HTTP 400 · Invalid parameter

A query or body field is missing, malformed, or outside the allowed range.

## Why it happens

The request reached the API, but a value the endpoint needs could not be parsed or accepted.

## How to fix it

Read the detail field for the field name, then compare the request with the endpoint reference. Limits and allowed values are published per endpoint.
