@murugan

Can you please give us a bit more information regarding your use case / setup?

- Which library versions are you using? Are you still using `rasa-core` / `rasa-nlu` or already using `rasa`?
- What are you trying to achieve (why do you need your own webservice in addition the existing rasa api?

> actually i am doing custom chatbot developement

That’s totally fine, but when you are trying to parse messages with NLU, pass it to Core, then it seems like exactly what `rasa` is doing 😉 Which parts of the chatbot do you want to customize? And can you please my answers from above?

Maybe this part of the docs can help you [Jupyter Notebooks](https://rasa.com/docs/rasa/api/jupyter-notebooks/).

Thanks @Tobias_Wochinger i want to customize only RASA core part, …internally nlu sends higher intent and confident in to rasa agent right , , now my question is i need to edit the 1st three intent to rasa core

Wouldn’t it be easier to write a [Custom NLU Components](https://rasa.com/docs/rasa/api/custom-nlu-components/#custom-nlu-components) in that case or to use the [Mapping Policy](https://rasa.com/docs/rasa/core/policies/#mapping-policy) to modify the tracker?
