How can I connect an external chatbot code with my callin.io Table?

Hello, I have some code on an external chatbot platform that enables users to log in using credentials stored in a callin.io Table. The process is as follows: a user provides the required information (email and password, for instance), and the chatbot runs a script. This script previously verified if the user's input existed in the callin.io Table and if the password matched the email. However, I'm encountering difficulties connecting the code to my callin.io Table. I require a URL to establish this connection. I've included a screenshot of the code below; any assistance would be greatly appreciated.
