REST API producer #468

Background [Optional]

I was trying to call "/Producer" Api from azure Databricks. and this /Producer api is written in C#. I want to send the data to my c# Application and not to any DB. i have install spline agent compatible with the Azure Databricks Runtime versions. but whenever i ran some query and and i am enabling the lineage tracking in python the it gives me error that za.co.absa.spline.harvester.exception.SplineInitializationException: Spark Agent was not able to establish connection to Spline Gateway. HTTP Response: 404

Question

How i can hit the Custom producer API and send the spline data to it using spline agent from databricks. So that i can use it in my business logic ?
