Feature Request: Pass parameter to canned responses

[paymanzafar1]

Hi,
I think it is a good feature to pass a parameter like custom fields or guest name to insert in a saved canned response.

Is your feature request related to a problem? Please describe.
I want to create a canned response to say hello to the visitor and indicate his/her name. I used the registerGuest api function to send the guest name to RocketChat. I want to be able to pass the guest name as a parameter to the canned response.

Describe the solution you'd like
Use a parameter like {GuestName} or {CustomField} in the canned response, and system fills this variable value in the response.
