You need to perform a quick ingestion test to evaluate your configuration.

 The simplest recommended way to perform a quick ingestion test to evaluate your configuration is by using the Event Playground. The Event Playground allows you to easily test application events, actions, and CX flows by ingesting a test event with test values you provide via a dedicated form. The submitted test data runs through the entire CDP flow, which is then displayed in the playground as a visualization of that flow and its results. It helps identify errors in the different steps: ingestion, schema mapping, identity resolution, CX flow steps, CX flow actions, providing transparency and confidence in the flow of data1.
