Application: feedback

Serves contact pages on GOV.UK


This app collects feedback from users via contact forms rendered on GOV.UK. This data is then sent to support-api app to be dealt with.

Live examples


  • Feedback: All the data received from contact forms is considered to be “feedback” of some form or other and relates to pages published on GOV.UK.
  • Anonymous Contact: Part of the feedback collected by this app is anonymous, when it’s submitted via an anonymous contact form.
  • Named Contact: In contrast with the Anonymous Contact feedback, this is submitted via a form that will require you to identify yourself. This data is sent directly to Zendesk.

Completed Transaction feedback forms

Service Feedback

Most of the /done/completed-transaction pages render a Service Feedback form. An example is:

Assisted Digital Feedback

There are also three assisted digital feedback forms:

Transaction finished

The transaction finished page can be found here: This doesn’t display a form, just content to inform the user that the transaction is finished.

Where is the data sent?

The Service Feedback form fields also exist within the Assisted Digital Feedback form. They are foundationally the same, but Assisted Digital Feedback has some extra fields.

The Service Feedback form data from both types of form is sent to the Support API. It can be viewed using the Support app within the Feedback Explorer.

In addition to sending some data to the Support API, the data from the other fields (from the Assisted Digital Feedback form) plus some data from hidden fields appended using JS (referrer and javascript_enabled) are written to a Google spreadsheet.

For submitting the Assisted Digital Feedback form, you will need to get the Google API credentials from AWS secrets/integration. To use them locally, create a .dotenv file and write them in:


The .env file is listed within the .gitignore file. Do not push the .env file to version control.

Completed transaction feedback forms were previously rendered by the Frontend application. Rendering was moved into this application which enabled the implementation of form validation.
