Hi,

I think about create an interface to our ticketing system (OTRS).  
After some search i haven’t find any existing interface.

The purpose is to have a command to show a ticket summary by his id and on the over hand to send message to user when a ticket in is queue is modified.

To do that what is the best betwenn App and bot ?

Thanks

I believe, that apps can only react to direct user interaction, like calling `/poll`. So for the second part of your interface you would most likely need a bot/incoming webhook.

Since yesterday i’ve search some information (documentation is very poor ☹ ) and found this video :  
Rocket.Chat Apps Development Webinar

[![](https://us1.discourse-cdn.com/flex021/uploads/rocketchat/original/2X/d/d4e6502a44307fe99db965b46c68a0d8c761d3f1.jpeg "Rocket.Chat Apps Development Webinar") ](https://www.youtube.com/watch?v=PaFPeD6QG9k)

and at 20:34 after deployement the app expose a POST webhook on localhost:3000/api/apps/public/…

So it seem an app be able to react a some external events like the BitBucket App : [https://docs.rocket.chat/guides/rocket-chat-apps/atlassian/bitbucket-server-integration](https://docs.rocket.chat/guides/rocket-chat-apps/atlassian/bitbucket-server-integration)

Yes i’ve used this app as an example.

I made an app but it’s not clear in which case it’s better to create an app and in which cas a bot.
