Access Tokens and Webhooks

Access Tokens and Webhooks

I have a linux server application that I want to be able to talk to the cliq chatbot and get a response back to that linux server application.
 
This is for the linux server application to check the chat/channel's message history in Cliq.

The Zoho API console wasn't working for me as getting the access token through the POST request only gave me in 500 error code.

A small workaround attempt I did was to go into Bots & Tools tab on Cliq then navigated to the webhooks token. This only allowed me to POST, send messages to the chat/channel. This doesn't work for the GET method. I need to be able to have the server application retrieve/view the messages in the chat history.

Any ideas or suggestions on how to resolve this? Either regarding the zoho api token generation or the webhooks?

I am also working on using a chatbot. Would the chatbot be able to talk to the linux server application?
