Zendesk Apps, Chosen Carefully

The marketplace has hundreds of apps. Your agent sidebar has room for about four before people stop reading any of them.

What apps actually do

Most Zendesk apps add a panel to the agent interface, usually beside the ticket, showing information from another system or letting the agent act on it without switching tabs.

Some are built by the other vendor, some by partners, some by individuals. That difference matters more than the feature list, because it predicts whether the app still works next year.

The categories worth having

Customer context. CRM or billing data in the sidebar, so the agent knows who they are talking to.
Order lookup. Essential for ecommerce, removes a whole round trip per ticket.
Escalation. Creating a Jira issue or a Slack thread without copy-paste.
Time tracking. If you bill for support, or need to know where agent hours go.
Quality and workflow. Anything that removes a repeated manual step.

Vetting an app before you install it

Who publishes it, and when was it last updated? An app untouched for two years will break on the next platform change.
What data does it read? Support queues hold sensitive information, and an app that reads every ticket deserves a proper review.
Does it remove work or just show information? One app that removes a step beats three that display things.
What happens when it fails? An app that blocks the agent interface when its API is down is a support outage with extra steps.

Frequently asked questions

Are Zendesk marketplace apps free?+

Many are, some are paid, and some are free but require a paid account on the other vendor side.

How many apps should we run?+

As few as remove real work. Past four or five sidebar panels agents stop reading any of them.

The integration with no sidebar

Ticket Merger works on the queue rather than the open ticket, so it adds no panel and removes tickets instead of showing information.
