APIs are the backbone of automation. Here's how to pick the right approach for your needs and budget.
Direct Integrations
- Best for simple, one-to-one connections
- Fastest to build, lowest cost
Middleware Solutions
- Great for connecting multiple systems
- Tools: n8n, Make, Zapier
Custom Integrations
- For unique, complex, or high-volume needs
- Requires more dev time, but maximum flexibility
Case Example: Custom vs Middleware
One client started with Zapier, then moved to custom Python integrations as their needs grew—saving £600/month.
Insider Insight
Start simple. Only go custom when you've outgrown off-the-shelf tools.
Pitfalls
- Overengineering simple integrations
- Not documenting API changes
