Responding in Skype channel with info. coming form an external source

Hi,

I'm using Skype channel for the Bot to communicate with the user.
I'm trying the below flow

Bot: xxxx (request input from user in Skype)
User: xxxx (responds with info. in Skype)

Bot --> makes a call to a Webhook which triggers Workato (automation platform) to process the data
Workato makes a POST call (https://support.snatchbot.me/reference#post-message) to the Bot with the response.

We are able to view the response from Workato in Snapchat's reports (https://snatchbot.me/reports) but it doesn't appear in the Skype conversation.

Could you please suggest how we can respond the user in Skype with the response coming from the external source. (POST call from Workato)
