Overview

Zapier is the most popular no-code automation platform with 7000+ app integrations. It uses Zaps (workflows) with triggers, actions, filters, formatters, paths, and code steps.

Capabilities

• Build Zaps with 7000+ app integrations
• Use triggers from apps, webhooks, or schedules
• Add filters to control data flow
• Format data with built-in Formatter
• Use Paths for conditional branching
• Write custom code with Code by Zapier
• Create multi-step Zaps with 100+ steps

When to Use

Trigger phrases:

• "zapier patterns"

• "Automating repetitive business tasks"

• "Connecting SaaS tools without coding"

• "Building simple data pipelines"

• Automating repetitive business tasks

• Connecting SaaS tools without coding

• Building simple data pipelines

• Needing the largest app integration ecosystem

• Non-technical users building automations

When NOT to Use

• Task requires custom code (use Pipedream or n8n)
• You need complex branching logic (use Make)
• Task is about data processing, not automation
• You don't have Zapier account or app connections
• Task requires real-time processing (use streaming tools)
• You need to build a custom API (use development tools)

Pseudo Code

Implementation patterns for common use cases with this skill.

Zap Structure

Trigger → Filter → Formatter → Action 1 → Action 2
                              ↘ Path A → Action A
                               ↘ Path B → Action B

Trigger Types

Type	Example
App Event	New email, New row in spreadsheet
Webhook	Catch Hook (custom URL)
Schedule	Every hour, Daily at 9am
RSS	New feed item

Filter

{
  "filter": {
    "conditions": [
      {
        "field": "status",
        "operator": "str",
        "value": "active"
      },
      {
        "field": "amount",
        "operator": "number_greater",
        "value": "100"
      }
    ]
  }
}

Formatter (Data Transformation)

// Text
{{formatter.text.uppercase(input)}}
{{formatter.text.replace(input, "old", "new")}}
{{formatter.text.substring(input, 0, 10)}}

// Number
{{formatter.number.round(input, 2)}}
{{formatter.number.formatCurrency(input, "USD")}}

// Date
{{formatter.date.format(input, "YYYY-MM-DD")}}
{{formatter.date.addDays(input, 7)}}

// Utilities
{{formatter.utilities.lookup(input, lookupTable)}}

Paths (Conditional Branching)

{
  "paths": [
    {
      "conditions": [
        {"field": "priority", "operator": "str", "value": "high"}
      ],
      "actions": ["send_slack", "create_ticket"]
    },
    {
      "conditions": [
        {"field": "priority", "operator": "str", "value": "low"}
      ],
      "actions": ["log_only"]
    }
  ]
}

Code by Zapier (JavaScript)

// Input from previous steps
const email = inputData.email;
const name = inputData.name;

// Process
const domain = email.split('@')[1];
const isCompany = domain !== 'gmail.com' && domain !== 'yahoo.com';

// Output
output = {
  processed: true,
  domain: domain,
  isCompany: isCompany,
  greeting: `Hello ${name}`,
};

Code by Zapier (Python)

import json

# Input
email = input_data['email']
amount = float(input_data['amount'])

# Process
tax = amount * 0.1
total = amount + tax

# Output
output = {
    'subtotal': amount,
    'tax': round(tax, 2),
    'total': round(total, 2),
}

Webhook (Catch Hook)

# Zapier provides a URL like:
# https://hooks.zapier.com/hooks/catch/123456/abcdef/

# POST data to it
curl -X POST "https://hooks.zapier.com/hooks/catch/123456/abcdef/" \
  -H "Content-Type: application/json" \
  -d '{"event": "new_order", "amount": 99.99}'

Common Patterns

Pattern	When to Use
New Row → Filter → Send Email	Spreadsheet automation
Webhook → Process → Multiple Actions	Custom event handling
Schedule → Fetch → Transform → Store	Regular data sync
Path A / Path B	Conditional logic
Formatter → Clean Data	Data normalization
Code Step → Complex Logic	Custom transformations

Error Handling

Error	Cause	Fix
Filter stopped Zap	Conditions not met	Check filter logic
Rate limit	Too many tasks	Add delay step or use Paths
Code error	Syntax or runtime error	Test code step individually
App disconnected	OAuth token expired	Reconnect app

Red Flags

• Not testing Zaps before enabling
• Ignoring error handling in Zaps
• Missing logging and monitoring
• Not documenting Zap logic
• Ignoring rate limits and quotas

Verification

• Zaps are tested end-to-end
• Error handling is in place
• Logging and monitoring are configured
• Zap logic is documented
• Rate limits are respected

Process

1. Analyze the task requirements
2. Apply domain expertise
3. Verify output quality

Anti-Rationalization

Rationalization	Reality
"Manual is faster for one-off tasks"	One-off tasks become recurring. Automate early, save time later.
"I will add error handling later"	You never do. Handle errors from day one.
"Automation is overkill"	If you do it twice, automate it. If you do it daily, it is critical infrastructure.
