Define how much cost for every event at Plan definision after complete set-up your billable metric

  • Go to the Plan Definition page
  • Navigate to Advanced Setup, add a billing model under Usage-based billing, and choose your Pricing type:
    • Standard pricing A fixed rate is applied for each unit of usage. For example, if the unit price is 0.05andausergenerates100events,theywillbecharged0.05 and a user generates 100 events, they will be charged 5.
    • Graduated pricing Usage is divided into tiers, and each tier has a different rate. For example:
      • First 100 events: $0.05 each
      • Next 200 events: $0.03 each
      • Remaining events: $0.01 each
        This model encourages higher usage by reducing unit costs at higher volumes.
