The ModuleX Customer.io integration lets a ModuleX agent operate Customer.io on your behalf, running create and send actions across events and customers to segments, directly from a plain-English request, using your organization's own Customer.io credentials. No pre-built workflow is required: the agent picks the right Customer.io action for the task.

Customer.io is a marketing & advertising platform. ModuleX adds the agent layer: ask for an outcome and it selects and runs the right Customer.io action. Or, when you want a repeatable process, the composer assembles a Customer.io workflow for you, streaming the nodes onto the canvas as it builds.
