[SOLVED] How to add a Tuleap Team to mattermost

Hi all,
I installed mattermost server in my machine and i want to link it to tuleap,
My objective is the user can sign in to tuleap team by add the tuleap url and can find all tuleap team members and can doing discussions with them.
Any one have an idea about a solution for that.

About mattermost and tuleap:
I installed the mattermost server : https://www.unixmen.com/installing-mattermost-rhel-7-1/
I added the mattermost plugin to tuleap ( + mattermost git and mattermost agileDashboard)
About the webhook when creating the bot it’s generated from the mattermost server as mentioned in this link :

Thanks for posting back your solution @marouane!
