Documentation

FormsortWebEmbed(rootEl: HTMLElement)

Initializes a Formsort iframe as a child of the rootEl provided.

loadFlow(clientLabel: string, flowLabel: string, variantLabel?: string) => void

Starts loading a Formsort variant, or a flow.

Note that variantLabel is optional: if it is not provided, a variant will be chosen at random from that flow.

setSize(width: number, height: number) => void

Set the CSS size of the embed.

You may also style the embed's iframe using CSS - it is the iframe child of the rootEl, so you'd use the selector #rootEl > iframe.

onFlowLoaded: () => void

Set a callback function to be called when the Formsort flow has loaded completely.

Note that this is more accurate than listening for the iframe's load event, as this is sent from within the Formsort application code.

You can use this to do things like hide the frame container, or display a loading indicator, until everything is loaded to ensure a seamless initial experience.

const embed = new FormsortWebEmbed(document.body);
embed.onFlowLoaded = () => {
  console.log('Flow has loaded!');
};
embed.loadFlow('formsort', 'onboarding', 'main');

onFlowFinalized: () => void

Set a callback to be called when the flow is compete, meaning the user has finished all of the steps available to them.

Useful for performing an action after the flow is complete, such as displaying a congratulations or starting a payment process.

onFlowClosed: () => void

Set a callback to be called when the user abandons the flow before finalizing it.

Note that this is only possible if your style set defines a close button.
