If there is an existing Length Of Stay price for the specified Listing and Length Of Stay then it will be overwritten with the value specified here.
Lengths of Stay are created with thresholds for individual lengths, and apply until the next length threshold is reached.
E.g. if nightly price is added for 5 days and 30 days, then during pricing any length between 5 and 30 will be priced at the 5-day level.
Any length at 30 or above will be priced at the 30 day level.
The currency that will be used for this endpoint is the same currency retrieved from the listings endpoint.
