Self-Service Flow Steps let an integrator deploy a web API as a Flow Step in Marketo Smart Campaigns.

A Flow Step Service can:

  • Receive lead and related data.
  • Process the data, including calling other web services.
  • Write lead and activity data to Marketo through a callback.

For implementation details, see the developer documentation on GitHub.
