What is response mapping?Last Updated: June 27, 2019
Short Answer: Response mapping is what you'll need to do to "save" the response from CodelessBot to a ManyChat custom field.
When the ManyChat External Request contacts CodelessBot and receives an "answer". Those answers are not automatically saved as ManyChat custom fields. You must use the External Request's response mapping feature to tell ManyChat which response to save and as what field.
CodelessBot may respond with many answers that you don't need. You only need to map and save the ones that are of interest to you.
In the example, you're saving/mapping the value for the CodelessBot response "cbot_rsp" to the your ManyChat custom field "My_TextField2".
