+# Saleor App Configuration
+# ========================
+
+# Required: Secret key for encrypting metadata (generate a random 32+ character string)
+# Used by EncryptedMetadataManager for securing app configuration data
+SECRET_KEY=your-secret-key-here-minimum-32-characters
+
+# APL (Auth Persistence Layer) Configuration
+# ==========================================
+
+# APL Type: Choose one of "file", "upstash", or "rest"
+# - "file": Single tenant, local development (default)
+# - "upstash": Multi-tenant, production ready
+# - "rest": Saleor Cloud APL
+APL=file
+
+# For APL type "rest" (Saleor Cloud):
+# REST_APL_ENDPOINT=https://your-saleor-cloud-instance.saleor.cloud/graphql/
+# REST_APL_TOKEN=your-saleor-cloud-token
+
+# For APL type "upstash":
+# UPSTASH_REDIS_REST_URL=your-upstash-redis-url
+# UPSTASH_REDIS_REST_TOKEN=your-upstash-redis-token
+
+# App URLs and Base Configuration
+# ===============================
+
+# Base URL for your app (used for manifest and webhooks)
+# In development, this is typically http://localhost:3000
+# In production, this should be your deployed app URL
+APP_BASE_URL=http://localhost:3000
+
+# Optional: Override iframe base URL (for embedded app interface)
+# If not set, uses APP_BASE_URL
+APP_IFRAME_BASE_URL=http://localhost:3000
+
+# Optional: Override API base URL (for webhooks and API endpoints)
+# If not set, uses APP_BASE_URL
+APP_API_BASE_URL=http://localhost:3000
+
+# Domain Security
+# ===============
+
+# Optional: Regex pattern to restrict which Saleor instances can install this app
+# Example: ".*\\.saleor\\.cloud$" to only allow Saleor Cloud instances
+# If not set, all domains are allowed
+ALLOWED_DOMAIN_PATTERN=
+
+# Server Configuration
+# ====================
+
+# Port for the development server (default: 3000)
+PORT=3000
+
+# Vercel deployment URL (automatically set by Vercel)
+# VERCEL_URL=https://your-app.vercel.app
+
+# Logging Configuration
+# ====================
+
+# Log level: debug, info, warn, error (default: info)
+APP_LOG_LEVEL=info
+
+# OpenTelemetry Configuration (optional)
+# =====================================
+
+# Enable OpenTelemetry logging (true/false)
+OTEL_ENABLED=false
+
+# Service name for OpenTelemetry
+OTEL_SERVICE_NAME=saleor-invoice-app
+
+# CI/CD Environment
+# =================
+
+# Set to "true" when running in CI/CD environment
+CI=false
+
+# File Storage Configuration
+# ==========================
+
+# Directory for temporary PDF storage (default: auto-generated temp directory)
+# Ensure this directory is writable by the application
+TEMP_PDF_STORAGE_DIR=
+
+# Saleor Cloud Migration Scripts (optional)
+# =========================================
+
+# Required for running migration scripts with Saleor Cloud APL
+# SALEOR_CLOUD_TOKEN=your-saleor-cloud-token
+# SALEOR_CLOUD_RESOURCE_URL=https://your-saleor-cloud-instance.saleor.cloud/graphql/
+
+# Development Notes:
+# ==================
+# 
+# 1. For local development, you only need:
+#    - SECRET_KEY (required)
+#    - APP_BASE_URL (optional, defaults to http://localhost:3000)
+#    - APL=file (default)
+#
+# 2. For production deployment:
+#    - Set APL to "upstash" or "rest"
+#    - Configure the corresponding APL environment variables
+#    - Set APP_BASE_URL to your production URL
+#    - Ensure SECRET_KEY is a strong, random string
+#
+# 3. For Saleor Cloud deployment:
+#    - Set APL=rest
+#    - Configure REST_APL_ENDPOINT and REST_APL_TOKEN
+#    - Set SALEOR_CLOUD_TOKEN and SALEOR_CLOUD_RESOURCE_URL for migrations
+#
+# 4. Security considerations:
+#    - Never commit SECRET_KEY to version control
+#    - Use strong, random values for all tokens
+#    - Restrict ALLOWED_DOMAIN_PATTERN in production
