Scheduled Messages

Overview

The Advanced iMessage Kit SDK supports scheduling messages to be sent at specific times, either once or on a recurring schedule. This is useful for reminders, automated notifications, and regular communications.

One-Time Scheduled Messages

Schedule a message to be sent once at a specific time.

Calculate the scheduled time

Determine when you want the message to be sent.

// Schedule for 3 seconds from now
const scheduledFor = Date.now() + 3 * 1000;

// Or schedule for a specific date/time
const tomorrow9am = new Date();
tomorrow9am.setDate(tomorrow9am.getDate() + 1);
tomorrow9am.setHours(9, 0, 0, 0);
const scheduledFor = tomorrow9am.getTime();

Create the scheduled message

Use the scheduledMessages.createScheduledMessage() method.

const scheduled = await sdk.scheduledMessages.createScheduledMessage({
  type: "send-message",
  payload: {
    chatGuid: "iMessage;-;+1234567890",
    message: "This is a scheduled message!",
    method: "apple-script"
  },
  scheduledFor: scheduledFor,
  schedule: { type: "once" }
});

console.log(`Scheduled: ${scheduled.id}`);
console.log(`Will send at: ${new Date(scheduledFor).toLocaleString()}`);

Monitor the event

Listen for the scheduled message to be sent.

sdk.on("scheduled-message-sent", (data) => {
  console.log(`Scheduled message sent: ${data.id}`);
  console.log(`Message: ${data.payload?.message}`);
});

Complete One-Time Example

import { AdvancedIMessageKit } from "@photon-ai/advanced-imessage-kit";

const sdk = new AdvancedIMessageKit({
  serverUrl: "http://localhost:1234",
  apiKey: "your-api-key"
});

const CHAT_GUID = "iMessage;-;+1234567890";

sdk.on("ready", async () => {
  try {
    // Schedule message for 3 seconds from now
    const scheduledFor = Date.now() + 3 * 1000;

    const scheduled = await sdk.scheduledMessages.createScheduledMessage({
      type: "send-message",
      payload: {
        chatGuid: CHAT_GUID,
        message: "This is a scheduled message!",
        method: "apple-script"
      },
      scheduledFor,
      schedule: { type: "once" }
    });

    console.log(`Scheduled: ${scheduled.id}`);
    console.log(`For: ${new Date(scheduledFor).toLocaleString()}`);
  } catch (error) {
    console.error("Failed to schedule message:", error.message);
  }

  await sdk.close();
  process.exit(0);
});

await sdk.connect();

Recurring Scheduled Messages

Schedule messages to be sent repeatedly at regular intervals.

Daily Messages

// Send "Good morning!" every day at 9 AM
const tomorrow9am = new Date();
tomorrow9am.setDate(tomorrow9am.getDate() + 1);
tomorrow9am.setHours(9, 0, 0, 0);

const daily = await sdk.scheduledMessages.createScheduledMessage({
  type: "send-message",
  payload: {
    chatGuid: "iMessage;-;+1234567890",
    message: "Good morning!",
    method: "apple-script"
  },
  scheduledFor: tomorrow9am.getTime(),
  schedule: {
    type: "recurring",
    intervalType: "daily",
    interval: 1 // Every 1 day
  }
});

console.log(`Scheduled: ${daily.id}`);
console.log(`First send: ${tomorrow9am.toLocaleString()}`);
console.log(`Repeats: every day`);

Hourly Messages

// Send a reminder every 2 hours
const twoHoursFromNow = Date.now() + 2 * 60 * 60 * 1000;

const hourly = await sdk.scheduledMessages.createScheduledMessage({
  type: "send-message",
  payload: {
    chatGuid: "iMessage;-;+1234567890",
    message: "Hourly reminder",
    method: "apple-script"
  },
  scheduledFor: twoHoursFromNow,
  schedule: {
    type: "recurring",
    intervalType: "hourly",
    interval: 2 // Every 2 hours
  }
});

Weekly Messages

// Send a weekly status update every Monday at 10 AM
const nextMonday = new Date();
const daysUntilMonday = (8 - nextMonday.getDay()) % 7 || 7;
nextMonday.setDate(nextMonday.getDate() + daysUntilMonday);
nextMonday.setHours(10, 0, 0, 0);

const weekly = await sdk.scheduledMessages.createScheduledMessage({
  type: "send-message",
  payload: {
    chatGuid: "iMessage;-;+1234567890",
    message: "Weekly team update",
    method: "apple-script"
  },
  scheduledFor: nextMonday.getTime(),
  schedule: {
    type: "recurring",
    intervalType: "weekly",
    interval: 1
  }
});

Monthly Messages

// Send a monthly reminder on the 1st of each month
const firstOfNextMonth = new Date();
firstOfNextMonth.setMonth(firstOfNextMonth.getMonth() + 1);
firstOfNextMonth.setDate(1);
firstOfNextMonth.setHours(9, 0, 0, 0);

const monthly = await sdk.scheduledMessages.createScheduledMessage({
  type: "send-message",
  payload: {
    chatGuid: "iMessage;-;+1234567890",
    message: "Monthly reminder",
    method: "apple-script"
  },
  scheduledFor: firstOfNextMonth.getTime(),
  schedule: {
    type: "recurring",
    intervalType: "monthly",
    interval: 1
  }
});

Yearly Messages

// Send a birthday message every year
const nextBirthday = new Date();
nextBirthday.setMonth(5); // June (0-indexed)
nextBirthday.setDate(15);
nextBirthday.setHours(9, 0, 0, 0);

// If birthday already passed this year, schedule for next year
if (nextBirthday < new Date()) {
  nextBirthday.setFullYear(nextBirthday.getFullYear() + 1);
}

const yearly = await sdk.scheduledMessages.createScheduledMessage({
  type: "send-message",
  payload: {
    chatGuid: "iMessage;-;+1234567890",
    message: "Happy Birthday! 🎉",
    method: "apple-script"
  },
  scheduledFor: nextBirthday.getTime(),
  schedule: {
    type: "recurring",
    intervalType: "yearly",
    interval: 1
  }
});

Schedule Types

once
recurring

Send the message one time only.

schedule: { type: "once" }

Send the message repeatedly.

schedule: {
  type: "recurring",
  intervalType: "hourly" | "daily" | "weekly" | "monthly" | "yearly",
  interval: number // e.g., 1 for every interval, 2 for every other
}

Managing Scheduled Messages

List, update, and delete scheduled messages.

List All Scheduled Messages

const messages = await sdk.scheduledMessages.getScheduledMessages();

console.log(`Found ${messages.length} scheduled message(s)`);

for (const msg of messages) {
  console.log(`  [${msg.id}] ${msg.status} - ${msg.payload?.message}`);
  console.log(`    Scheduled for: ${new Date(msg.scheduledFor).toLocaleString()}`);
  
  if (msg.schedule?.type === "recurring") {
    console.log(`    Repeats: ${msg.schedule.intervalType} (every ${msg.schedule.interval})`);
  }
}

Update a Scheduled Message

const SCHEDULED_ID = "scheduled-message-id";

const updated = await sdk.scheduledMessages.updateScheduledMessage(SCHEDULED_ID, {
  type: "send-message",
  payload: {
    chatGuid: "iMessage;-;+1234567890",
    message: "Updated message!",
    method: "apple-script"
  },
  scheduledFor: Date.now() + 10 * 60 * 1000, // 10 minutes from now
  schedule: { type: "once" }
});

console.log(`Updated: ${updated.id}`);

Delete a Scheduled Message

const SCHEDULED_ID = "scheduled-message-id";

await sdk.scheduledMessages.deleteScheduledMessage(SCHEDULED_ID);
console.log(`Deleted: ${SCHEDULED_ID}`);

Complete Management Example

import { AdvancedIMessageKit } from "@photon-ai/advanced-imessage-kit";

const sdk = new AdvancedIMessageKit({
  serverUrl: "http://localhost:1234",
  apiKey: "your-api-key"
});

const CHAT_GUID = "iMessage;-;+1234567890";
const SCHEDULED_ID = process.env.SCHEDULED_ID;

sdk.on("ready", async () => {
  try {
    // List all scheduled messages
    const messages = await sdk.scheduledMessages.getScheduledMessages();
    console.log(`Found ${messages.length} scheduled message(s)`);

    for (const msg of messages) {
      console.log(`  [${msg.id}] ${msg.status} - ${msg.payload?.message}`);
    }

    // Update a scheduled message
    if (SCHEDULED_ID) {
      const updated = await sdk.scheduledMessages.updateScheduledMessage(SCHEDULED_ID, {
        type: "send-message",
        payload: {
          chatGuid: CHAT_GUID,
          message: "Updated message!",
          method: "apple-script"
        },
        scheduledFor: Date.now() + 10 * 60 * 1000,
        schedule: { type: "once" }
      });
      console.log(`Updated: ${updated.id}`);

      // Or delete it
      // await sdk.scheduledMessages.deleteScheduledMessage(SCHEDULED_ID);
      // console.log(`Deleted: ${SCHEDULED_ID}`);
    }
  } catch (error) {
    console.error("Failed to manage scheduled messages:", error.message);
  }

  await sdk.close();
  process.exit(0);
});

await sdk.connect();

Event Monitoring

Listen for scheduled message lifecycle events.

sdk.on("scheduled-message-created", (data) => {
  console.log(`📅 Created: ${data.id}`);
  console.log(`   Will send at: ${new Date(data.scheduledFor).toLocaleString()}`);
});

sdk.on("scheduled-message-sent", (data) => {
  console.log(`✓ Sent: ${data.id}`);
  console.log(`  Message: ${data.payload?.message}`);
});

sdk.on("scheduled-message-error", (data) => {
  console.error(`✗ Error: ${data.id}`);
  console.error(`  Reason: ${data.error}`);
});

sdk.on("scheduled-message-updated", (data) => {
  console.log(`✏️  Updated: ${data.id}`);
});

sdk.on("scheduled-message-deleted", (data) => {
  console.log(`🗑️  Deleted: ${data.id}`);
});

Use Cases

Daily Reminders

Send daily standup reminders to your team.

// Every weekday at 9 AM
schedule: {
  type: "recurring",
  intervalType: "daily",
  interval: 1
}

Birthday Messages

Automatically send birthday wishes.

// Once per year
schedule: {
  type: "recurring",
  intervalType: "yearly",
  interval: 1
}

Meeting Reminders

Send reminders before meetings.

// 15 minutes before meeting
scheduledFor: meetingTime - 15 * 60 * 1000,
schedule: { type: "once" }

Weekly Updates

Send weekly team updates.

// Every Monday at 10 AM
schedule: {
  type: "recurring",
  intervalType: "weekly",
  interval: 1
}

Scheduling Methods

You can use different message sending methods.

AppleScript
Private API

payload: {
  chatGuid: CHAT_GUID,
  message: "Hello!",
  method: "apple-script" // Default, most compatible
}

payload: {
  chatGuid: CHAT_GUID,
  message: "Hello with effects!",
  method: "private-api",
  effectId: "com.apple.messages.effect.CKConfettiEffect"
}

Private API method is required for message effects and some advanced features.

Error Handling

try {
  const scheduled = await sdk.scheduledMessages.createScheduledMessage({
    type: "send-message",
    payload: {
      chatGuid: CHAT_GUID,
      message: "Test",
      method: "apple-script"
    },
    scheduledFor: Date.now() + 5000,
    schedule: { type: "once" }
  });
  
  console.log("Message scheduled successfully");
} catch (error) {
  if (error.response?.status === 400) {
    console.error("Invalid schedule parameters");
  } else if (error.response?.status === 404) {
    console.error("Chat not found");
  } else {
    console.error("Failed to schedule message:", error.message);
  }
}

Best Practices

Timezone Considerations: All timestamps are in milliseconds since epoch. Ensure your times account for the server’s timezone.

Validation: Always validate that scheduledFor is in the future before creating a scheduled message.

Rate Limiting: Be mindful of creating too many scheduled messages. Each one runs on the server and consumes resources.
