Stages are different possible states a box can be in. The list of valid stages a box can be in are defined in the pipeline it belongs to. All boxes in the same pipeline all have the same set of permissible stages. Listing the stages for a given pipeline can be done by (getting a specific pipeline)[reference#getting-a-specific-pipeline] or using the list stages endpoint below. To set what stage a given box is in, update the stageKey property of a box using the edit box endpoint.
This call lists the stages defined in a pipeline. Remember, this is only the definition of the stages - to change what stage a box is in, simply update the box with a new stageKey.
