Handling webhooks

Use functions to reshape webhook payloads before Hightouch writes them to your warehouse or sends them to destinations.

These webhooks usually contain event data that are helpful for building a full profile of your users. For example, Shopify has webhooks for when users check out, and Iterable has webhooks for when users open emails.

To set this up, create a webhook source and add it to the tool that emits events. You can then process the raw webhook data using functions.

For example, your code might look something like:

async function transformEvents(events) {
  return events.map((event) => ({
    ...event,
    type: "track",
    event: event.event,
    messageId: event.messageId,
    properties: {
      ...event.properties.body.dataFields,
      email: event.properties.body.email,
    },
    anonymousId: event.properties.body.userId
      ? null
      : event.properties.body.email,
    userId: event.properties.body.userId,
  }));
}
