OpnForm embeds now come with a JavaScript SDK for more control over embedded forms.

The SDK automatically initializes your iframe, handles resizing, and gives developers a clean way to listen to form events or control form data from the host page. You can react to submissions, track data changes, prefill fields, move between pages, reset forms, and connect embedded forms to your own product flows.

It is designed for teams who need forms to feel native inside their website, app, or customer portal.

• Listen for events like ready, submit, data change, page change, reset, and errors.

• Set, clear, and read field values programmatically.

• Control navigation in multi-page forms.

• Use the SDK with embedded forms and custom code workflows.
