Hi All, I was facing issues while creating custom connector for my customized ui as well as whole functionality. But after countable amount of efforts and time I managed to implement custom connector using RestInput class template from rasa docs Custom Connectors Below are the steps that I followed : Create python script file and copy paste RestInput template code and fix all imports. Below is my custom connector file : MyIo.py (4.4 KB) Do all custom connector related configuration in credentials.yml file MyIo.RestInput: a. MyIo is the script name i.e MyIo.py b. RestInput is the class name inside MyIo.py script file. Run your custom action server with the usual command: i.e python -m rasa_sdk --actions actions Run your rasa server using following command : To start rasa server with cross origin access use below command: rasa run -m models --enable-api --cors "*" with debug mode rasa run -m models --enable-api --cors "*" --debug Also set environment variable path for your custom connector file like below PYTHONPATH=“path to your custom connector file” Note : Your webhook url will be as per the below format http://localhost:5005/webhooks/myio/webhook In above url myio is the name of component that we are returning from name method inside of our custom connector class i.e RestInput. After completing you can connect it with any front-end or just test it with postman rest api testing tool.

Hi With out implemnting custom connector, i can test rasa using postman using url=http://localhost:5005/webhooks/rest/webhook. is there any default implementation

Yeah yeah @selvamsandeep you can test it without using custom connector. you just need to specify rest: in your credentials.yml file that’s it. :slightly_smiling_face:

Hi @prashant_kamble , I am trying to do the same steps, but always got the error ‘Module MyIo not found’. Can you share please the project structure or guide me, please, where to put that custom connector file?

Hi @dmlapteacru , You will need to add one environment variable and set path of your project into that variable. for e.g PYTHONPATH=“path to your custom connector file”. Afte that you can check out and let me know if it solved your issue pal :slightly_smiling_face:

This is so great, thank you so much! One question: where do you put the webhook url? In the credentials file? Endpoints? Thank you!

Hi @ellav , I am happy that it helped you :slightly_smiling_face:. If you are using custom front end with custom connector, you will need to put webhook url in front end javascript file where you will be making ajax requests to the bot.

Aaah ok! Thank you :slight_smile: I am making an application for a small robot to work via voice (so with ASR and TTS), so I probably need to add the webhook url to the MQ part.

I am not clear about MQ part, but you can try.
