|
|
|
|
### Permission Handling
|
|
- Runtime permission requests with proper handling
|
|
- Graceful degradation saat permission ditolak
|
|
- User-friendly error messages
|
|
|
|
### Network Security
|
|
- HTTPS endpoint untuk webhook
|
|
- Timeout handling (10 seconds)
|
|
- Content-Length header validation
|
|
|
