# addPipelineStages

Append one or more stages to a pipeline (by pipelineId). Each stage: name (required), plus optional description, order, isTerminal, terminalType (WON|LOST|NEUTRAL), winProbability (0-100). Owner-only: the pipeline must be OWNED by your organization. Returns the pipeline with its full, ordered stage list.
