Day 4: Scheduling, Triggers, and Error Handling

The Four Trigger Types

Every automation starts with a trigger. Picking the right trigger type avoids wasted operations and ensures automations fire at the right time.

1. Schedule
   Run at fixed times: every day at 7am, every Monday at 9am
   Use for: reports, briefings, digests, recurring tasks

2. Webhook
   Run when another app sends data to a URL you provide
   Use for: form submissions, payment events, app integrations

3. Watch / Poll
   Check for new items at an interval (every 15 min, 1 hour)
   Use for: new emails, new spreadsheet rows, new files

4. Instant
   Fire immediately via real-time event push
   Use for: Slack messages, form submissions with instant hooks

Error Handling That Actually Works

Automations fail. APIs go down. Response formats change. Rate limits get hit. The question isn't whether your automations will break — it's whether you'll know when they do.

In Make.com, right-click any module and select Add error handler. Three options:

• Resume: Continue with a fallback value. Good for non-critical steps where partial results are acceptable.
• Rollback: Undo all changes from this run. Good for database operations where partial completion is worse than no completion.
• Break: Stop the run and save it as an "incomplete execution" you can retry later. Best for AI-powered workflows.

In scenario settings, enable Store incomplete executions. This saves every failed run so you can retry it with the original data once the issue is fixed.

Build: Daily 7am AI Briefing

This scenario runs every morning and delivers a personalized briefing to your inbox. Here's how to build it:

Trigger: Make.com Schedule. Set to run daily at 7:00am in your timezone.

Module 2: Google Calendar — List Events. Fetch events for today only. Set the time range from midnight to midnight, or "today" using Make's date functions: {{formatDate(now; "YYYY-MM-DD")}}T00:00:00 to {{formatDate(now; "YYYY-MM-DD")}}T23:59:59.

Module 3: Fetch Tasks (optional). If you use Todoist or a Google Sheet task list, pull open items due today.

Module 4: OpenAI — Generate Briefing.

Create a concise morning briefing. Direct, no fluff.

Today's Meetings:
{{calendar_events}}

Open Tasks:
{{tasks}}

Format exactly as:
MORNING BRIEFING — [day, date]

MEETINGS:
[bullet each meeting with time and title]

TOP 3 PRIORITIES:
[the 3 most important tasks by urgency]

WATCH OUT:
[meetings requiring prep, upcoming deadlines, follow-ups needed]

Module 5: Gmail — Send Email. Send to yourself. Subject: Morning Briefing — {{formatDate(now; "MMM D")}}. Body: the AI output. Plain text works fine — no HTML formatting needed.
