The /v1 surface is stable. We will not ship a breaking change inside /v1. Once a route, request shape, or response shape is published, it stays — that’s the whole point of a v1.

​
What counts as breaking

These changes require a new version namespace. They will never ship inside /v1:
  • Removing or renaming a field in a response.
  • Removing or renaming an endpoint.
  • Changing the type of a field (e.g. string → number).
  • Adding a required request field.
  • Tightening validation (e.g. a previously-accepted value now rejected).
  • Changing the meaning of a value (e.g. "Draft" → "draft").

​
What’s safe to ship without a version bump

  • Adding a new endpoint.
  • Adding a new optional field to a request.
  • Adding a new field to a response.
  • Adding new enum values (where consumers were already prepared to handle unknown values — we document this per-route).
  • Loosening validation.
  • Performance improvements.
  • New error.code values inside an existing error.type.
Build your client tolerantly — ignore unknown response fields, treat unknown enum values as a degraded-but-safe default.

​
When breaking changes happen

A new versioned namespace ships (e.g. /v2/foo). The old /v1/foo stays alive at least 12 months with the deprecation headers below. Existing consumers get the full 12 months to migrate. 
Deprecation: true
Sunset: Sun, 04 Apr 2027 00:00:00 GMT
Link: <https://docs.autousers.ai/api-reference/foo>; rel="successor-version"
Watch for these headers in production responses; surface them in your own logs so a quietly-introduced sunset doesn’t become a Friday emergency.

​
Aliases

When we rename an internal noun to a product noun, the old route stays working as an alias for the full sunset window. Today the canonical example is templates vs dimensions:
CanonicalAlias (deprecated)Status
/v1/templates/*/v1/dimensions/*Deprecation: true, Sunset: Sun, 04 Apr 2027 00:00:00 GMT
Both keep working through 04 Apr 2027. After that the alias 410s. The reference only documents /templates.

​
Header-pinned versions (future)

If we ever need version-specific behaviour on the same URL — rare — clients will pin via: 
Autousers-Version: 2026-05-04
The default is the current version. Old dated versions stay reachable for at least 12 months from the day they are superseded. Not yet implemented. When it ships, we will add a per-route version selector and the request/response examples in the reference will gain a version dropdown.

​
What we will not do

  • Rename fields silently. Renames ship as additions for one version and removals in the next; the rename always crosses a version bump.
  • Repurpose error.type values. New conditions get new types.
  • Change the response shape of a route inside a version, even by adding required fields. Additive optional fields only.

​
OpenAPI as source of truth

The full machine-readable contract lives at /api/v1/openapi.json. SDKs, the in-page playground, the CLI, and the MCP server all derive from it. If the spec and this prose disagree, the spec wins; file an issue.
