Message

This is where you say what matters—the actual content your users need to see. Whether it’s an alert, a reminder, or a funny status update, the message field is what grabs attention.

• No strict length limit (but practical limits apply for readability).

• Supports line breaks for better formatting.

• Works with emojis because everything is better with emojis. 😎

• Plain text only—no markdown, HTML, or rich formatting.

Use Cases

The message can be used in many ways, from simple alerts to detailed reports. Here are some good examples:

Good Use Cases

✅ System Alerts: "Server CPU at 95%! Check logs now." ✅ Reminders: "Water the plants today!" ✅ Status Updates: "Your order #12345 has shipped!" ✅ Error Notifications: "❌ Backup failed! Check /logs for details."

Bad Use Cases

❌ Sending entire log files. ("Error 404. Error 405. Error 406. Error..." 😵) ❌ Writing an essay. (Nobody reads 10 paragraphs in a push notification.) ❌ Adding unsupported formatting. ("<b>Bold Text</b>" won’t work!)
