An ERP rarely works alone. Companies often have an e-banking service, a store, a tax-invoicing system, or a communication tool. This is where APIs (Application Programming Interfaces) come in, letting systems exchange data without manual re-entry.

The framework we use auto-generates a REST API for every DocType, so building an integration usually means sending or receiving data over a documented endpoint rather than writing a new layer from scratch. Webhooks are also useful: when an event like a new invoice occurs, the system automatically notifies another system.

Practical examples: linking sales to electronic tax invoicing, syncing balances with a bank account, or pushing store products from inventory. Good integration reduces errors and saves team time, provided permissions and metadata are well organized.

The key point is not to re-enter the same number in two places. Sound integration makes one source the single source of truth and derives the rest from it. This needs a little planning of what is the source of truth for each piece of data.
