Is this an API bug where a Fees PUT request returns no response?

Is this an API bug where a Fees PUT request returns no response?

Hello aearl23,

This is expected behavior. The PUT fees endpoint is used to update the Amount of an existing fee. If the value you send is identical to the current one (in this case, "27.00"), no actual update occurs, so the API returns a 200 OK with an empty response body.

This doesn't indicate an error; it's just letting you know the request was valid, but no changes were made.

Thanks!
