Open and flexible ticketing system

Is Zendesk an open source ticketing system?

As your business grows, so will the demand on your IT team. Meet demand without buckling under the pressure by investing in a ticketing system. Ticket system software assigns a number to every request and logs it as a ticket in your database, which helps your team track, monitor and resolve the increasing number of support requests from both customers and internal users. Zendesk is an open API ticket system which means third party developers can build new integrations on our platform. Unlike open source ticketing systems, Zendesk software offers all the advantages of open source ticketing without your team having to build a system from scratch. Zendesk’s open API ticketing system software gives your team all the tools they need to build as much—or as little—as they want.

Developer tools at your fingertips

Zendesk provides a set of API and SDK (software developer kit) developer tools to help you customize and maximize how Zendesk functionalities can support your business. These include:

The Zendesk Web Widget

  • Easily embed omnichannel support on any webpage with a single snippet of code
  • For advanced customization, use Zendesk’s Javascript API to authenticate users, personalize their behavior, and choose channels available in the widget


  • Build your own widget from scratch
  • Completely customize the widget’s look and feel to match your brand

Zendesk Mobile SDK

  • Integrate omnichannel support natively into any mobile app—iOS, Android, and Unity
  • Your developers can install and configure the SDK right out-of-the-box
  • Customize features like colors, fonts, and UI behavior
  • Or you can build a custom navigation for an even more personalized user journey

Build customer apps and integrations

With the Zendesk Apps Framework, you can build customer apps and integrations specifically for Zendesk ticketing system and live chat software. Our Apps Framework is built on open standards, which means your developers don’t have to feel restricted as they create. Instead, developers can use their favorite libraries and frameworks for their ideal look, feel, and interactivity. Zendesk Apps Framework also comes with a development toolkit to simplify testing and deployment to production. So your business can get these apps and integrations to customers as quickly and efficiently as possible.
