cooling and heating loads, sizing HVAC systems, and calculating hour-by-hour energy simulations for commercial buildings.

To unlock the full design and simulation suite of HAP 5.1, the software requires a specific Carrier HAP License Activation Code. 1. What is the HAP 5.1 Authorization Code?

The authorization code is an encrypted, alphanumeric key issued directly by Carrier to verify that your organization holds a valid license for the software.

How it functions: The authorization code binds the software installation to your specific organization name and unique customer number.

When it is required: You must input this code during the initial installation or when extending an expiring license. hap 5.1 authorization code

Multi-user configurations: A single license can often support up to 10 distinct users within the same company network. 2. Step-by-Step Activation Process

To successfully activate your software, follow these core steps provided by the Carrier eDesign Software installation guide:

[ Download & Run Installer ] ➔ [ Install XBuilder Framework ] ➔ [ Enter License Details ] ➔ [ Finalize Activation ] Step 1: Install the XBuilder Framework

Before installing HAP 5.1, you must deploy Carrier’s underlying operational framework, known as the XBuilder Framework. Open the extracted setup directory. Double-click the eCat / XBuilder installation file.

Follow the wizard prompts to select your geographic region and target folder (typically C:\). Step 2: Install Carrier HAP 5.1 Run the E20-HAP executable file from your setup package.

Proceed through the standard installation steps to copy the software files to your drive. Step 3: Input Authorization Information Launch the application from your Start Menu.

When the activation dialogue box appears, input the following exact details provided in your Carrier license e-mail:

Company Name: Must match the exact capitalization and punctuation used in the Carrier documentation. Customer Number: A designated 3-digit or 4-digit code.

Authorization Code: The exact alphanumeric string (e.g., 880B-XXXX-XXXX-XXXX).

Click OK. The software is immediately unlocked and ready for use. 3. Resolving Common Activation Errors

Activation can fail due to string mismatches or regional restrictions. Use this troubleshooting guide to resolve activation issues: Issue / Error Message Probable Cause Actionable Solution "Invalid Authorization Code" Mismatch in the registered company name or letter casing. The HAP 5

Copy and paste the company name and code directly from the Carrier e-mail. Do not manually type it out. "Code Expired" The trial or subscription period has lapsed.

Contact your local Carrier supplier to renew the license and request a new code. "Framework Error" The XBuilder framework was not installed prior to HAP.

Uninstall HAP completely, install the XBuilder Framework first, and then reinstall HAP. 4. Legitimate vs. Unofficial Software Use

Due to the commercial value of Carrier HAP 5.1, cracked versions and unofficial key generators ("keygen" files) often circulate in the engineering community. However, relying on unlicensed software exposes engineers to substantial risks:
