API and integrations – connect business systems easily
What is an API, REST vs GraphQL, integration examples: CRM+newsletter, store+warehouse, ERP+accounting, webhooks. How to connect business systems.
Your CRM, accounting system, store, newsletter and warehouse all work separately. You manually copy data between them? That is wasted time and a source of errors. APIs are the key to connecting everything.
What is an API? 🔗
An API is like a waiter in a restaurant. You tell the waiter what you want, they go to the kitchen, bring your order. REST is the most common API type. GraphQL offers more flexibility by letting you request exactly the data you need.
💡 Pro tip
Before writing custom integration code, check if your systems have ready-made plugins or integrations on their marketplace. A $30 plugin often works better than a week of custom development. Measure cost and time before deciding.

Frequently Asked Questions
- Do I need a programmer for system integrations?
- For simple integrations like store→newsletter, no-code tools like Make or Zapier work. Complex ones like ERP→accounting with account mapping need a developer familiar with both APIs.
