Restrict funds

New

The restrict funds feature is now live. This feature enables financial institutions to instantly block or restore account fund access—individually or in bulk—based on regulatory, fraud, or client-driven requirements. You can block full or partial amounts in your clients’ accounts either due to request or judicial/regulatory events such as liquidation or receivership. This feature includes four endpoints:

• Create fund restriction
• Get fund restriction
• List fund restrictions
• Release restriction

Payments

Updated

The new original_authorization request field is available on the Create cash-in or cash-out endpoint.

Setup

Docs

The missing program parameter "Overlimit fee amount" was added to the Program parameters guide.

Banking operations

New

The following new endpoints are now available:

• Withdraw money
• Cancel account
• List Org interest plans
• Configure timing for division accrual calculation

Transaction banking

New

The following new operation block endpoints (v2) are now available. They allow you to block all operations for entire account groups, while still permitting certain authorized activities—such as earmarks or check processing. This ensures that essential internal processes can continue even when most activities are frozen.

• Create operation block
• List operation blocks
• Get operation block details
• Update operation block
• Revoke operation block

New

The check posting API is now available in beta release. It allows you to post a check to a specified external account, with the option to settle the amount immediately or at a future date. This API includes the following endpoints:

• Create check posting
• Get check posting
• Release check
• Cancel check

Docs

The following new guides are now available:

• Get started with transaction banking provides step-by-step instructions for onboarding to transaction banking.
• Operation block allows financial institutions to temporarily restrict account activity at the program, division, or organization level.
• Restrict funds enables financial institutions to block full or partial amounts in their clients’ accounts. This capability is essential in situations where specific funds must be excluded from the general asset pool available to unsecured creditors, ensuring they receive priority handling or special protection.
• File-based processing allows you to upload UTF‑8 NDJSON files that contain a specific operation type, such as RESTRICT_FUNDS, to execute multiple transactions in bulk. Each file is processed asynchronously, line by line, ensuring that a failure in one instruction does not halt the rest.

Card network integration

Docs

The following new validation codes were added to the Validation code definitions guide:

• CTT - Card token timeout
• OOT - Orgs-API timeout

Statements

Updated

The following event files were updated and moved to the appropriate Statement refinancing section.

• Payment agreement simulation processed
• Payment agreement simulation not processed
