Form Flash Messages

Last updated on October 09, 2026.

Flash messages are used to create notices and alerts, e.g. on form submission.

Important

You can use the Instance Admin to create flash messages and alerts for your forms. Please refer to the Form Builder documentation for more details.

Setting form notice or alert values in the form

You can add values for messages as part of a form configuration, for example:

Interpolation

Values for keys are processed using a Liquid parser so that they can be interpolated in the context of the current form:

Note

Put single quotes () around the value when it contains Liquid, so the YAML stays valid.

Displaying flash messages

Messages can be displayed on a page using the context variable.
