+
+### Fixed
+
+- **Docker Environment Support:** API Verification Secret now visible on customer licenses page in Docker environments
+  - Added `ResponseSigner::getServerSecret()` method to check multiple sources for server secret
+  - Checks PHP constant, `getenv()`, `$_ENV`, and `$_SERVER` in priority order
+  - Maintains full backward compatibility with standard WordPress installations
+
+### Changed
+
+- Updated `Plugin.php` to use `ResponseSigner::isSigningEnabled()` instead of direct constant check
+
+### Technical Details
+
+- Root cause: Docker WordPress setups using `wp-config-docker.php` with `getenv_docker()` don't always define PHP constants
+- The environment variable was accessible but the constant wasn't being created
+- New `getServerSecret()` method centralizes all server secret retrieval logic

+### 2026-02-01 - Bug Fix: API Verification Secret Not Visible
+
+**Overview:**
+
+Fixed the "API Verification Secret" (customer secret) not appearing on the customer account licenses page in Docker environments.
+
+**Root Cause:**
+
+The `WC_LICENSE_SERVER_SECRET` constant was not being defined even though the environment variable was set. In Docker WordPress setups using `wp-config-docker.php`, the `getenv_docker()` function retrieves values from environment variables, but the constant wasn't being created properly. The plugin was only checking for the PHP constant, not the environment variable directly.
+
+**Fix:**
+
+Added `ResponseSigner::getServerSecret()` static method that checks multiple sources for the server secret:
+
+1. `WC_LICENSE_SERVER_SECRET` constant (standard WordPress configuration)
+2. `getenv('WC_LICENSE_SERVER_SECRET')` (Docker environments)
+3. `$_ENV['WC_LICENSE_SERVER_SECRET']` (some PHP configurations)
+4. `$_SERVER['WC_LICENSE_SERVER_SECRET']` (fallback)
+
+**Modified files:**
+
+- `src/Api/ResponseSigner.php` - Added `getServerSecret()` method, updated `isSigningEnabled()` and `getCustomerSecretForLicense()` to use it
+- `src/Plugin.php` - Updated to use `ResponseSigner::isSigningEnabled()` instead of direct constant check
+
+**Technical notes:**
+
+- The fix maintains backward compatibility with standard WordPress installations using constants
+- Docker environments can now use environment variables directly without needing the constant to be defined
+- All three methods (`isSigningEnabled()`, `getCustomerSecretForLicense()`, and constructor) now use the centralized `getServerSecret()` method
