T3Planet License Manager Activation: A Complete Step-by-Step Guide

Managing premium TYPO3 extensions across multiple projects often means juggling license emails, manual downloads, domain changes, and update requests, all outside your CMS. For agencies and developers handling more than one TYPO3 instance, this adds up fast.

T3Planet License Manager (EXT:ns_license) consolidates everything into a single backend module inside your TYPO3 instance. Trials, activations, renewals, domain transfers, and updates, all handled without a single support ticket.

This guide covers every step: getting your license key, activating via Extension Manager or Composer, managing domains, extending licenses, and staying up to date across projects.

Who this is for: TYPO3 developers, integrators, and agencies managing one or more T3Planet extensions or templates.

What Is T3Planet License Manager?

T3Planet License Manager is a TYPO3 backend module (EXT:ns_license) installed directly in your TYPO3 instance. It gives you centralized, self-service control over all T3Planet products, no external dashboards, no support dependency.

Trusted by 3,250+ TYPO3 customers and with 60,000+ EXT:ns_license downloads, T3Planet is one of the leading TYPO3 marketplaces for premium templates, extensions, and AI solutions.

With T3Planet License Manager, you can:

• Start 30-day free trials directly from your TYPO3 backend
• Activate license keys received after purchase or trial
• Extend license periods and manage renewals
• Assign and transfer licenses across domains
• Explore and access additional T3Planet products

The module supports the full T3Planet ecosystem, including AI Universe Solutions, TYPO3 templates, TYPO3 extensions, and TYPO3 Services.

How to Get a T3Planet License Key and Start a Free Trial

T3Planet provides two ways to obtain a license key: purchasing a product or starting a free trial. Both follow the same delivery process.

When you purchase a product or initiate a trial, a license key is generated and sent to your email.

This email includes:

• A unique license key for each product
• Composer credentials (for Composer-based installations, if applicable)

Store this email securely - you will need it to activate and manage the extension in your TYPO3 instance.

If the email does not arrive within a few minutes:

• Check your spam or filtered folders
• If still missing, request your license details via the T3Planet support portal

How to Activate T3Planet License in TYPO3 (Step-by-Step Guide)

Once you have your license key, activation can be completed using either the Extension Manager or Composer, depending on your TYPO3 setup.

Prerequisites before you begin:

• Compatible with TYPO3 v8 through v14
• Admin access to the TYPO3 backend
• Your license key from the T3Planet email

Method 1: Install via Extension Manager (Non-Composer)

Use this method if your TYPO3 instance is not Composer-based.

Step 1: Go to the Extension module → select Get Extensions → click Update Now to refresh the repository.

Step 2: Search for ns_license, then install the extension.

Step 3: Navigate to NITSAN > License Management → click Add License Key → paste your license key.

Step 4: Go to Admin Tools > Extensions, locate your extension, and activate it.

Method 2: Install via Composer (Recommended)

Use this method for all Composer-based TYPO3 installations. This approach supports CI/CD pipelines and multi-extension setups.

Step 1: Install License Manager EXT:ns_license

composer require nitsan/ns-license

vendor/bin/typo3 extension:setup

Step 2: Add License Key
Go to TYPO3 backend → License Manager → add your license key.

Step 3: Install Extension

composer config repositories.t3planet '{
  "type": "composer",
  "url": "https://composer.t3planet.cloud",
  "only": ["nitsan/<PACKAGE-NAME>"]
}'
composer config http-basic.composer.t3planet.cloud <USERNAME> <LICENSE-KEY>
composer req nitsan/<PACKAGE-NAME> --with-all-dependencies
vendor/bin/typo3 extension:setup

For advanced Composer configuration (private repository setup, multiple extensions, CI/CD), refer to the dedicated Composer guide.

Installing Multiple Extensions via Composer

To install multiple premium extensions in a single TYPO3 instance, T3Planet provides multiple Composer repositories.

• Repository pattern: https:// composer(n).t3planet.cloud (where n = 1 to 99)
• Each extension gets its own numbered repository. Here's an example for the first extension:

composer config repositories.t3planet1 '{
"type": "composer",
"url": "https://composer1.t3planet.cloud",
"only": ["nitsan/ns-t3ac", "nitsan/ns-t3cs"]
}'
composer config http-basic.composer1.t3planet.cloud <USERNAME> <LICENSE-KEY>
composer req nitsan/<PACKAGE-NAME> --with-all-dependencies
vendor/bin/typo3 extension:setup

Repeat this process for each additional extension, incrementing n by 1 each time (composer2, composer3, and so on).

Migrating from Free Trial to Premium License

If you are upgrading from a trial to a paid license, no reinstallation is needed:

Step 1: Go to License Manager

Step 2: Deactivate and remove the trial license key

Step 3: Enter your new premium license key (received via email)

Step 4: Go to Extension Manager and activate the extension again

Important Operational Notes:

• License keys and Composer credentials are sent via email at the time of purchase or trial
• If credentials are missing, request them via the T3Planet support portal
• Some extensions (e.g., TYPO3 AI search/chatbot, Slider Revolution) may require additional setup commands depending on the TYPO3 version

How to Extend or Renew Trial Your T3Planet License in TYPO3

When your trial period ends or your license is due for renewal, you can extend it directly from the T3Planet License Manager.

Extend License Period

Use this when renewing an active license.

Step 1: Go to NITSAN > License Management in your TYPO3 backend

Step 2: Locate the product and click Extend License

Step 3: Complete the renewal process

The updated license is applied immediately. No reinstallation or configuration changes are required.

Transferring a License to Another Domain

Licenses are tied to one active domain but can be reassigned when needed.

This is useful when:

• Migrating a TYPO3 project to a new server
• Moving to a new domain
• Reassigning a license to another TYPO3 instance

To transfer a license:

Step 1: On the current TYPO3 instance, go to NITSAN > License Management

Step 2: Click Deactivate License for the relevant product

Step 3: Go to Admin Tools > Extensions and deactivate the extension

Step 4: On the new TYPO3 instance, install EXT:ns_license, add your license key, and activate the extension

Once completed, the license is active on the new domain. The previous domain is automatically released.

Managing License Domains and Logs in T3Planet License Manager

To transfer a license, follow the deactivation and reactivation process described earlier in this guide.

Viewing License Logs

The License Manager includes a Logs view that provides visibility into license activity.

It records:

• License activations
• License deactivations
• Domain usage history

This is particularly useful for agencies managing multiple TYPO3 instances, you can track exactly where and when each license has been used, making audits and migrations significantly easier.

What Happens with Unauthorized License Keys or Domains?

The T3Planet License Manager is designed to keep your TYPO3 backend clear and transparent, especially when there is an issue with a license. Instead of failing silently, it provides clear visual signals when a license key is unauthorized, expired, or used on a domain outside its permitted scope.

When an extension is running with an invalid or unauthorized license, its functionality is intentionally restricted. This helps ensure proper licensing compliance while making the issue immediately visible to administrators.

Key Indicators of a License Issue

You may notice the following changes in your TYPO3 backend:

• Extension labels or interface elements may be missing
• Certain features or content areas may stop working as expected
• Backend structures may appear incomplete or inconsistent

These are not random errors, but controlled indicators that the license is either expired, misconfigured, or assigned to a different domain.

Technical Perspective

• From a technical standpoint, this behavior is implemented through a fallback mechanism in the localisation (locallang) files.
• When the license is not valid, the extension labels are removed or replaced with minimal placeholders.
• This ensures that the extension remains structurally present while clearly indicating restricted usage due to an invalid or expired license.

Important Note:
Once a license expires or becomes unauthorized, the extension will no longer be fully usable.

To restore full functionality, you must renew the license or assign it correctly to the intended domain. Once a valid license is in place, all features are restored instantly without requiring additional configuration.

How to Resolve License Issue

Step 1 - Verify the assigned domain

Confirm the license is assigned to the correct domain under NITSAN > License Management. A mismatch here is the most common cause.

Step 2 - Use Renew or Repair

The License Manager provides both a Renew option for expired licenses and a Repair option for misconfigured ones. Both are available directly from the module, no support ticket required.

Note: The Repair option is enabled only when the license key is active, extended, or purchased.

Step 3 - Confirm the license is active

Check that the license status shows as active and that the expiry date is current. If the license has lapsed, renewal applies immediately with no reinstallation required.

Trial Extensions

If the issue is tied to an expired free trial, a one-time 15-day extension is available directly from the License Manager. This gives you additional time to evaluate the extension before committing to a purchase.

After the extension period, a valid license purchase is required to continue using the product. Purchasing restores full functionality instantly, no configuration changes needed.

How to Update T3Planet Extensions in TYPO3 (Backend & Composer)

Keeping your T3Planet extensions updated ensures compatibility, security, and access to new features.

Before any major update: Take a full backup (code and database), ensure EXT:ns_license is up to date, and verify compatibility with your TYPO3 version. Skipping this step increases rollback risk.

Method 1: Check for Updates via TYPO3 Backend

You can manually check for updates directly in TYPO3:

Step 1: Go to NITSAN > License Management

Step 2: Click Get Updates

Step 3: If a new version is available, click Update to x.x.x

T3Planet also sends email notifications when new versions are released - so you never miss an update.

Method 2: Update via Composer (Recommended)

For Composer-based TYPO3 installations, updates are handled through standard Composer workflows:

composer update nitsan/<PACKAGE-NAME>
composer dump-autoload
vendor/bin/typo3 cache:flush

This approach integrates with CI/CD pipelines, where updates can be applied during deployment.

Additional Notes

• Composer updates can be integrated into CI/CD workflows
• Some extensions may require additional setup after updates
• Refer to official documentation for extension-specific instructions

Migration guide: Migration To New Composer — T3Planet Docs 1.0 documentation

Refer to the official documentation for exact commands and paths.

Migration Guide: Upgrade to T3Planet License System in TYPO3

Who this section is for: Existing T3Planet customers using older extensions installed before the current license system. If you installed your extensions recently, skip this section, you're already on the licensed system.

If your extensions were installed before the license system was introduced, migration is required to enable license validation, automatic updates, and domain management going forward.

Before You Start

• Take a full backup of your TYPO3 instance (code and database)
• Ensure you have your license key (sent via email)

Skipping backup introduces rollback risk if migration fails.

Method 1: Migration for Non-Composer TYPO3

Step 1: Go to Admin Tools > Extensions → deactivate the existing extension

Step 2: Delete the extension from the Extension Manager

Step 3: Reinstall the extension using the License Manager workflow (as covered above)

Method 2: Migration for Composer-Based TYPO3

Step 1: Remove old extension

composer remove nitsan/<EXTENSION-NAME>
composer dump-autoload
composer clear-cache

Step 2: Remove legacy files

rm -rf typo3conf/ext/<extension_key>

Not sure of the extension key? Check your typo3conf/ext/ directory or the extension's ext_emconf.php file.

Step 3: Reinstall using licensed Composer setup

Follow the Composer installation steps described earlier in this guide. Your license key will be used as the Composer credential for the private T3Planet repository.

Important Notes

• Some extensions (e.g., Slider Revolution) may require additional migration steps
• Legacy installations may contain custom modifications that are not preserved
• Migration does not guarantee backward compatibility with older TYPO3 versions
