# Ionic Capacitor SDK: Prefill the widget form

Prefill feedback form fields with known values with the Gleap Ionic Capacitor SDK. Follow the integration code examples.

In some situations you might want to prefill some fields for the user. This can be achieved by the following method.

```javascript
Gleap.preFillForm({
  data: {
    description: "This text will be prefilled.",
    errordescription: "This text will be prefilled as well.",
    someformidentifier: "This text will also be prefilled.",
  },
});
```

Use the field ID of the attribute assigned to the form question as the key. Open AI agents → Forms, select the form and question, and check Attribute (field ID). You can also find field IDs under Settings → Inbox & tickets → Data attributes.
