🔐 Security Notes

API Keys

Never commit API keys to version control!

# Add to .gitignore
echo "local.properties" >> .gitignore
echo ".env" >> .gitignore
echo "*.properties" >> .gitignore

Use environment variables or build configuration:

Android (build.gradle.kts):

android {
    defaultConfig {
        val apiKey = project.findProperty("notap.api.key") as String? ?: ""
        buildConfigField("String", "NOTAP_API_KEY", "\"$apiKey\"")
    }
}

Web (.env):

NOTAP_API_KEY=your_key_here

---

🐛 Troubleshooting

"API key not found"

Solution: Create local.properties (Android) or .env (Web) with your API key.

"Module not found" (Web)

Solution:

rm -rf node_modules package-lock.json
npm install

"SDK version mismatch" (Android)

Solution: Update dependencies in build.gradle.kts:

implementation("com.zeropay:sdk:1.0.0")
