Hello everyone,
I am currently working on a Slack bot that is supposed to send a message via a webhook if a ticket has no owner for more than 3 days.
The basic function works - but the trigger logic is unfortunately not yet reliable: Sometimes the message is sent as requested, sometimes simply nothing happens.
Do any of you have experience with this or any ideas on how to map this trigger cleanly and reliably?
Thank you in advance! 
I am currently trying to proposing Zammad to my company, but one of the requirements is to be able to use Slack to create tickets automatically. I am using n8n to provide the integration with Slack trigger node. I can create a new ticket, and pass Slack’s message body, user’s ID, channel ID, and message ID into the ticket body. However, I am not able to attach the attachment from Slack to the new ticket. This is the deal breaker for the company. Might try another ticketing system that is able to provide easy integration and capture the attachment within the Slack message.
Did you check: Articles — Zammad System Documentation documentation
@dominikklein Thank you for directing me to the API document, with lots of try and error I managed to complete the workflow that create new ticket when received message and attachment(s) at my Support Slack channel.
