Connecting Your Business Applications: A Plain-Language Guide to Integrations

If your team regularly exports data from one system and imports it into another, you are doing an integration by hand. Automating that work can save time and reduce errors — when it is designed well.

The building blocks

• APIs let one system read or write data in another, with permission
• Webhooks notify another system when something happens, like a new order
• Scheduled syncs move data at set intervals when real-time updates are not needed
• Middleware sits between systems to translate and route data

Start with a data map

Draw your main systems and the information that moves between them. For each type of data, decide which system is the source of truth. This single exercise prevents many integration problems.

Design for failure

Networks fail, APIs change, and data arrives in unexpected formats. Good integrations validate data, retry safely, avoid creating duplicates, and alert someone when they need attention.

Keep it documented

Document each integration: what it does, which credentials it uses, who owns it, and how to troubleshoot it. Undocumented integrations become risks when people change roles.
