How do I trigger when a Zendesk ticket gets a comment?

Short answer: Drop the "ZendeskTicket Commented" trigger on your workflow canvas, add filters if you want them, and publish. It fires within seconds of the event in Zendesk, not on a polling schedule.

FAQ

Questions about Ticket Commented.

How does the Ticket Commented trigger work in Zendesk?
Fires when a comment (public or internal) is added to a Zendesk ticket. Common use: notify Slack of customer replies, log activity, or mirror conversations into a CRM.
Is the Ticket Commented trigger real-time?
Yes. Ticket Commented uses webhooks or push subscriptions, not polling. Your workflow fires within seconds of the event happening in Zendesk.
What data does Ticket Commented return?
The full event payload from Zendesk. The output shape table on this page lists every field, its type, and an example value so you can map fields into downstream nodes.
Can I filter Ticket Commented so only some events start a workflow?
Yes. Add a Filter node right after the trigger and match on any field, whether that's subject, sender, status, or anything else in the payload. Workflows only continue when the filter passes.
Do I need Zendesk admin permissions to use Ticket Commented?
For most Zendesk accounts a standard user can authorize the trigger. Some Zendesk plans require an admin to enable third-party webhooks. Check Zendesk's docs if the trigger fails to register.
