Dojo Events

Dojo Events are notifications about changes relating to entities which are owned by the Dojo API and allow a POS system to be able to react in near real time. These events are sent by Dojo with at-least-once semantics to a POS system, via the HandleEvent(REST or WS) capability.

An event payload contains a unique event id, the accountId specific to the location for whom the event is intended, when the event was createdAt, the event type in event, and data about the event.

The Dojo Events API will always differentiate between the states of an entity, such as being created or updated. When an entity is created by Dojo, a created event will be sent, and when that entity is updated, a status_updated event will be sent.

The difference between these events and POS Events is that these events pertain to entities owned by Dojo and are sent from Dojo to the POS system. In contrast, POS Events pertain to entities owned by the POS system and are sent from the POS system to Dojo

Dojo Events function similar semantically to Webhooks in payload and functionality; If both the capability and webhook for an event are registered, that event will need to be handled idempotently as per the principle of at-least-once, as it will be sent by Dojo twice.

Event Types

Below is information about the various event types that can be sent by Dojo to the POS system, including why Dojo sends it, the data it holds, and links to the relevant entity documentation.

Event Type	Description	Data
`payment_intent.created`	Whenever a Payment Intent is created, this will trigger when a payment is prepared to be taken using a Dojo Product or if one is created through an API Request	`paymentIntentId` `paymentStatus` `captureMode`
`payment_intent.status_updated`	Whenever a Payment Intent is updated, this will trigger when the status of a payment intent changes, such as being Captured or Cancelled.	`paymentIntentId` `paymentStatus` `captureMode`

Capabilities

In the Dojo EPOS Data API, capabilities represent specific actions that the POS system can perform. These capabilities are linked to corresponding API endpoints in the POS system. By defining these capabilities, the POS system communicates to Dojo which features are supported and accessible.
