Hey ​@anish2002 I just checked with support and they caught the issue!

You’re using a dynamic block, not an external request. Dynamic requests do not allow mapping (since they have to follow Manychat’s API formatting).

To use mapping you need to use external requests.

Thank you for your response ​@Gustavo Boregio . Can you help with where and how to setup up  external requests in a way so I can use response mapping!

Hey ​there, here’s the documentation: https://help.manychat.com/hc/en-us/articles/14281285374364-Dev-Tools-External-request

Hope this helps!!
