Event Topic Definitions

Newline provides real-time event notifications through both Webhooks and the Message Queue (MQ). Events are grouped into topics, which represent categories of related actions or changes—such as updates to Transactions, Synthetic Accounts, and other key entities.

Clients can subscribe to topics that align with their business needs. Subscriptions may be configured to receive:

• All events within a topic (e.g., all transfer-related events)
• Specific events within a topic (e.g., RTP Settlement but not Transfer Initiated)
• A combination of topic-level and event-level subscriptions

📘

Note For guidance on how events are delivered and authenticated, see the Webhooks & Message Queue Documentation is identifying which topics support your operational or customer-facing workflows.

For example, consider the Transfer topic. If your application needs to track the status of a transfer, you can subscribe to this topic. When a status change occurs, Newline will send an event—via Webhook or MQ—that includes a payload which can be used to:

• Update your user interface
• Trigger internal workflows
• Send push notifications or alerts
