Symphony Elements

Symphony Elements enable bots to send messages that contain interactive forms with pre-designed text fields, dropdown menus, person selectors, buttons and more.

By reusing our standard UX component libraries, Elements provide developers with out-of-the-box tools to easily create interactive bot messages that look and feel like they belong in Symphony.

The Elements

Symphony Elements are a library of pre-designed reusable UX components (text fields, dropdown menus, person selectors, buttons and more). You can use the Elements to create forms that enable Symphony users to interact graphically with bot messages:


  • It is only available on pods that have been updated to 20.3.1 and running an Agent 20.3.1 (2.57.0) or above.

  • Our iOS application (versions 1.56.0 and above) fully supports Symphony Elements.

  • Our Android application fully supports Symphony Elements with Agent version 2.57.0 and above.

  • If you are using a custom SDK to build your Bot, please note it needs to support the modified JSON payload response, see Symphony API Specification located here We advise you to upgrade to a supported Symphony SDK.

Known Limitations

  • Once the user has submitted the form, it becomes disabled. However, if the conversation is reloaded, the form resets and the user is able to send a new reply. If your workflow requires a single reply per user, please implement this control on the Bot side.

  • User replies are not processed by DLP (Data Loss Prevention)

  • In read-only rooms, only the owners of the room are able to interact with Symphony Elements. For non-owner users, messages with Elements will be disabled
