Frequently Asked Questions

What are API integration platforms? 

API integration platforms (or iPaaS) are a cloud service that connects different applications and data sources via their APIs. It provides tools (like drag-and-drop editors or code-run environments) to create automated workflows that move or sync data between apps without manual intervention.

Why do businesses use API integration platforms?

They save time, reduce errors, and enable automation. Instead of manually exporting, transforming, and importing data between systems, an integration platform handles it automatically. This frees staff, speeds up processes, and scales easily as your business grows.

How much do these platforms cost?

Pricing varies widely. Some (like Zapier and n8n) offer free tiers. Others use subscription models (Zapier ~$20/mo, Power Automate $15/user/mo) or task-based pricing (Tray.io from $500/mo or more). Enterprise platforms (Workato, MuleSoft) often start in the tens of thousands yearly. Review each vendor’s pricing page or speak to sales to estimate your costs.

Which is the best API integration platform?

The “best” platform is the one that fits your use case. For non-tech users, Zapier or Integrately are often recommended. For developers, n8n or Pipedream offers flexibility. Workato, MuleSoft, or TIBCO may provide the power enterprises need. Evaluate free trials to see which interface and connectors work best for your team.

How do I get started with integration tools?

Identify a simple workflow to automate (e.g., syncing contacts between apps). Sign up for a free platform trial (Zapier, Make, etc.) and try building that workflow. Most vendors have tutorials and template libraries. Start small and gradually expand to more complex flows as you get comfortable.
