unknown_parameter

HTTP 400 · retryable is false

Kabu refuses a field it does not know rather than ignoring it, so a misspelt expries_in fails loudly instead of quietly using the default. param names the field; errors lists each one when there are several.

What to do: remove the field or correct its name. Responses work the other way: they may gain fields at any time, so ignore the ones you do not know.

The response

Every error comes as application/problem+json; Errors explains each field.
