# Relation Types
## Finds all the relation types matching the given criteria.
> Returns relation types matching the given search criteria.\
> Only parameters that are specified in this request and have not \null\ values are used for filtering.\
> All other parameters are ignored.\
> The returned relation types satisfy all constraints that are specified in this search criteria.\
> By default a result containing 1000 relation types is returned.
