Scheduling & Timezone Management

Introduction

All Lovi notification endpoints support scheduling for future delivery. This feature allows you to send notifications at optimal times considering recipient timezones and business hours.

📅 Scheduling Parameters

Both WhatsApp and Voice notifications support the following scheduling parameters:

Parameters

Parameter	Type	Required	Description	Example
`datetime_sending`	DateTime	No	Scheduled date/time in ISO 8601 format	`"2024-12-25T10:30:00"`
`timezone`	String	No	Timezone for the scheduled time	`"Europe/Madrid"`

Default Behavior: If datetime_sending is not provided, the notification is sent immediately.

🕐 Datetime Format

Supported ISO 8601 Formats

{
  "datetime_sending": "2024-12-25T10:30:00",
  "timezone": "Europe/Madrid"

⚙️ Validation Rules

Date Validation

✅ Future dates only: Must be later than current time
✅ Maximum advance: Up to 1 year in advance
✅ Format strict: Must follow ISO 8601
❌ Past dates: Will be rejected
❌ Invalid format: Non-ISO dates rejected

Timezone Validation

✅ Valid IANA codes: Use standard timezone database
✅ Case sensitive: Exact format required
❌ Abbreviations: Don’t use CET, EST, etc.
❌ Invalid codes: Unknown timezones rejected

Examples of Valid/Invalid

✅ Valid:

{
  "datetime_sending": "2024-12-25T14:30:00",
  "timezone": "America/Mexico_City"
}

❌ Invalid datetime:

{
  "datetime_sending": "12/25/2024 2:30 PM",  // Wrong format
  "timezone": "Europe/Madrid"
}

❌ Invalid timezone:

{
  "datetime_sending": "2024-12-25T14:30:00",
  "timezone": "CET"  // Use Europe/Madrid instead
}

🚀 Best Practices

Optimal Timing

WhatsApp Messages:

Business hours: 9:00 AM - 6:00 PM local time
Avoid early/late: Not before 8:00 AM or after 9:00 PM
Weekend consideration: Adjust for weekend preferences
Holiday awareness: Check local holidays

Voice Calls:

Business hours only: 9:00 AM - 5:00 PM local time
Workdays preferred: Monday through Friday
Lunch hours: Avoid 12:00 PM - 2:00 PM
Cultural sensitivity: Respect local customs

Timezone Strategy

Store user timezones: Save preferred timezone per contact
Local time display: Show times in user’s local timezone
Business hour logic: Calculate optimal sending times
Daylight saving: IANA codes handle DST automatically

🛠️ Development Tips

Testing Scheduling

Use near future: Test with times 5-10 minutes ahead
Timezone testing: Test different timezone scenarios
Edge cases: Test daylight saving transitions
Error handling: Test with invalid dates/timezones

Production Considerations

Buffer time: Add 2-3 minutes buffer for processing
Monitoring: Monitor scheduled vs actual send times
Retry logic: Handle temporary failures gracefully
Logs: Log scheduling details for debugging

Timezone Resources

IANA Database: Official timezone database
Online converter: Use tools to verify timezone codes
Documentation: Keep timezone reference for developers
