Version from the first release
Adding versioning after external consumers exist is a migration project. Adding it on day one costs a path segment.
Prefer additive change over new versions, but have the mechanism ready.
Paginate everything that can grow
Any collection endpoint without pagination is an outage waiting for a customer with more data than you tested with.
Cursor pagination handles insertion during traversal better than offset pagination.
One error shape, everywhere
A consistent error body with a machine-readable code, a human message, and a request identifier makes integration and support dramatically cheaper.
Include the request identifier in logs so a customer report maps to a trace in seconds.
Where to go from here
If you are weighing API design for an upcoming project, the useful next step is usually a short scoping conversation rather than a longer article. Bring your constraints — budget, timeline, existing systems, and the team you already have — and the decision usually resolves itself in an hour.
We run these as a fixed-scope discovery session with a written recommendation at the end, including the cases where our advice is that you do not need us.
