When configuring a new journey, one of the Trigger options is Webhook. A webhook-triggered journey will provide an explicit Webhook Endpoint URL to be used for triggering the journey.

❗️

When cloning a journey, a new explicit Webhook Endpoint URL will be generated.

Journeys can be triggered by sending a POST request to the provided Webhook Endpoint URL with the following payload structure:

Param NameRequiredTypeDescription
emailYesStringThe email address of the customer
session_dataNoJSON ObjectMetadata to be attached to the customer's journey session metadata

🚧

The customer must already exist in your site account, which means there must have been a previous interaction, such as a previously identified cart or browse session, being added to a list, etc.

If you want to ensure that every customer used to trigger a webhook journey already exists, you can use the Create Customer Profile endpoint prior to triggering the journey.
