The Entry to "Connecting Tools" via API Integration
Automation's core is "trigger app B from an event in app A." There are broadly 3 means: Zapier / n8n / custom scripts.
The 3 Options
| Zapier | n8n | Custom script | |
|---|---|---|---|
| Difficulty | Low (GUI) | Mid (GUI + flexible) | High (code needed) |
| Flexibility | Mid | High | Highest |
| Data management | Cloud | Self-hostable | Fully your own |
| Suits | Non-engineers | Intermediate | Developers |
How to Choose
- First make a "working experience" with Zapier (minimal learning cost)
- If you need confidential data/complex branching, n8n (self-hostable)
- Fine control/large-volume processing: custom scripts
How to Embed AI
Each tool can insert AI steps (summarize/classify/generate). "Receive email → summarize with AI → Slack notify" is a standard integration.
Caution
- Manage API keys/credentials with each tool's secret feature (don't write in plaintext)
- Mind paths where confidential data passes through the cloud; self-host depending on requirements
- Always test with small volume so a malfunction doesn't mass-send
