# bulkUpsertWorkflowSteps

> Atomically replace all steps in a workflow. Steps with a matching `stepId` are updated; steps without an ID (or with a new ID) are created; steps that existed before but are absent from the input are deleted.
Optionally updates `startStepId` and the trigger configuration in the same call. Maximum 60 steps per workflow.
