v1.5.0

Happy summer from the ModernFi team! See below for our latest API updates.

This update removes legacy ledger transaction support and introduces enhancements that align with new account routing features and improved reconciliation workflows. These changes pave the way for more seamless integrations with external financial systems.

Removed Endpoints

  • GET /v1/accounts/{account_id}/ledger-transactions — Deprecated and removed. This endpoint previously returned raw ledger transaction data.

Updated Endpoints

  • GET /v1/accounts/{account_id}/documents/monthly-statements — Updated request/response schema to support richer metadata and future extensibility.

  • GET /v1/accounts/{account_id}/transactions — Response schema updated to include new institution metadata fields.

  • PATCH /v1/accounts/{account_id}/transactions/{transaction_id} — Now accepts institution_transaction_id in the request payload for improved traceability.

Schema Changes

  • Additional metadata fields introduced across document and transaction schemas to support future expansion.
