Recieving images with rasa bot


I am new to Rasa, and I’m working on a chatbot. I want to implement an image detection feature with google vision in my custom action but i would need to receive the image path from the user. I plan to pass this through the metadata tag, in my post request. I’m aware I need to implement this with with a custom connector but I have zero idea how to go about that. Would a custom connector also enable Rasa detect that this is a special input and thus trigger the custom action.

Any guidance or resource on how to go about implementing the custom connector and it’s detailed features would be extremely helpful.

Thanks in advance!
