This endpoint uses the Step object.
Use this endpoint to:
  • Edit the message content or subject of the step
  • Change the delay before this step executes
  • Update the title (for manual steps)
  • Change method/URL (for API steps)
  • Adjust delay logic for conditional steps
You cannot change the type of a step (e.g., from email to linkedinInvite). To do so, delete the step and create a new one. However, you need to add the type field in the request body even if you can’t modify it…
