Numeral’s bank simulator enables customers or connectivity providers to simulate real-world payment flows, either via the API or directly from the dashboard.

To perform these simulations, you can either use built-in scenarios or upload bank or CSM messages:

• Built-in scenarios are supported in both the API and the dashboard (through a dedicated Simulator screen) with Numeral’s mock bank Demo Bank
• Uploading bank or CSM messages is only available in the API and supports both Numeral’s mock bank Demo Bank and your own partner banks

The dashboard version of the bank simulator is available in sandbox. It currently supports updating payment order statuses and creating account balances, with more scenarios coming soon, including creating incoming payments and creating transactions

Learn more in our Bank simulator guide.

In order to improve the readability of the Payee verification request object, we have renamed requesting_agent into requesting_agent_bank_code and responding_agent into responding_agent_bank_code.

Numeral now enables customers to monitor connectivity with partner banks, CSMs, and connectivity providers.

Connectivity syncs are created whenever Numeral connects to a partner bank, CSM, or connectivity provider to send and receive payments and reports.

Users can:

• Monitor data exchanges initiated by Numeral
• View connectivity sync status (success, failure, or warning) with associated timestamps and metadata
• Filter connectivity syncs by type, status, connected account, or date via the API

Each connectivity sync is linked to one or more connected accounts and includes lifecycle information to help users track operational issues of payment processing.

This feature is accessible via the API.

Swift GPI payment tracking now available in the dashboard

Customers can now track payments using Swift GPI directly in the dashboard. Swift GPI-tracked payments have a new Swift GPI tracking tab with their processing timeline and status across correspondent banks.

This feature is part of Swift GPI tracking through partner banks.

Numeral now supports the 2025 SEPA rulebooks published by the European Payments Council.

Changes to the API include:

• Addition of an initiated_at attribute for SCT Inst payment orders and incoming payments
• Support for hybrid postal addresses
• Support for organization identification

Learn more in 2025 SEPA rulebooks.

Customers can now find their preferred support channels directly in the Numeral dashboard from the main navigation bar.

The support screen includes:

• Support contact details
• Business hours
• Documentation
• Process to raise an incident

We have improved how events and deliveries are displayed in the Numeral dashboard.

Delivery status on the Developers > Events screen now includes the count of deliveries:

Events now include a Deliveries tab with the list of deliveries for this event.

Users can now create and manage account holders directly from the Numeral dashboard. Account holders can be linked to internal accounts and external accounts to centralise account holder data, including name and metadata.

Numeral now supports ClearBank. ClearBank customers can connect their accounts to send and receive payments and access bank account balances and transactions using Numeral.

Numeral now supports Swift GPI tracking to enable customers to track cross-border payments sent and received through their partner banks.

Specifically, they can:

• Attach a unique end-to-end transaction reference (UETR) (uetr) to Swift payment orders
• Retrieve and filter payment orders and incoming payments by UETR
• View UETRs on incoming Swift payments (when available in pacs.008 messages)
