# `unsupported_version`

**Status 404.** That API version is not served here.

## What it means

The version in the address is not one this platform serves. `supported_versions` lists the ones that are.

## What to do

Use one of them: the version is the part of the address right after `/api`.

## Safe to send again?

Not as it is. Change what the answer points to, then send the request.

## What else the answer carries

- `supported_versions`: The versions this platform serves.
