How to execute slack bot from message send through web-hook?

Question

I created a simple Alexa app that posts a text into a slack channel.

I defined the message so that it would trigger a slack bot, that is running in the same channel. Like what happens when I type the text manually.

Example: botname action parameter e.g. herbert ping 192.168.1.1

The message post via web-hook comes in exactly in the same way BUT it does not trigger my bot.

What am I doing wrong? Can somebody please provide a hint.

You can not execute slash commands through incoming webhooks, but you can do it with the undocumented API commands chat.command. See also this answer.
