Why it matters for an FDE
Business systems often need to exchange customer, order, or event data. JSON is one common format you’ll inspect while building those connections.
The idea
JSON is like a labeled form. Each key names a field, and its value holds the information. For example, { "status": "ready" } says that the status field has the text value “ready”.
Worked example
An order service might send { "orderId": 42, "status": "packed" }. An integration reads those fields and passes the information to another system. Names, data types, and required fields need to match what the receiving system expects.
Common mistakes
- Missing quotation marks or commas.
- Sending a number as text when the receiving system expects a number.
- Assuming two systems use the same field names.
