Webhook Event Subscriptions

Newline will work with clients to define the webhook events they would like to receive. These events can include changes to Transactions, Synthetic Accounts, and other key entities—tracking their states and statuses in real time. Events are grouped into topics, and clients can subscribe to the topics that are relevant to their use cases.

Payments Use Cases

An important part of webhook configuration is identifying which topics align with your business needs—whether for internal operations or customer-facing features.

For example, consider Transfers. If your application needs to track the status of a transfer, you can subscribe to the Transfer topic. When a status change occurs, Newline will send a webhook event to your system. This event includes a payload that can be used to:

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